Rackspace Technology is aware of an update to the previously published OpenSLP security vulnerability (CVE-2021-21974) impacting VMware ESXi. Our partner VMware published an article available here: https://blogs.vmware.com/security/2023/02/83330.html. When the vulnerability was first announced in February 2021, Rackspace engineers performed the initial assessment and notified affected customers if further action was needed. Rackspace standard VMware environments are designed with an architecture that prevents public access to VMware vCenters and Hypervisors – this design decreases the risk of exploitation of this vulnerability.

At Rackspace, we’ve enjoyed the many benefits VMware Cloud Director brings as it has allowed us to engineer a VMware-based cloud solution that delivers some amazing customer benefits once thought not possible on VMware. In this series over the next few weeks, I’ll provide an overview of some of the key features of VMware Cloud Director and our learnings. The series will cover the following topics so be sure to check back for new posts.
