X11 - access denied pivot point

Good Day!

I have downloaded a Metasploitable 2 machine wherein i am currently on the port 6000 - x11. I have tried to search for an exploit locally but all of these are for unauthenticated access as well on sites. i tried to find as well it’s display manager configuration and done a xhost + command but the result given was still the same after following up on the nmap. may i kindly ask for help/tips on a starting point on this service.

Thank you!
