VAR-200112-0062

Vulnerability from variot - Updated: 2025-04-03 22:16

Cisco 12000 with IOS 12.0 and line cards based on Engine 2 and earlier allows remote attackers to cause a denial of service (CPU consumption) by flooding the router with traffic that generates a large number of ICMP Unreachable replies. Cisco 12000 When using a black hole filter in a series internet router, ICMP Service disruption when a large number of unreachable packets are sent (DoS) There is a vulnerability that becomes a condition.ICMP Service operation disruption by sending a large number of unreachable packets (DoS) There is a possibility of being in a state. Cisco 12000 Series Internet Routers are prone to a denial of service condition. Successful exploitation may cause the router to stop forwarding packets. This condition may occur when the router is "Black Hole" filtering. It should be noted that this vulnerability only affects certain Cisco 12000 Series Internet Routers, and other Cisco router products should not be considered vulnerable. Cisco classifies this issue under Vulnerability CSCdr46528, Vulnerability CSCds36541 and Vulnerability CSCdt66560. Engine 2 based Cisco 12000 with IOS 12.0 and line cards and earlier versions are vulnerable
