Authenticated code execution via unvalidated image upload

Published Apr 1, 2024 · Updated Aug 1, 2024

Unrestricted file upload in SourceCodester Image Accordion Gallery App 1.0 allows remote authenticated users to execute PHP code. The add-image.php endpoint passes the image_name upload directly to move_uploaded_file under a unique name without validating its type or contents. A logged-in session is required, and a PHP payload saved beneath the web-accessible images directory executes with the web server privileges.
