CVE-2014-3295: The HSRP implementation in Cisco NX-OS 6.2(2a) and earlier allows remote attackers to bypass authentication...

Security readout for executives and security teams

This flaw affects Cisco NX-OS HSRP handling in version 6.2(2a) and earlier. A remote attacker could bypass HSRP authentication with malformed packets and disrupt redundancy behavior, potentially causing traffic blackholing. Business impact is network availability, not data theft, based on the provided sources. Exposure is limited to environments running Cisco NX-OS 6.2(2a) or earlier where HSRP is enabled and reachable by an attacker capable of sending malformed HSRP packets. The bundle does not identify specific platforms beyond Cisco NX-OS. Handle as a network availability risk for legacy Cisco NX-OS environments. Prioritize if HSRP supports critical routing paths or high-availability designs, especially where affected devices are still in production. Mitigation focus: Check Cisco's security notice for affected platforms, fixed releases, and official remediation guidance.; Identify Cisco NX-OS devices at version 6.2(2a) or earlier that use HSRP.; Prioritize upgrade or replacement planning for affected HSRP-enabled devices..
