pathdb_controller.php↗

→Detect HTTP GET requests to OfficeScan endpoints where the Host header value does not match the server's actual hostname/IP (SERVER_NAME mismatch), indicating potential Host header injection/poisoning. ↗
→Monitor HTTP GET requests targeting db_controller.php with anomalous or external Host header values that differ from the legitimate OfficeScan server address. ↗

·Exploitation is most impactful in environments where HTTP caching is in place, as cached poisoned responses can serve malicious links to multiple users. ↗
·The vulnerability exists because db_controller.php uses $_SERVER['HTTP_HOST'] (attacker-controlled) instead of the safer $_SERVER['SERVER_NAME'] for constructing links; detection/mitigation should focus on enforcing SERVER_NAME usage or validating the Host header server-side. ↗
