EPSS (Exploit Prediction Scoring System) estimates a 13.6% chance this CVE is exploited in the wild within the next 30 days — higher than 96% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.
VMware Tools contains an authentication bypass vulnerability in the vgauth module. A fully compromised ESXi host can force VMware Tools to fail to authenticate host-to-guest operations, impacting the confidentiality and integrity of the guest virtual machine. An attacker must have root access over ESXi to exploit this vulnerability.
