THE THREAT
On February 23rd, 2021, VMware disclosed a critical vulnerability impacting vCenter Servers. The vulnerability, tracked as CVE-2021-21972, allows for remote code execution and if exploited, could result in the full compromise of affected systems. Abuse of this vulnerability does not require authentication or user interaction.
