Vulnerability AssessmentAI
| Exploitation | No special conditions are required for exploitation beyond network reachability of the `/edit_subject1.php` endpoint. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.9 (Medium) reflects limited but real impact across confidentiality, integrity, and availability - all rated Low - consistent with a SQL injection that allows partial data read/write rather than full database compromise or OS-level access. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker identifies an internet-exposed instance of the Class and Exam Timetabling System and sends a crafted HTTP GET or POST request to `/edit_subject1.php` with a malicious SQL payload in the `ID` parameter - for example, appending `' UNION SELECT username,password,3 FROM users-- -`. Because a public proof-of-concept exists on GitHub (https://github.com/i-QvQ-i/first-OvO/issues/7), the attacker can adapt existing exploit code with minimal effort to enumerate database tables, extract credentials, or modify timetable records. |
| Remediation | No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
