Check: VCTR-67-000070
VMware vSphere 6.7 vCenter STIG:
VCTR-67-000070
(in versions v1 r4 through v1 r1)
Title
The vCenter Server must not automatically refresh client sessions. (Cat II impact)
Discussion
Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port that has been left unattended. In addition, quickly terminating an idle session will also free up resources committed by the managed network element. Automatic client session refreshes keep unused sessions online, blocking session timeouts.
Check Content
Note: For vCenter Server Appliance, this is not applicable. On the vCenter Server locate the "webclient.properties" file in C:\ProgramData\VMware\vCenterServer\cfg\vsphere-client Find the "refresh.rate =" line in the "webclient.properties" file. If the refresh rate is not set to "-1" in the "webclient.properties" file, this is a finding.
Fix Text
Change the refresh rate value by editing the "webclient.properties" file. On the vCenter Server locate the "webclient.properties" file in C:\ProgramData\VMware\vCenterServer\cfg\vsphere-client Edit the file to include the line "refresh.rate = -1" where "-1" indicates sessions are not automatically refreshed. Uncomment the line if necessary. After editing the file the vSphere Client service must be restarted.
