The ESXi host DCUI.Access list must be verified.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |
| V-258751 | ESXI-80-000189 | SV-258751r933314_rule | CCI-000366 | medium |
| Description | ||||
| Lockdown mode disables direct host access, requiring that administrators manage hosts from vCenter Server. However, if a host becomes isolated from vCenter, the administrator is locked out and can no longer manage the host. The "DCUI.Access" advanced setting allows specified users to exit lockdown mode in such a scenario. If the Direct Console User Interface (DCUI) is running in strict lockdown mode, this setting is ineffective. | ||||

Check Text (C-258751r933314_chk)
For environments that do not use vCenter server to manage ESXi, this is not applicable.
From the vSphere Client, go to Hosts and Clusters.
Select the ESXi Host >> Configure >> System >> Advanced System Settings.
Select the "DCUI.Access" value and verify only the root user is listed.
or
From a PowerCLI command prompt while connected to the ESXi host, run the following command:
Get-VMHost | Get-AdvancedSetting -Name DCUI.Access and verify it is set to root.
If the "DCUI.Access" is not restricted to "root", this is a finding.
Note: This list is only for local user accounts and should only contain the root user.

Select the ESXi Host >> Configure >> System >> Advanced System Settings.
Click "Edit". Select the "DCUI.Access" value and configure it to "root".
