Description

This module bypasses LDAP authentication in VMware vCenter Server's vmdir service to add an arbitrary administrator user. Version 6.7 prior to the 6.7U3f update is vulnerable, only if upgraded from a previous release line, such as 6.0 or 6.5. Note that it is also possible to provide a bind username and password to authenticate if the target is not vulnerable. It will add an arbitrary administrator user the same way.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
