CVE-2023-6659Public exploitNetwork attack vector

Database disclosure via student parameter SQL injection

Published Dec 11, 2023 · Updated Aug 2, 2024

SQL injection in CampCodes Web-Based Student Clearance System 1.0 allows remote authenticated users to disclose database data. The login handler accepts the student form value as SQL syntax; the published POST proof uses a nested SLEEP expression to produce a time delay. A valid low-privilege session is required by the CNA assessment, and successful exploitation exposes database information through query or timing behavior.
