## Technical details

An information disclosure vulnerability exists in the SQL Handler component of SourceCodester CET Automated Grading System with AI Predictive Analytics 1.0. The vulnerability is located in /index.php and can be triggered via the 'manage_subjects' action. By submitting oversized POST parameters (e.g., the 'program' field), a remote authenticated attacker can trigger database exceptions. The application fails to suppress these exceptions, returning verbose error messages that include SQLSTATE responses, PDO exceptions, and MariaDB/MySQL engine details. This exposure of backend architecture details assists in further reconnaissance and exploit development. A public exploit script is available.
