Vulnerability AssessmentAI
| Exploitation | Based on the CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N), no authentication, special configuration, or user interaction is required. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 5.5 (Medium) reflects low-severity impacts across confidentiality, integrity, and availability (VC:L/VI:L/VA:L), consistent with a SQLi that enables partial data extraction and manipulation but not necessarily full database compromise or remote code execution. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker discovers an internet-exposed instance of the Class and Exam Timetabling System and sends a crafted HTTP request to /edit_class1.php with a SQL-injected ID parameter value (e.g., ID=1 UNION SELECT ...) drawn from the publicly available POC on GitHub. The unsanitized query executes against the backend database, returning table contents including potentially stored credentials or student/schedule data. … |
| Remediation | No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
