As you may have heard there have been some critical security alerts sent out from VMware in the last week. These are covering some privately reported vulnerabilities, not things seen out in the wild (yet). They affect all supported versions of vCenter and ESXi released before November/December 2020 and have a critical severity and index associated, some of the highest recorded yet.
There have been new versions of vCenter (6.5 U3n, 6.7 U3l and 7.0 U1c) released in Nov/Dec 2020 which aren’t affected and a patch released for ESXi (ESXi70U1c-17325551, ESXi670-202102401-SG and ESXi650-202102101-SG depending on ESXi version) which are recommended to be installed ASAP via Update Manager.
VMware has also documented workarounds for the vulnerabilities if these cannot be patched immediately. These workarounds disable the features of the products which are affected by the vulnerabilities. These are the vROPs plugin to vCenter (whether or not vROPS is being used) and the CIM hardware reporting in ESXi.
More information on the advisory and associated updated versions and workarounds can be found here – https://www.vmware.com/security/advisories/VMSA-2021-0002.html
As always with all VMware upgrades, please remember to check that your integrated product versions are compatible with the new versions before upgrading, especially with things such as VMware SRM and their 3rd party backup products.
