The encryption functionality in the Virtual Supervisor Module (VSM) to Virtual Ethernet Module (VEM) communication component in Cisco NX-OS on the Nexus 1000V does not properly authenticate VSM/VEM packets, which allows remote attackers to disable packet-level encryption and integrity protection via crafted packets, aka Bug ID CSCud14710.

Security readout for executives and security teams

This weakness could let an attacker tamper with protection between Cisco Nexus 1000V VSM and VEM components, disabling packet-level encryption and integrity checks. It is mainly relevant to legacy Nexus 1000V environments. Exposure appears limited to organizations still operating Cisco Nexus 1000V with VSM/VEM communication. The source bundle does not provide affected versions, CPEs, or deployment prerequisites. Treat this as a legacy infrastructure risk requiring inventory first. Urgency increases if Nexus 1000V remains in production or control-plane communication is broadly reachable. Mitigation focus: Check Cisco advisory guidance for fixed releases or workarounds.; Inventory any Cisco Nexus 1000V deployments and NX-OS versions.; Prioritize remediation where VSM/VEM communication is reachable from untrusted networks..
