Descriptions

Edimax BR-6208AC V1 devices have Insufficient Compartmentalization between a host network and a guest network that are established by the same device. 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.)

Los dispositivos Br-6208AC V1 de Edimax tienen una compartimentación insuficiente entre una red host y una red de invitados establecida por el mismo dispositivo. Reenvían las peticiones ARP, que se envían como paquetes de broadcast, entre el host y las redes de invitados. Para utilizar esta fuga como un canal encubierto directo, el remitente puede emitir trivialmente una solicitud ARP a un equipo arbitrario de la red. (En general, algunos routers restringen el reenvío ARP solo a las solicitudes destinadas a la máscara de subred de la red, pero estos enrutadores no restringieron este tráfico de ninguna manera. Dependiendo de este factor, uno debe utilizar los 8 bits más bajos de la dirección IP, o los 32 bits enteros, como la carga útil de datos.)
