Authenticated code execution via unsafe image upload

Published Feb 21, 2023 · Updated Aug 2, 2024

Unrestricted file upload in Best POS Management System in PHP 1.0 allows remote authenticated users to execute server-side code. The save_settings image handler accepts a crafted img value such as ../../shell.php and stores dangerous content without restricting its path or file type. Administrative access to the site settings page is required, after which uploaded PHP content can run in the web server context.
