Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid low-privilege authenticated account on the school management platform, such as a parent or student portal login (CVSS PR:L - unauthenticated exploitation is not supported per the available vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 2.1 accurately reflects the constrained real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated user with a low-privilege parent account logs into the school portal and identifies that the marks endpoint in Parents.php accepts a param1 argument. By iterating numeric values for param1 in crafted HTTP requests, the attacker retrieves academic mark records belonging to other students' accounts without any authorization error from the server. … |
| Remediation | No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
