CVE-2026-41228

CVE-2026-41228 · Froxlor has Local File Inclusion via path traversal in API `def_language` parameter that leads to Remote Code Execution

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Froxlor is open source server administration software. Prior to version 2.3.6, the Froxlor API endpoint `Customers.update` (and `Admins.update`) does not validate the `def_language` parameter against the list of available language files. An authenticated customer can set `def_language` to a path traversal payload (e.g., `../../../../../var/customers/webs/customer1/evil`), which is stored in the database. On subsequent requests, `Language::loadLanguage()` constructs a file path using this value and executes it via `require`, achieving arbitrary PHP code execution as the web server user. Version 2.3.6 fixes the issue.
