| Título | raisulislamg4 student_management_system_by_php 1.0 Unauthenticated Arbitrary User Creation |
|---|
| Descrição | The `add_user_check.php` script allows anyone to create a new user account, including administrative accounts, **without any authentication**. Although `session_start()` is called, there is no check to ensure the requester is logged in or has the necessary privileges (e.g., an existing admin). The script blindly inserts the supplied `role` value (from `$_POST['role']`) into the database:
```php
session_start();
if (isset($_POST['apply'])) {
$role_data = $_POST['role'];
...
$sql="INSERT INTO USERS(..., ROLE, PASSWORD)
VALUES(..., '$role_data', '$password_data')";
$result = mysqli_query($data, $sql);
if ($result) {
header("location:add_user.php");
}
}
An unauthenticated attacker can send a POST request with role=admin and immediately gain permanent administrator access to the application. |
