Notes

• 2021/12/10: Exploitation attempts in the wild of CVE-2021-44228 have been confirmed by VMware.
• 2021/12/11: A supplemental blog post & frequently asked questions list was created for additional clarification. Please see: <https://via.vmw.com/vmsa-2021-0028-faq&gt;
• 2021/12/13: Unaffected VMware products can be referred to on the Knowledge Base article: <https://kb.vmware.com/s/article/87068&gt;
• 2021/12/14: The Apache Software Foundation notified the community that their initial guidance for CVE-2021-44228 workarounds were not sufficient in removing all possible attack vectors. In addition, a new vulnerability identified by CVE-2021-45046 was published. In response, VMware has aligned with the new guidance and will be updating associated documentation with workarounds and fixes to address both vulnerabilities completely.
• 2021/12/17: The Apache Software Foundation updated the severity of CVE-2021-45046 to 9.0, in response we have aligned our advisory.
• 2022/01/07: A pair of new vulnerabilities identified by CVE-2021-45105 and CVE-2021-44832 have been disclosed by the Apache Software Foundation that impact log4j releases prior to 2.17.1 in non-default configurations. VMware has investigated and has found no evidence that these vulnerabilities are exploitable in VMware products. Going forward new log4j vulnerabilities will continue to be evaluated to determine severity and applicability to VMware products, but will not be referenced in this advisory. VMware products will update open source components (including log4j) to the latest available versions in future releases.
