Overview
VMware Tools is a guest-OS integration suite accompanying VMware virtualization products (e.g., vSphere) that provides drivers, services, and other utilities to improve performance, manageability, and interoperability between the guest OS and the virtualized host. Its components are critical for optimal VM operation, and vulnerabilities in VMware Tools can be exploited to compromise virtual machines or escalate access, making timely patching essential in VMware environments. Recent disclosures placing VMware Tools flaws in the U.S. CISA Known Exploited Vulnerabilities catalog underscore its significance as an attack surface in cybersecurity.
