Authenticated code execution via unrestricted image upload

Published Mar 9, 2026 · Updated Mar 9, 2026

Unrestricted file upload in SourceCodester Resort Reservation System 1.0 allows remote authenticated users to execute PHP code. The doInsert function in /controller.php?action=add accepts the image field and stores a PHP file in the web-accessible admin/mod_amenities/pics directory without blocking executable content. An account able to use the administrative image-upload path is required; successful exploitation runs attacker-supplied code in the web server context.
