https://notcve.org/view.php?id=CVE-2019-13266
TP-Link Archer C3200 V1 and Archer C2 V1 devices have Insufficient Compartmentalization between a host network and a guest network that are established by the same device. A DHCP Request is sent to the router with a certain Transaction ID field. Following the DHCP protocol, the router responds with an ACK or NAK message. Studying the NAK case revealed that the router erroneously sends the NAK to both Host and Guest networks with the same Transaction ID as found in the DHCP Request. This allows encoding of data to be sent cross-router into the 32-bit Transaction ID field. • https://orenlab.sise.bgu.ac.il/publications/CrossRouter https://www.usenix.org/system/files/woot19-paper_ovadia.pdf • CWE-669: Incorrect Resource Transfer Between Spheres •

TP-Link Archer C3200 V1 and Archer C2 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 TP-Link Archer C3200 V1 y Archer C2 V1 tienen una compartimentación insuficiente entre una red host y una red de invitados establecida por el mismo dispositivo. • https://orenlab.sise.bgu.ac.il/publications/CrossRouter https://www.usenix.org/system/files/woot19-paper_ovadia.pdf •

TP-Link Archer C3200 V1 and Archer C2 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.) • https://orenlab.sise.bgu.ac.il/publications/CrossRouter https://www.usenix.org/system/files/woot19-paper_ovadia.pdf • CWE-20: Improper Input Validation •
