Summary

The CAI (Cybersecurity AI) framework contains multiple argument injection vulnerabilities in its function tools. User-controlled input is passed directly to shell commands via subprocess.Popen() with shell=True, allowing attackers to execute arbitrary commands on the host system.

Vulnerable Component

Function: find_file() in src/cai/tools/reconnaissance/filesystem.py code

Attack Vector

An attacker can exploit this vulnerability through prompt injection:

1. Attacker hosts a webpage containing malicious instructions in HTML comments
2. Victim's CAI agent fetches and processes the webpage
3. Agent is tricked into calling find_file() with attacker-controlled arguments
4. The -exec flag enables arbitrary command execution

Proof of Concept

Malicious payload in HTML comments:

Resulting command execution:

Impact

The find_file() tool executes without requiring user approval because find is considered a "safe" pre-approved command. This means an attacker can achieve Remote Code Execution (RCE) by injecting malicious arguments (like -exec) into the args parameter, completely bypassing any human-in-the-loop safety mechanisms.
