Denial of Service Vulnerability in Cisco CSS 11000 Routers by Cisco

CVE-2003-0677

Summary

The Cisco CSS 11000 routers, specifically those on the CS800 chassis, can be exploited by remote attackers who send a high volume of TCP SYN packets directed at the circuit IP address. This excessive traffic can lead to significant CPU consumption or even cause the router to reboot, disrupting services and affecting network stability. Administrators are advised to implement monitoring and rate-limiting measures to mitigate the potential impact of this vulnerability.
