What is known
The MasterStudy LMS plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.3.1. This is due to insufficient validation checks within the _register_user() function called by the 'wp_ajax_nopriv_stm_lms_register' AJAX action. This makes it possible for unauthenticated attackers to register a user with administrator-level privileges when MasterStudy LMS Pro is installed and the LMS Forms Editor add-on is enabled.
Business impact
Successful exploitation of CVE-2024-2409, a critical vulnerability (CVSS 9.8) affecting masterstudy lms, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
Recommended administrator action
Confirm whether masterstudy lms is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
