A security flaw has been discovered in zhayujie CowAgent up to 2.1.7. Impacted is an unknown function of the file channel/web/web_channel.py of the component Web Console. The manipulation of the argument session_id results in denial of service.
The attack may be performed from remote. The exploit has been released to the public and may be used for attacks. Version 2.1.7 (commit dec28324) only partly mitigates via a 512MB body cap.
The vendor was contacted early about this disclosure.
