CVE-2024-4916Public exploitNetwork attack vector

Database information disclosure via unparameterized thisId query

Published May 15, 2024 · Updated Aug 1, 2024

SQL injection in itsourcecode Online Examination System 1.0 allows remote authenticated users to infer database data via thisId. The selExamAttemptExe.php endpoint extracts POST fields and interpolates thisId directly into a SELECT query without parameterization. An active examinee session is required, and crafted predicates change the alreadyExam or takeNow response without directly returning query rows.
