CVE-2007-5671: HGFS.sys in the VMware Tools package in VMware Workstation 5.x before 5.5.6 build 80404, VMware Player befo...

Security readout for executives and security teams

This is an old VMware Tools local privilege escalation issue. A user already inside an affected guest operating system could abuse the HGFS driver to gain higher privileges in that guest. It is not described as a remote internet attack, but it matters where legacy VMware products or old Tools builds remain in use. Exposure is most likely in legacy virtualized environments running the listed VMware product versions with the affected VMware Tools HGFS.sys driver present in guest systems. The provided data does not identify affected CPEs or modern product lines. Treat as high priority for legacy VMware estates, especially where untrusted users or workloads run inside guests. Modern environments may have no exposure, but unmanaged old VMware Tools builds create avoidable privilege escalation risk. Mitigation focus: Upgrade affected VMware products and Tools to the fixed builds named in the CVE record.; Prioritize VMware Workstation 5.x, Player before 1.0.6, ACE, Server, and ESX 2.5.4 through 3.0.2.; Check VMware advisory VMSA-2008-0009 for product-specific update guidance..
