Is this vulnerability remotely exploitable?

Yes. An attacker with network access to the Online-Exam-System web interface can remotely submit crafted feedback requests to `feed.php` to exploit the blind SQL injection.

Does an attacker need to be authenticated to exploit this?

In many deployments, feedback forms are accessible to unauthenticated users, so exploitation may not require any prior authentication. However, the exact requirement depends on how access to the feedback functionality is configured.

What is the safest general fix pattern for this issue?

The most robust fix is to replace all dynamically constructed SQL in the feedback handling code with parameterized queries or prepared statements, ensuring user input is bound as data only, not as part of the SQL command. This should be applied consistently across the whole application, not just `feed.php`.
