CVE-2026-41229 Details
Description
Froxlor is open source server administration software. Prior to version 2.3.6, `PhpHelper::parseArrayToString()` writes string values into single-quoted PHP string literals without escaping single quotes. When an admin with `change_serversettings` permission adds or updates a MySQL server via the API, the `privileged_user` parameter (which has no input validation) is written unescaped into `lib/userdata.inc.php`. Since this file is `require`d on every request via `Database::getDB()`, an attacker can inject arbitrary PHP code that executes as the web server user on every subsequent page load. Version 2.3.6 contains a patch.
A PHP code injection vulnerability exists in Froxlor versions prior to 2.3.6. The issue arises in the `PhpHelper::parseArrayToString()` method, which writes string values into single-quoted PHP string literals without properly escaping single quotes. When an admin with `change_serversettings` permission adds or updates a MySQL server through the API, the `privileged_user` parameter is transmitted unescaped into `lib/userdata.inc.php`. This file is included in every request via `Database::getDB()`, allowing an attacker to inject and execute arbitrary PHP code as the web server user on subsequent page loads.
Users can update to Froxlor version 2.3.6 or later, where this vulnerability has been patched. The update is available on the Froxlor GitHub releases page.
