| عنوان | imvks786 student_management_system 1.0 SQL Injection |
|---|
| الوصف | The application contains SQL injection vulnerabilities throughout nearly all database interaction points. User‑supplied input from `$_GET` and `$_POST` is concatenated directly into SQL queries without any parameterisation, escaping, or validation. This allows an attacker to manipulate query logic, leading to:
- **Authentication bypass** – log in as any user (including administrators) without valid credentials.
- **Unauthorised data deletion** – delete student records via `see.php?del=...`.
- **Unauthorised permission changes** – modify user roles via `admin/user_permission.php`.
- **Sensitive data exposure** – extract arbitrary data from the database using UNION‑based or blind techniques.
### Affected Code Examples
**1. Login bypass (department login):**
```php
// index.php
$usr = $_POST['usr'];
$pwd = $_POST['pwd'];
$ret = mysqli_query($con, "SELECT * FROM login WHERE username='$usr' AND password='$pwd' ");
