Executive brief
A critical security flaw has been identified in the itsourcecode Online Student Enrollment System, a platform used for managing student registrations. An attacker can exploit this vulnerability to gain unauthorized access to the underlying database, potentially leading to the theft of sensitive student and instructor information or the complete deletion of system data. This issue can be exploited remotely without requiring any login credentials.
Technical details
A SQL injection vulnerability exists in the 'instructorClasses.php' file of itsourcecode Online Student Enrollment System v1.0. The root cause is the improper neutralization of the 'classId' GET parameter, which is directly concatenated into a SQL query without sanitization or validation (CWE-89). This is a remote, unauthenticated attack vector requiring no user interaction. Successful exploitation allows an attacker to read, modify, or delete data within the database, and potentially gain administrative access to the application. As of the advisory date, no official patch has been confirmed, though users should implement prepared statements or input validation to mitigate the risk.
