Is this vulnerability remotely exploitable?

Yes. An attacker with network access to the Student Web Portal can send crafted HTTP requests to /check_user.php with a malicious Username value.

Does an attacker need a valid account to exploit this issue?

Not necessarily. If /check_user.php is accessible before authentication (as is typical for login or user-check endpoints), the vulnerability can be exploited without valid credentials.

What is the safest general fix pattern for this vulnerability class?

The most robust fix is to replace all dynamically built SQL queries with parameterized queries or prepared statements, ensuring user input is always treated as data and never as executable SQL.
