TITLE

Edimax BR-6208AC V1 Device access control vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-008739

DESCRIPTION

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.). Edimax BR-6208AC V1 The device contains an access control vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The Edimax BR-6208AC is a wireless concurrent dual-band router. Edimax BR-6208AC V1 has a hidden channel vulnerability across routers. An attacker could exploit this vulnerability to make ARP requests to any computer on the network. Edimax Technology BR-6208AC is a wireless router manufactured by Edimax Technology, Taiwan, China
