CBOS Multiple TCP Connections Denial of Service Vulnerability

CBOS is the Cisco Broadband Operating System, firmware designed for use on Cisco 600 series routers. It becomes unstable when it receives multiple TCP connections on one of the two administrative ports; 21 via telnet, or 80 via HTTP. Upon receiving multiple connections on one of these two ports, the 600 series router becomes incapable of configuration, requiring reboot to resume normal operation.
