Vulnerability AssessmentAI
| Exploitation | No authentication is required - the CVSS 4.0 vector confirms PR:N/UI:N, meaning the endpoint is accessible without logging in. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) with supplemental exploitation metric E:P indicates a remotely exploitable, low-complexity vulnerability with publicly available proof-of-concept code and no authentication barrier. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker - or an enrolled student - sends a crafted HTTP request to /ajax_enroll.php with a manipulated student_id belonging to another user and an action value such as enroll or drop, with no session token or privilege check enforced by the server. The server processes the request and modifies or discloses the target student's enrollment data. … |
| Remediation | No vendor-released patch or fixed version has been identified at time of analysis - the product is an open-source academic project and SourceCodester does not maintain a formal security advisory process. … Detailed patch versions, workarounds, and compensating controls in full report. |
