What is CVE-2019-13266?
CVE-2019-13266 is a high-severity vulnerability in n/a, published on 27 Aug 2019. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
Weakness: CWE-669
