 ## 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.
 
 **Example of Command Injection with PHP**:    
 Suppose you have a PHP script that takes a user input to ping a specified IP address or domain:
 
 ```php

 This means the system would first `ping 8.8.8.8` and then execute the `cat /etc/passwd` command, which would display the contents of the `/etc/passwd` file, potentially revealing sensitive information.

 ### Chaining Commands
 
 In many command-line interfaces, especially Unix-like systems, there are several characters that can be used to chain or manipulate commands. 
 
 
 * `;` (Semicolon): Allows you to execute multiple commands sequentially.
 * `&&` (AND): Execute the second command only if the first command succeeds (returns a zero exit status).
 * `||` (OR): Execute the second command only if the first command fails (returns a non-zero exit status).

 ### 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.

+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.

+## System Prompt
+
+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

 ## 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.
