Technical details
A SQL injection vulnerability exists in SourceCodester Class and Exam Timetabling System 1.0 within the '/edit_subjecta.php' file. The root cause is the improper neutralization of the 'id' GET parameter before it is used in a database query. A remote, unauthenticated attacker can exploit this by sending specially crafted SQL payloads (including boolean-based blind, error-based, and UNION-based techniques) to manipulate database queries. Successful exploitation allows for unauthorized data retrieval, modification, or deletion. No patches are currently reported; remediation should include implementing prepared statements with parameterized queries.
