Security readout for executives and security teams

CVE-2013-1406 is a local privilege escalation issue in VMware VMCI components. A user who already has local access to an affected system may be able to gain higher privileges. The sources name older VMware Workstation, Fusion, View, ESXi, and ESX versions. There is no cited evidence of active exploitation. Exposure is most likely in legacy VMware deployments, especially unsupported Workstation, Fusion, View, ESXi, or ESX installations. Modern environments should still verify inventories because old hypervisors and administrator workstations often persist outside normal patch programs. Prioritize remediation where affected VMware systems host sensitive workloads or support administrator activity. The issue requires local access, but privilege escalation on virtualization infrastructure can materially increase business impact. Treat legacy ESX and ESXi findings as higher urgency. Mitigation focus: Identify affected VMware Workstation, Fusion, View, ESXi, and ESX versions.; Upgrade Workstation, Fusion, and View to the fixed versions named in the CVE description.; Consult VMware VMSA-2013-0002 for exact ESX and ESXi remediation guidance..
