The license-installation module on the Cisco Nexus 1000V switch 4.2(1)SV1(5.2b) and earlier for VMware vSphere, Cisco Nexus 1000V switch 5.2(1)SM1(5.1) for Microsoft Hyper-V, and Cisco Virtual Security Gateway 4.2(1)VSG1(1) for Nexus 1000V switches allows local users to gain privileges and execute arbitrary commands via crafted "install all iso" arguments, aka Bug ID CSCui21340.

Security readout for executives and security teams

A local user on specific Cisco Nexus 1000V or Virtual Security Gateway versions could abuse the license installation function to escalate privileges and run arbitrary commands. The source bundle provides no CVSS score, no patch details, and no evidence of active exploitation. Exposure is most likely in legacy VMware vSphere, Microsoft Hyper-V, or Nexus 1000V environments still running the affected Cisco virtual switching or VSG versions. Treat as a targeted legacy-platform risk. Prioritize environments where local admin access is broad, shared, or weakly audited, especially if the virtual switch supports sensitive workloads. Mitigation focus: Inventory Cisco Nexus 1000V and Virtual Security Gateway deployments.; Compare deployed versions against the affected releases listed in the CVE.; Review Cisco’s advisory for supported fixed versions or compensating controls..
