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.
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error.
