Details

Disable unexposed GetCreds feature.

*Rationale*

Some VMX parameters don’t apply on vSphere because VMware virtual machines work on

vSphere and hosted virtualization platforms such as Workstation and Fusion. The code

paths for these features are not implemented in ESXi. Explicitly disabling these features

reduces the potential for vulnerabilities because it reduces the number of ways in which a

guest can affect the host. Note that these are referenced for organizations that insist any

documented setting, regardless of whether it is implemented in code or not, must have a

value.

Solution

To implement the recommended configuration state, run the following PowerCLI
command-# Add the setting to all VMs
Get-VM | New-AdvancedSetting -Name ‘isolation.tools.getCreds.disable’ -value $true

Impact-Some automated tools and process may cease to function.

Default Value-The prescribed state is not the default state.
