Remote code execution via unrestricted settings upload
Published Jun 2, 2022 · Updated Aug 3, 2024
Unrestricted file upload in Car Rental Management System 1.0 allows remote authenticated users to execute arbitrary PHP code. The save_settings action in admin/ajax.php accepts a multipart img upload named shell.php, stores it under admin/assets/uploads, and serves the file so its embedded PHP executes. The demonstrated request carries a PHP session cookie and reaches the administrative settings endpoint; successful exploitation installs a web-accessible server-side script.
