VMware ESXi contains an authentication bypass vulnerability. A malicious actor with sufficient Active Directory (AD) permissions can gain full access to an ESXi host that was previously configured to use AD for user management https://blogs.vmware.com/vsphere/2012/09/joining-vsphere-hosts-to-active-directory.html by re-creating the configured AD group ('ESXi Admins' by default) after it was deleted from AD.

| CVE-2024-37085 | VMware ESXi Authentication Bypass Vulnerability | secondary_impact | T1608.001 | Upload Malware |
Comments
This vulnerability is exploited by an adversary who has already exploited an ESXi system and gained access to a valid account. Using this account, the adversary creates a new AD group named "ESXi Admins" that the ESXi Hypervisor grants full admin privileges. Adversary groups such as Storm-0506, Storm-1175, Octo Tempest, and Manatee Tempest have leveraged this vulnerability to deploy ransomware known as Akira and Black Basta onto compromised environments.
