They forward ARP requests, which are sent as broadcast packets, between the host and the guest networks. To use this leakage as a direct covert channel, the sender can trivially issue an ARP request to an arbitrary computer on the network. (In general, some routers restrict ARP forwarding only to requests destined for the network's subnet mask, but these routers did not restrict this traffic in any way. Depending on this factor, one must use either the lower 8 bits of the IP address, or the entire 32 bits, as the data payload.)"}, {"lang": "es", "value": "Los dispositivos D-link DIR-825AC G1 poseen una Compartimentaci\u00f3n Insuficiente entre una red host y una red invitada que es establecida por el mismo dispositivo. Estos reenv\u00edan peticiones ARP, que se env\u00edan como paquetes de difusi\u00f3n, entre las redes host y las invitadas. Para usar esta filtraci\u00f3n como un canal secreto directo, el remitente puede emitir trivialmente una petici\u00f3n ARP hacia una computadora arbitraria sobre la red. (En general, algunos routers restringen el reenv\u00edo ARP solo a las peticiones destinadas a la m\u00e1scara de subred de la red, pero estos rotuers no restringieron este tr\u00e1fico de ninguna manera.
