A critical vulnerability has been discovered in the Campcodes Student Grading System 1., a popular online platform for managing and tracking student performance. Researchers have found that an attacker can exploit this vulnerability to execute arbitrary SQL commands, potentially allowing them to gain unauthorized access to sensitive information or even take control of the system. This vulnerability, identified as CVE-2025-0212, affects an unknown part of the file /view_students.php.

Exploit Details

The vulnerability stems from insufficient input validation in the handling of the 'id' parameter within the /view_students.php file. By manipulating the 'id' parameter, an attacker can inject malicious SQL commands into the system. This type of vulnerability is commonly known as SQL Injection (SQLi). The attack can be initiated remotely, making it even more dangerous.

The SQL injection in the file can be easily reproduced by accessing the following URL

http://target/view_students.php?id=[SQL Injection Payload]

' or '1'='1

This would effectively alter the SQL query to return all records, bypassing any intended restrictions.

Here's a more detailed code snippet showcasing the vulnerability

// view_students.php
$id = $_GET['id'];
$query = "SELECT * FROM students WHERE id = $id";
$result = execute_query($query);

In the code above, the $_GET['id'] parameter is directly used in the SQL query without any sanitization or validation. This allows the attacker to inject their own SQL statements by simply modifying the 'id' parameter in the URL.

Mitigation

To mitigate this vulnerability, it is essential to validate and sanitize any user-supplied input before using it within SQL queries. One effective method of doing so is by using prepared statements:

$id = (int) $_GET['id'];
$query = "SELECT * FROM students WHERE id = ?";
$stmt = $conn->prepare($query);
$stmt->bind_param("i", $id);
$stmt->execute();
$result = $stmt->get_result();

In the updated code, we cast the 'id' parameter to an integer and use prepared statements which eliminate the risk of SQL injection.
