Authenticated local PHP file inclusion via sub_page

Published Apr 22, 2021 · Updated Aug 3, 2024

Local file inclusion in Themeum Tutor LMS before 1.8.8 allows remote authenticated users with high privileges to include local PHP files. The Tools page uses a traversal-bearing sub_page value to select a PHP file without restricting the path to an approved page name. Access to the WordPress administrative Tools endpoint is required, and the selected local PHP file is processed in the site context.
