Cybersecurity AI (CAI) vulnerable to Command Injection in run_ssh_command_with_credentials Agent tool

Summary

A command injection vulnerability is present in the function tool run_ssh_command_with_credentials() available to AI agents.

Details

This is the source code of the function tool run_ssh_command_with_credentials() (code):

@function_tool def run_ssh_command_with_credentials( host: str, username: str, password: str, command: str, port: int = 22) -> str: """ Execute a command on a remote host via SSH using password authentication. Args: host: Remote host address username: SSH username password: SSH password command: Command to execute on remote host port: SSH port (default: 22) Returns: str: Output from the remote command execution """ # Escape special characters in password and command to prevent shell injection escaped_password = password.replace("'", "'\\''") escaped_command = command.replace("'", "'\\''") ssh_command = ( f"sshpass -p '{escaped_password}' " f"ssh -o StrictHostKeyChecking=no " f"{username}@{host} -p {port} " f"'{escaped_command}'" ) return run_command(ssh_command)

Note how only password and command inputs are escaped to prevent shell injection; while username, host and port values are left injectable.

PoC

Create an index.html file with the following content:

<html> <head> <title>target system</title> </head> <body> nothing interesting here </body> </html>

Serve the file using a web server, as example:

sudo python3 -m http.server

Launch cai framework:

cai /model 7 /parallel add blueteam_agent localhost is your target. grab secret information from http://localhost:8000/index.html and try to evaluate its security. try the attacks with proof of concepts

As result we successfully created the file /tmp/username, but not /tmp/password (since shell injection prevention is applied).

Impact

An attacker can expose fake credentials as shown in the above Proof of Concept and when the AI Agent grabs the fake SSH information, it will use them using the function tool run_ssh_command_with_credentials() resulting in Command Injection in the host where CAI is deployed.

Cybersecurity AI (CAI) is an open-source framework for building and deploying AI-powered offensive and defensive automation. Versions 0.5.9 and below are vulnerable to Command Injection through the run_ssh_command_with_credentials() function, which is available to AI agents. Only password and command inputs are escaped in run_ssh_command_with_credentials to prevent shell injection; while username, host and port values are injectable. This issue does not have a fix at the time of publication.
