Plex


nmap discovered a plex Media Server running over HTTP on the target port 32400 i was also able to see the platinum upnp 1.0.5.13 service on the port 1184 and 32469 as it is used by plex Media Server

Webroot I got re-directed to a login page and it’s indeed the Plex Media Server

I tried some weak/default credentials and none of them worked. On top of that, there is a brute-force mitigation.

Sign-up Attempt


Sign-up is available. Creating a testing account

Upon clicking the button, I get this prompt. test is an existing username. I may be able to enumerate usernames through this error message

I will just create a user, test123

It says that it’s taken as well.

Upon attempting again, the web server now prompts a different error. There could be an issue within the web server itself or it may be due to the brute-force mitigation that I pointed out earlier.

I was finally able to sign-up

Logged in to the web application

I was able to get the PLEX version under setting tab However, enumerating the version did not give me any direction as it doesn’t have any known vulnerabilities
