      "value": "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."

      "value": "Froxlor es un software de administración de servidores de código abierto. Antes de la versión 2.3.8, el punto de entrada independiente lib/ajax.php omite la validación centralizada de solicitudes en lib/init.php, y Ajax::handle en lib/Froxlor/Ajax/Ajax.php solo verifica una sesión válida antes de enrutar solicitudes que cambian el estado. La acción editapikey en Ajax::editApiKey actualiza allowed_from y valid_until sin validar un token CSRF, mientras que templates/Froxlor/assets/js/jquery/apikeys.js no envía ningún token porque el endpoint no lo requiere. Un atacante no autenticado puede inducir al navegador de un administrador autenticado a enviar una solicitud falsificada que añade una dirección controlada por el atacante a la lista allowed_from de una clave API o elimina su caducidad, debilitando las restricciones de seguridad de la clave. Este problema está corregido en la versión 2.3.8."
