CVE-2024-2411Network attack vector

Unauthenticated PHP execution via modal path traversal

Published Mar 29, 2024 · Updated Apr 8, 2026

Local file inclusion in StylemixThemes MasterStudy LMS 3.3.0 and earlier allows remote attackers to execute server-side PHP via modal. The AJAX load_modal function prefixes modals/ to the untrusted modal value, passes it through locate_template, and includes any existing PHP file without blocking path traversal. A valid public nonce is required, and execution depends on an includable PHP file on the server, although a pearcmd.php chain was demonstrated.
