## Information Gathering

`sudo ./nmapAutomator.sh 192.168.163.47 all`

### Service Enumeration

### HTTP (Port 80)

Looks like a blank website used for testing.

Doesn't look like there's anything else here that could be useful.

### Postgresql (Port 5437)

Since we know the default username is `postgres`, we can try the default password as well, `postgres`, and we managed to log in.

Since this version of `postgresql` is higher than 9.3 and we are super user, we can run the following exploit.

## Exploit

Let's use Metasploit for this exploit to make life easier.

And we got an interactive shell!

## Privesc

Running LinEnum on the target machine, we find an interesting SUID file.

Searching on GTFObins and we got the exact command needed.
