Froxlor is open source server administration software. Prior to 2.3.8, the standalone lib/ajax.php entry point bypasses the centralized request validation in lib/init.php, and Ajax::handle in lib/Froxlor/Ajax/Ajax.php checks only for a valid session before routing state-changing requests. The editapikey action in Ajax::editApiKey updates allowed_from and valid_until without validating a CSRF token, while templates/Froxlor/assets/js/jquery/apikeys.js sends no token because the endpoint does not require one. An unauthenticated attacker can induce an authenticated administrator's browser to submit a forged request that adds an attacker-controlled address to an API key's allowed_from list or removes its expiration, weakening the key's security restrictions. This issue is fixed in version 2.3.8.
