Detection Guidance

The vulnerability in the WordPress School Management Plugin (versions 93.1.0 and below) is an Insecure Direct Object References (IDOR) flaw that allows unauthorized access to sensitive files or data without authentication.

To detect this vulnerability on your system or network, you can attempt to access restricted resources or data endpoints of the plugin without authentication and observe if access is granted.

Since there is no official patch or specific detection commands provided, a practical approach is to use web request tools like curl or automated scanners to test for unauthorized access to plugin-specific URLs or API endpoints.

• Use curl to attempt accessing known plugin resource URLs without authentication, for example: curl -i http://yourwordpresssite.com/wp-content/plugins/school-management/some-protected-resource
• Use web vulnerability scanners that support IDOR detection against the WordPress site, focusing on the School Management plugin endpoints.
• Monitor web server logs for unusual access patterns to the plugin's files or database interaction points without valid user sessions.
