Details

If revoked certificates are not removed from the vCenter Server, the user can be subject to a MiTM attack, which potentially might enable compromise through impersonation with the user’s credentials to the vCenter Server system.

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

Solution

If a site procedure to ensure the monitoring and removal of revoked certificates from the vCenter Server Windows host does not exist, create one. Check the vCenter Server/host for the presence of revoked certificates. Remove all revoked certificates.
