CVE-2020-10562Network attack vector

Administrator-level code execution via double-extension upload

Published Mar 13, 2020 · Updated Aug 4, 2024

Unrestricted file upload in DEVOME GRR before 3.4.1c allows remote authenticated users to execute PHP code on the web server. admin_edit_room.php checks only the final filename extension, but derives the stored extension from the second dot-separated segment and moves the file into the web-accessible images directory. Administrator access to room editing is required; a double-extension image name causes attacker-supplied PHP to be stored with a .php suffix.
