Synopsis

The remote VMware ESXi host is missing a security patch and is affected by multiple vulnerabilities.

Description

The remote VMware ESXi host is version 6.5, 6.7 or 7.0 and is affected by multiple vulnerabilities, including the following:

 - VMware ESXi, Workstation, and Fusion contain a use-after-free vulnerability in the XHCI USB controller. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host. (CVE-2021-22040)

 - VMware ESXi, Workstation, and Fusion contain a double-fetch vulnerability in the UHCI USB controller. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host. (CVE-2021-22041)

 - VMware ESXi contains an unauthorized access vulnerability due to VMX having access to settingsd authorization tickets. A malicious actor with privileges within the VMX process only, may be able to access settingsd service running as a high privileged user. (CVE-2021-22042)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Apply the appropriate patch as referenced in the vendor advisory.
