| Title | PHPGurukul Bank Locker Management System (BLMS) v1.0 SQL Injection |
|---|
| Description | An unauthenticated blind SQL injection vulnerability exists in `Bank Locker Management System 1.0` in the file `/blms/banker/check_availability.php`. The endpoint is an AJAX handler used by the `add-subadmin.php` form to check username availability, but it performs no session validation and directly concatenates the `username` POST parameter into a SQL query without sanitization or parameterization. Because the response is a boolean oracle (different output for "exists" vs "available"), an unauthenticated attacker can conduct time-based or boolean-based blind SQL injection to extract the entire `tblbanker` table, including administrator password hashes. |
