Green Cloud was notified of the VMware VMSA-2021-0002 security advisory at publication and immediately began preparations to remediate the vulnerability. The critical advisory for CVE-2021-21972 is related to the vCenter Server plugin for vROPs and requires network access on port 443. By design, Green Cloud's vCenter servers are not externally exposed in any way and are heavily protected by multiple layers of security.
Beginning Tuesday March 2nd at midnight and continuing each night through Friday morning at 5am, during our maintenance hours of 12am to 6am EST, Green Cloud will be performing the necessary infrastructure patching required to remediate this vulnerability. There is no expected impact to running VMs during this process, but administrative access via vCloud will be impacted during service restart intervals.
