| Title | andreashappe cochise v0.4.1 RCE |
|---|
| Description | Cochise is an LLM-driven pentest agent that connects to target machines via SSH. Two vulnerabilities combine to enable a second-stage remote code execution chain:
SSH host key verification is explicitly disabled (known_hosts=None), allowing man-in-the-middle attacks and connections to attacker-controlled SSH servers without any warning.
Raw SSH command output (including merged stderr) is appended directly to the LLM conversation history as a tool message with no filtering, sanitization, or taint marking. The LLM then generates and executes subsequent commands based on this untrusted input.
An attacker who controls a machine that Cochise connects to can inject prompt-injection text into the SSH session output, causing the LLM to generate malicious commands that Cochise will execute. |
