## Technical details

A SQL injection vulnerability exists in itsourcecode Courier Management System 1.0 within the 'manage_user.php' component. The application fails to sanitize the 'id' GET parameter before concatenating it into a SQL query string (e.g., SELECT * FROM users where id = ...). An unauthenticated remote attacker can exploit this by submitting malicious SQL payloads, including boolean-based, time-based, and UNION-based injections. Successful exploitation allows for full database enumeration, data extraction, and potential modification of user records. The vulnerability can be mitigated by implementing prepared statements with parameterized queries.
