How to fix?

Upgrade froxlor/froxlor to version 2.3.6 or higher.

Overview

froxlor/froxlor is a server administration software.

Affected versions of this package are vulnerable to PHP Remote File Inclusion via the def_language parameter in the API, which is not properly validated against the list of available language files. An attacker can execute arbitrary PHP code as the web server user by uploading a malicious .lng.php file to their web directory and setting the def_language parameter to a path traversal payload that points to this file. This allows full server compromise, lateral movement, persistent backdoor installation, and data exfiltration.
