The concept is synonymous with how close you can get to 'system' where there is no additional abstraction.
A dinky example say is for instance you may need a password for X, but if you have access to disable the need for the password in X, you have lower level access. In the case at hand, with root level access you can read all the keys, passwords, settings in all the WP config files, otherwise you wouldn't be able to. You could also quietly add an additional password to the database allowing a bad application to run behind the scenes doing bad things with the data.
This makes for a very good simple CS test question.
