VCTR-67-000002 - The vCenter Server must not automatically refresh client sessions.

Information

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.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

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
