Descriptions

Zero Trust Administrators have the ability to disallow end users from disabling WARP on their devices. Override codes can also be created by the Administrators to allow a device to temporarily be disconnected from WARP, however, due to lack of server side validation, an attacker with local access to the device, could extend the maximum allowed disconnected time of WARP client granted by an override code by changing the date & time on the local device where WARP is running.

Los Administradores de Zero Trust tienen la capacidad de impedir que los usuarios finales deshabiliten WARP en sus dispositivos. Los administradores también pueden crear códigos de anulación para permitir que un dispositivo se desconecte temporalmente de WARP, sin embargo, debido a la falta de validación del lado del servidor, un atacante con acceso local al dispositivo podría extender el tiempo máximo permitido de desconexión del cliente WARP otorgado por un código de anulación cambiando la fecha y hora en el dispositivo local donde se ejecuta warp.
