VAR-201311-0306
Vulnerability from variot - Updated: 2025-04-11 23:15Cisco NX-OS 5.0 and earlier on MDS 9000 devices allows remote attackers to cause a denial of service (supervisor CPU consumption) via Authentication Header (AH) authentication in a Virtual Router Redundancy Protocol (VRRP) frame, aka Bug ID CSCte27874. Cisco MDS 9000 Runs on the device Cisco NX-OS There is a service disruption ( Supervisor CPU Resource consumption ) There are vulnerabilities that are put into a state. Cisco MDS 9000 NX-OS Software is prone to a remote denial-of-service vulnerability. Attackers can exploit this issue to cause the device to consume excessive CPU resources, resulting in denial-of-service conditions. This issue is being tracked by Cisco bug ID CSCte27874. Cisco NX-OS is a data center-oriented operating system developed by Cisco. The vulnerability is caused by the program not correctly handling Virtual Router Redundancy Protocol (VRRP) packets
