CVE-2023-46004Public exploitNetwork attack vector

Administrator code execution via unrestricted PHP upload

Published Oct 18, 2023 · Updated Sep 13, 2024

Unrestricted file upload in Best Courier Management System 1.0 allows remote authenticated users to execute code through a PHP file. The update_user path in admin_class.php accepts an img multipart upload without rejecting a .php filename paired with an image MIME type, then stores it under a timestamp-derived name. Administrator access is required; locating and requesting the stored script executes arbitrary system commands with the web server account's privileges.
