Technical details

A SQL injection vulnerability exists in the /delete_subject.php file due to insufficient input validation on the 'id' parameter. User-supplied input is directly concatenated into SQL queries without using prepared statements or parameterized queries. The vulnerability is remotely exploitable over the network without authentication or user interaction required. Attackers can exploit this to extract sensitive data, modify or delete database records, bypass access controls, or potentially achieve code execution depending on database permissions. Multiple SQL injection techniques (boolean-based blind, error-based, time-based blind, and UNION-based) have been confirmed to work against the vulnerable parameter.
