Critical VMware vCenter Vulnerability

THE THREAT

On September 21st, VMware announced a critical vulnerability impacting VMware vCenter servers. The vulnerability is a file upload vulnerability tracked as CVE-2021-22005 (CVSS: 9.8). Exploitation would allow a threat actor to execute remote code on vulnerable systems by uploading a specially crafted malicious file. Previous authentication is not required for exploitation.

Organizations are strongly recommended to apply the relevant security patch as soon as possible. Exploitation has not been identified in the wild at this time but is expected in the near future.

Additional information

CVE-2021-22005 impacts vCenter Server 6.7 and 7.0. Exploitation requires that a vulnerable version of vCenter be accessible over port 443. While exploitation has not been publicly identified at this time, it is expected in the near future. CVE-2021-22005 is considered trivial to exploit and would provide significant access to threat actors; these factors increase the likelihood that threat actors will focus on this vulnerability, and attempt to exploit it before organizations have widely deployed patches.

In addition to CVE-2021-22005, VMware addressed 18 other vulnerabilities. These vulnerabilities are not considered critical but should be addressed with the available security patches.
