|---|
| 説明 | The login script constructs an SQL query by directly concatenating the user‑supplied `username` and the MD5 hash of the `password` into the query string:
```php
$name = $_POST['username'];
$pass = md5($_POST['password']);
$sql = "SELECT * FROM USERS WHERE USERNAME='".$name."' AND PASSWORD='".$pass."' ";
$result = mysqli_query($data, $sql);
```
No parameterisation, escaping, or input validation is applied. An attacker can inject arbitrary SQL logic into the username field to bypass the password check entirely. Upon successful injection, the server sets a valid session and redirects to the admin dashboard, giving the attacker full administrative privileges. |
