Road to Pentester – INE Lab – Metasploit

Lab Intro

In this lab, you will have to use Metasploit and meterpreter against a real machine; this will help you become familiar with the Metasploit framework and its features.


I'm now in a network.

One host is alive.

Finger-print the host with nmap.

nmap -sC -sV -v

A lot of results.

Dance with port 21 a little first. It seems anonymous FTP login is allowed. Try connect.


Successfully logged in with anonymous:anonymous. But nothing can be found here.

Search for exploit with FreeFTPd 1.0.

searchsploit freeftpd 1.0

Found exploit that with metasploit.

Fire up metasploit and exploit. Let's use the 1 one.

Set the options.

Run the exploit.

No session was created... Try another the pass overflow one.

Set options.

Run it. Meterpreter session is opened.

Try getsystem.

Easy-peasy. Now I can do whatever I want with the system. Migrate to another pid.

s4u_persistence and registry_persistence not seem to work because of system requirements not met. Only persistence to try.

Set options.

Run it.

Restart the target and see if the backdoor works.

Open a handler to receive connection from the target.

Looks like the backdoor is working. It connects back to my machine.

Interact with the session.

Let's dump the hashes.

Crack it with jtr.

Now, last step. Search for a congrats.txt and download it as requested.

Let's explore if there's other options to exploit the machine.

Other ports don't seem to be vulnerable.

The lab's done. Time elapsed, 1 hour and 30 minutes.
