Vulnerability AssessmentAI

Exploitation No authentication is required - `/dets/forgot-password.php` is a pre-authentication password recovery page by design, accessible to any remote user without credentials. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The reported CVSS 4.0 score of 5.5 (Medium) with impact metrics VC:L/VI:L/VA:L appears conservative for a classic unauthenticated SQL injection - typical SQLi against a PHP/MySQL backend enables full schema enumeration and credential extraction, warranting higher C/I ratings. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
