VAR-200112-0002

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

Cisco 12000 with IOS 12.0 and line cards based on Engine 2 does not properly handle the implicit "deny ip any any" rule in an outgoing ACL when the ACL contains exactly 448 entries, which can allow some outgoing packets to bypass access restrictions. Cisco 12000 Series Internet Routers with line cards based on Engine 2 are prone to an unusual issue where they may fail to drop packets. The result is that some packets will not be dropped, potentially allowing restricted traffic into the network. Cisco has assigned Vulnerability CSCdu03323 to this issue. Some outgoing packets bypass access restrictions
