high Nessus Plugin ID 226454

Language:

Synopsis

The remote VMware ESXi host is affected by an information disclosure vulnerability.

Description

The version of VMware ESXi installed on the remote host is 7.0 prior to 7.0 Update 3s, 8.0 Update 2 prior to 8.0 Update 2d, or 8.0 Update 3 prior to 8.0 Update 3d. It is, therefore, affected by an information disclosure vulnerability:

 - VMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability due to an out-of-bounds read in HGFS. A malicious actor with administrative privileges to a virtual machine may be able to exploit this issue to leak memory from the vmx process. (CVE-2025-22226)


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

Solution

Upgrade to VMware ESXi 7.0 Update 3s, 8.0 Update 2d, or 8.0 Update 3d or later.
