The self-extracting installer in the vSphere Client Installer package in VMware vCenter 4.0 before Update 3 and 4.1 before Update 1, VMware ESXi 4.x before 4.1 Update 1, and VMware ESX 4.x before 4.1 Update 1 does not have a digital signature, which might make it easier for remote attackers to spoof the software distribution via a Trojan horse installer.

Security readout for executives and security teams

This CVE is about trust in VMware installer distribution. Older vCenter, ESXi, and ESX 4.x packages included a self-extracting vSphere Client installer without a digital signature, making spoofed or Trojanized installers harder for users to detect. Exposure is mainly legacy VMware environments that still host, distribute, or use affected vSphere Client installer packages from vCenter, ESXi, or ESX 4.x systems. Treat as a legacy virtualization hygiene issue with supply-chain implications. Prioritize if old VMware 4.x infrastructure or archived installers remain accessible to administrators. Mitigation focus: Upgrade vCenter 4.0 to Update 3 or later.; Upgrade vCenter 4.1 to Update 1 or later.; Upgrade ESXi or ESX 4.x to 4.1 Update 1 or later..
