An attacker could exploit this vulnerability by sending a malicious DHCPv4 message to or through a WAN interface of an affected device. A successful exploit could allow the attacker to cause a reload of the affected device.\r Note: On Cisco cBR-8 Converged Broadband Routers, all of the following are considered WAN interfaces:\r \r 10 Gbps Ethernet interfaces\r 100 Gbps Ethernet interfaces\r Port channel interfaces that include multiple 10 and/or 100 Gbps Ethernet interfaces\r \r "
