| विवरण | The administrator login endpoint constructs an SQL query by directly embedding the user‑supplied `a_usr` (username) and `a_pwd` (password) without any sanitisation or parameterisation:
```php
$a_usr = $_POST['a_usr'];
$a_pwd = $_POST['a_pwd'];
$ret = mysqli_query($con, "SELECT * FROM admin WHERE userid='$a_usr' AND password='$a_pwd' ");
```
Because no input validation or query parameterisation is applied, an attacker can inject a boolean‑based payload into the username field. The payload admin' OR '1'='1 transforms the query into one that always returns at least one row, completely bypassing the password check. The server then sets a session and redirects to the admin dashboard, granting full administrative access. |
