Besides gaining local admin on vCenter, what other path can lead to obtaining the data.mdb file?
An attacker can acquire the `data.mdb` file from vCenter backup files. If backups are leaked, the same technique can extract the IdP certificate, create a SAML request, and gain admin access to the VCSA management panel. This enables interaction with managed virtual machines and can be combined with methods like the one described in [vSphere Development Guide 5 - LDAP](/news/vsphere-development-guide-5-ldap) for adding administrator users.
