Unauthenticated Remote Code Execution in AgenticSeek

Executive Summary

AgenticSeek has an unauthenticated remote code execution flaw. Attackers can send crafted queries to the unprotected POST /query API endpoint on port 7777. This allows them to execute arbitrary shell commands on the host system through BashInterpreter using subprocess.Popen with shell=True and safety=False, bypassing command blocklists.

Detection Guidance

Check if AgenticSeek is running on port 7777 by using commands like 'netstat -tulnp | grep 7777' or 'ss -tulnp | grep 7777'. Test the /query endpoint with a curl command like 'curl -X POST http://<target>:7777/query -H "Content-Type: application/json" -d '{"query":"test"}' to see if it responds without authentication.

Impact Analysis

An attacker on the same network could gain full control of the affected system. This includes executing malicious commands, stealing data, installing malware, or pivoting to other systems. The lack of authentication means any adjacent attacker can exploit it.
