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.
Weakness
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
