Description
If a user forgets to log out of their local or remote ESXi Shell session, the idle connection will remain open indefinitely and increase the likelihood of inappropriate host access via session hijacking. The "ESXiShellInteractiveTimeOut" allows the automatic termination of idle shell sessions. Satisfies: SRG-OS-000163-VMM-000700, SRG-OS-000279-VMM-001010

From the vSphere Client, go to Hosts and Clusters. Select the ESXi Host >> Configure >> System >> Advanced System Settings. Select the "UserVars.ESXiShellInteractiveTimeOut" value and verify it is set to "900" or less and not "0". or From a PowerCLI command prompt while connected to the ESXi host, run the following command: Get-VMHost | Get-AdvancedSetting -Name UserVars.ESXiShellInteractiveTimeOut If the "UserVars.ESXiShellInteractiveTimeOut" setting is set to a value greater than "900" or "0", this is a finding.
