解决方法和缓解措施

PowerFlex Appliance includes the updated vCenter versions containing the remediation in an upcoming release update. In the meantime, the following workaround is recommended for PowerFlex Appliance customers.

VMware’s recommended workaround is to temporarily disable the “VMware vSAN H5 client plug-in” for vCenter Server.

The procedure to disable the plug-in is outlined in the VMware KB article: https://kb.vmware.com/s/article/83829

Note:

  • The workaround is expected to be a temporary mitigation until the updated release is available.
  • Changes in the workaround must be reverted after applying the vCenter update. Procedure to revert the changes is outlined in https://kb.vmware.com/s/article/83829.
  • vSAN continues to function as expected, and vSAN related alarms continue to trigger for any events in the environment. These features are not dependent on the vSAN H5 plug-in.
  • The vSAN sections in the Monitoring and Configuration tabs in the vCenter UI are unavailable, and thus you cannot change the existing vSAN configuration.
  • The Skyline/vSAN Health UI interface is unavailable but the underlying logic monitoring the environment is still functional.
  • If there is a critical issue with vSAN, then the plug-in may need to be temporarily enabled to assist with troubleshooting and quicker resolution. When the issue is addressed, the plug-in can be disabled again. In this scenario, vCenter is exposed to the vulnerability as described in VMSA-2021-0010 while the plug-in is enabled.
