regex: admin:.*:*sh$

• → Detect exploitation attempts by monitoring HTTP GET requests to /command.cgi with command injection payloads in the query string (e.g., URL-encoded shell commands such as cat%20/etc/passwd). ↗
• → A successful exploit response will contain a passwd-file entry matching the pattern 'admin:.*:*sh$' with HTTP status 200, indicating unauthenticated or authenticated RCE via the CGI endpoint. ↗
• → The vulnerable CGI endpoint is only accessible to authenticated users; monitor for brute-force or credential-stuffing attempts against the admin interface prior to /command.cgi access. ↗

• · Exploitation requires authentication as admin; the attack surface is limited to users who have obtained the admin configuration password. ↗
• · Vulnerability has only been confirmed on the 420HD model running firmware 2.2.12.126; other 400HD series models or firmware versions have not been tested. ↗
