| Mô tả | The `add.php` script inserts a new student record by directly concatenating `$_POST` fields (such as `name`, `address`, `fname`, etc.) into an SQL query without any sanitisation:
```php
$name = $_POST['name'];
...
$sql = "INSERT INTO student (name,fname,...) values('$name','$fname',...)";
```
Later, multiple pages display student data by echoing the raw database values directly into HTML without using htmlspecialchars() or any other output encoding:
echo "<td>".$row["name"]."</td>";
echo "<td>".$row["address"]."</td>";
An attacker can submit a student entry containing a malicious payload (e.g., <svg/onload=alert(1337)>) in fields like name or address. When any user (admin, teacher, student) views the student list or profile, the injected script executes in their browser, leading to session theft, cookie hijacking, and further compromise. |
