Vulnerability AssessmentAI

Exploitation The `/edit_subject2.php` file must be reachable over the network by the attacker - no authentication, no privileged session, and no user interaction are required, as confirmed by the CVSS 4.0 vector (PR:N/UI:N/AC:L/AT:N). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 6.9 with vector AV:N/AC:L/AT:N/PR:N/UI:N reflects low-complexity, unauthenticated, remote exploitation - a significant real-world risk factor. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated remote attacker sends an HTTP request to the publicly accessible `/edit_subject2.php` endpoint with a crafted `ID` parameter - for example, `ID=1' OR 1=1 UNION SELECT username,password,NULL FROM users--` - causing the PHP application to pass the unsanitized input directly to the database engine. The database executes the injected query, returning credential data or other records the attacker can harvest. …
Remediation No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.
