CVE-2013-6683

TITLE

Cisco NX-OS of IPv6 Service disruption in implementations (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2013-005109

DESCRIPTION

The IPv6 implementation in Cisco NX-OS does not properly handle neighbor-table adjacencies, which allows remote attackers to cause a denial of service (NS processing outage) via a series of malformed packets, aka Bug ID CSCtd15904. The Cisco Nexus Series switches are data center switches. Adopt the Cisco Nexus OS operating system. A denial of service vulnerability exists in the Cisco NX-OS Software for Nexus 4000 Series. Successful exploits may cause the device to stop responding to NS requests, resulting in denial-of-service conditions. This issue is being tracked by Cisco bug ID CSCtd15904. There is a security loophole in the IPv6 implementation process in Cisco NX-OS software. The loophole is caused by the program not correctly handling the connection relationship of the neighbor table
