Next up, Beep! The ping is running, the nmap is scanning! Lets have a look at this golden oldy!

Right off the bat, the sV and sC flag makes the scan time out or something. So just a simple nmap scan is what we fall back to.

A lot of ports! Going to port 80, it redirects to HTTPS, that seems to not support TLS1.2 or higher. Thats kinda interesting, i mean, its an older box. Perhaps i should try and see if i can get firefox to accept lower TLS versions. Changing the setting in about:config called security.tls.version.min to 1.

We now see the web-page:

Lets see if elastix has known vulnerabilities. There’s a couple on exploit-db. Lets try out a couple.
