VMware vSphere 6.7 vCenter STIG:
VCTR-67-000002
(in versions v1 r3 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 Windows, this is not applicable. On the vCenter Server, execute the following command: # grep "^refresh\.rate" /etc/vmware/vsphere-client/webclient.properties Expected result: refresh.rate = -1 If the output does not match the expected result, this is a finding.
Fix Text
Navigate to and open /etc/vmware/vsphere-ui/webclient.properties. Remove any existing "refresh.rate" line and add the following: refresh.rate = -1 After editing the file, the vSphere Client service must be restarted. # service-control --restart vsphere-client
