CVE-2021-46113Public exploitNetwork attack vector

Authenticated code execution via unrestricted room-image upload

Published Jan 25, 2022 · Updated Aug 4, 2024

Unrestricted file upload in MartDevelopers KEA-Hotel-ERP as of December 31, 2021 allows remote authenticated users to execute PHP code. The admin/rooms.php Add_Room handler passes the client-supplied image filename directly to move_uploaded_file in public/uploads/rooms without checking its extension or content type. An authenticated session able to add rooms is required; requesting the stored PHP file executes code with the web server process's privileges.
