An issue was discovered in SecurePoint UTM before 12.2.5.1. The firewall's endpoint at /spcgi.cgi allows sessionid information disclosure via an invalid authentication attempt. This can afterwards be used to bypass the device's authentication and get access to the administrative interface.

• → Monitor for POST requests to /spcgi.cgi with an empty 'sessionid', 'user', and 'pass' in the JSON body — this is the first stage of the exploit that triggers session ID disclosure. ↗
• → Detect a follow-up POST to /spcgi.cgi with module 'system' and command 'config get' using a sessionid obtained from the prior unauthenticated request — this indicates authentication bypass. ↗
• → A JSON response containing '"status":"OK"' from /spcgi.cgi following an unauthenticated login attempt confirms successful authentication bypass. ↗
• → Use Shodan/FOFA queries to identify exposed SecurePoint UTM instances: Shodan title:"Securepoint UTM", FOFA title="securepoint utm", Google intitle:"securepoint utm". ↗

• · The vulnerability affects SecurePoint UTM versions before 12.2.5.1 only; patched versions are not susceptible. ↗
• · The exploit is a two-step process: first an invalid authentication attempt leaks a sessionid, then that sessionid is reused to access the administrative interface — single-request detections will miss the full attack chain. ↗
