Vulnerability from variot
The BGP implementation in Cisco NX-OS does not properly filter AS paths, which allows remote attackers to cause a denial of service (BGP service reset and resync) via a malformed UPDATE message, aka Bug ID CSCtn13055. The Cisco Nexus Series switches are data center switches. Adopt the Cisco Nexus OS operating system. Successful exploitation of the vulnerability allows the downstream peer to reset the BGP link of the affected device. Cisco NX-OS is prone to a denial-of-service vulnerability because it fails to properly sanitize user-supplied input. This issue is being tracked by Cisco bug ID CSCtn13055. The vulnerability is caused by the program not correctly filtering the AS path attribute value
