Overview
Cybersecurity threats are a growing concern in the digital realm, and this blog post will delve into one such vulnerability identified as CVE-2025-6079. This particular vulnerability affects the School Management System for WordPress plugin, used widely by educational institutions for administrative and organizational purposes. It is critical because it lacks file type validation in the homework.php file, thereby allowing authenticated attackers to upload arbitrary files. This could potentially lead to a system compromise or data leakage, resulting in severe consequences for the affected institutions.

How the Exploit Works
The exploit takes advantage of the lack of file type validation in the homework.php file of the School Management System for WordPress plugin. This allows an authenticated user with student-level access to upload arbitrary files to the server. The files can contain malicious code, which, when executed, could compromise the entire system. The attacker could potentially gain unauthorized access to sensitive information or exert control over the system.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited using an HTTP POST request to upload a malicious file:
POST /wp-content/plugins/school-management/homework.php HTTP/1.1
Host: target.school.edu
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary
------WebKitFormBoundary
Content-Disposition: form-data; name="fileToUpload"; filename="malicious.php"
Content-Type: application/x-php
<?php
// malicious code here
?>
------WebKitFormBoundary--In the above example, ‘malicious.php’ is a PHP file containing malicious code. Once uploaded and executed, it could potentially compromise the system.
Mitigation Guidance
To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it is available. Until then, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation. Regular monitoring and updating of systems is essential in maintaining cybersecurity.
