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.
