Security readout for executives and security teams
This flaw affects older VMware vSphere Client versions. A remote vCenter Server or ESXi instance could abuse XML processing to make the client read arbitrary files from the administrator’s workstation. Business risk depends on whether legacy vSphere Client 5.5 or 6.0 clients still connect to remote or untrusted infrastructure. Exposure is most likely where administrators still use vSphere Client 5.5 before U3e or 6.0 before U2a. The affected surface is the client-side management workstation interacting with vCenter Server or ESXi, not every VMware deployment by default. Treat as a targeted legacy VMware administration risk. Prioritize if old vSphere Client software remains on administrator workstations, especially where those clients connect to externally managed, partner-managed, or otherwise less-trusted vCenter or ESXi systems. Mitigation focus: Upgrade vSphere Client 5.5 to U3e or later.; Upgrade vSphere Client 6.0 to U2a or later.; Review VMware VMSA-2016-0022 for vendor-approved remediation guidance..
