VAR-201503-0118

Vulnerability from variot - Updated: 2023-12-18 13:44

Cisco IOS 12.2, 12.4, 15.0, 15.2, and 15.3, when a VRF interface is configured, allows remote attackers to cause a denial of service (interface queue wedge) via crafted ICMPv4 packets, aka Bug ID CSCsi02145. Cisco IOS is a popular Internet operating system. Attackers can exploit this issue to cause the VRF interface on the device to enter a wedged state and stop processing packets, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCsi02145. The following releases are affected: Cisco IOS Release 12.2, Release 12.4, Release 15.0, Release 15.2, Release 15.3

Cisco IOS is a popular Internet operating system. \nAttackers can exploit this issue to cause the VRF interface on the device to enter a wedged state and stop processing packets, denying service to legitimate users. \nThis issue is being tracked by Cisco Bug ID CSCsi02145.
