|---|
| Description | The affected components are `Admin/mlogin.php` (manager login) and `Admin/dlogin.php` (doctor login). Both handlers concatenate the submitted `uname` and `pass` POST values into the query:
```php
// Admin/mlogin.php
$query = mysqli_query($conn,"SELECT * FROM manager where username = '$_POST[uname]' AND password = '$_POST[pass]'");
// Admin/dlogin.php
$query = mysqli_query($conn,"SELECT * FROM doctor where username = '$_POST[uname]' AND password = '$_POST[pass]'");
```
An unauthenticated attacker can submit `nomanager' OR '1'='1' -- -` (or the same payload against `dlogin.php`) to make the condition always true, obtaining a manager or doctor session and bypassing the login.
