| Title | PHPGurukul Bank Locker Management System (BLMS) v1.0 Unrestricted Upload |
|---|
| Description | An unrestricted file upload vulnerability exists in `Bank Locker Management System 1.0` in `/blms/banker/add-locker-form.php`.
The form accepts two file fields — `photo` and `addressproof`. The extension whitelist validation for `photo` is enforced, but
the identical validation for `addressproof` has been entirely commented out (lines 35-38). An authenticated attacker can upload
a valid image as `photo` and a `.php` webshell as `addressproof` in a single request. The PHP file is saved with a predictable
filename to the web-accessible `banker/addressproof/` directory, which has no `.htaccess` access restrictions, yielding remote
code execution. |
