Descriptions

Edimax BR-6208AC V1 devices have Insufficient Compartmentalization between a host network and a guest network that are established by the same device. In order to transfer data from the host network to the guest network, the sender joins and then leaves an IGMP group. After it leaves, the router (following the IGMP protocol) creates an IGMP Membership Query packet with the Group IP and sends it to both the Host and the Guest networks. The data is transferred within the Group IP field, which is completely controlled by the sender.

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. Para transferir los datos de la red del host a la red del invitado, el remitente se une y después deja a un grupo IGMP. Después de que salga, el router (siguiendo el protocolo IGMP) crea un paquete de la interrogación de la membresía IGMP con el IP del grupo y lo envía al host y a las redes del invitado. Los datos se transfieren dentro del campo IP de grupo, que está completamente controlado por el remitente.
