A vulnerability was detected in SourceCodester CET Automated Grading System with AI Predictive Analytics 1.0. This affects the function add_grade of the file /index.php. Performing a manipulation of the argument student_id results in improper authorization. The attack can be initiated remotely.
AnalysisAI
Improper authorization in SourceCodester CET Automated Grading System with AI Predictive Analytics 1.0 allows authenticated remote attackers to perform unauthorized grade operations against arbitrary student records by manipulating the student_id parameter in the add_grade function at /index.php. This is a horizontal privilege escalation flaw - an authenticated user (e.g., a student) can affect records they do not own, compromising both confidentiality and integrity of academic grade data. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated session with at least low-level privileges on the CET Automated Grading System (CVSS PR:L), consistent with a student, instructor, or operator account. … 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:L/UI:N/VC:L/VI:L/VA:L) assigns a score of 5.3 (Medium), which is consistent with a low-complexity network-reachable IDOR requiring only low-level authentication. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated student or staff member with a valid session crafts an HTTP request to /index.php targeting the add_grade function, substituting a victim student's student_id in place of their own. Because the server does not validate record ownership, the attacker's grade submission is applied to the target student's record, allowing grade inflation or sabotage of another student's academic standing. … |
| Remediation | No vendor-released patch has been identified at the time of analysis - SourceCodester projects are typically distributed as static downloadable scripts without formal patch channels. … Detailed patch versions, workarounds, and compensating controls in full report. |
