TITLE

Cisco NX-OS Software HSRP Packet Parsing Denial of Service Vulnerability

Trust: 0.9

sources: CNVD: CNVD-2014-03704 // BID: 67983

DESCRIPTION

The HSRP implementation in Cisco NX-OS 6.2(2a) and earlier allows remote attackers to bypass authentication and cause a denial of service (group-member state modification and traffic blackholing) via malformed HSRP packets, aka Bug ID CSCup11309. Vendors have confirmed this vulnerability Bug ID CSCup11309 It is released as.Malformed by a third party HSRP Authentication is avoided and service operation is interrupted via packets. ( Group member state changes and traffic black holes ) There is a possibility of being put into a state. Cisco NX-OS is a data center-level operating system. An attacker could exploit this vulnerability to bypass authentication and convert the status of a group member to SPEAK, causing a denial of service. An attacker can leverage this issue to cause a denial-of-service condition; denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCup11309
