CWE-98

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Froxlor versions before 2.3.6 are vulnerable. An authenticated customer can set the def_language parameter through the API to a path traversal value, causing the panel to include and execute an attacker-controlled PHP file, which can lead to arbitrary code execution as the web server user. Upgrade to Froxlor 2.3.6 or later. The source gives no workaround.
