A critical vulnerability has been discovered in Campcodes Complete Web-Based School Management System 1., a widely used software solution for managing schools, which may allow attackers to gain unauthorized access to sensitive data or take control of the system. The vulnerability, identified as CVE-2024-5239, affects unknown code within the file /view/timetable_update_form.php. This could lead to SQL Injection attacks when the 'grade' argument is manipulated, potentially exposing user data or providing unauthorized access to the system.

This vulnerability has been assigned the identifier VDB-265990, and threat actors may exploit it remotely. Given the potential importance of the affected software, it's crucial to address and mitigate this vulnerability as soon as possible. This post will provide an in-depth analysis of the vulnerability, including a code snippet, links to original references, and details about the exploit.

The vulnerable code from /view/timetable_update_form.php appears as follows

$grade = $_GET['grade'];
$query = "SELECT * FROM timetable WHERE grade = '$grade'";
$result = mysqli_query($conn, $query);

An attacker may be able to inject malicious SQL code by manipulating the 'grade' argument, as there is no proper sanitization of the user's input.

Exploit Details

Since this vulnerability can be exploited remotely, attackers can potentially gain unauthorized access to sensitive data or control of the affected system by merely passing malicious SQL code as part of the 'grade' argument. Below is a simple example of such an attack:

http://example.com/view/timetable_update_form.php?grade=';; DROP TABLE users; --

In this example, a malicious user injects SQL code to drop the user's table in the database, resulting in data loss, or even worse, providing unauthorized access to other parts of the system.

Mitigation and Conclusion

To secure your Campcodes Complete Web-Based School Management System 1. from this critical vulnerability, it is crucial to apply proper sanitation and validation measures to user inputs, especially when handling data that can be manipulated in SQL queries. This can be achieved by using prepared statements to separate data from SQL commands, which would prevent SQL injection attacks.

As a software user, it is crucial to keep your software updated and apply patches as soon as possible. If the software vendor releases an update to address CVE-2024-5239, make sure to update your system right away.

Please stay vigilant and report any suspicious activity to the appropriate authorities. The discovery and disclosure of CVE-2024-5239 should serve as a reminder to software providers to prioritize security when developing their products.
