Descriptions

It was possible to bypass policies configured for Zero Trust Secure Web Gateway by using warp-cli 'set-custom-endpoint' subcommand. Using this command with an unreachable endpoint caused the WARP Client to disconnect and allowed bypassing administrative restrictions on a Zero Trust enrolled endpoint.

Era posible omitir las políticas configuradas para Zero Trust Secure Web Gateway mediante el subcomando warp-cli 'set-custom-endpoint'. El uso de este comando con un punto final inalcanzable provocó que el cliente WARP se desconectara y permitió eludir las restricciones administrativas en un punto final inscrito en Zero Trust.
