Vulnerability assessment and exploitation

An authorised lab exercise covering the full chain of a penetration test

Authorised lab exercise: carried out on a lab target, never on a third-party system.

Context

An authorised exercise carried out in a lab, from a Kali Linux machine against a lab target.

It covers the full chain of a penetration test: reconnaissance, vulnerability identification and exploitation.

Architecture

The chain of a penetration test

Steps of the lab exercise Authorised lab environment Kali Linux attacker machine Step 1 Nmap Reconnaissance Open ports and running services Step 2 Samba Identification Vulnerable service, suitable exploit Step 3 Metasploit Exploitation usermap_script Step 4 Access Remote access obtained Lab target isolated, in the lab Samba Steps of the lab exercise Authorised lab environment Kali Linux attacker machine Step 1 Nmap Reconnaissance Open ports and running services Step 2 Samba Identification Vulnerable service, suitable exploit Step 3 Metasploit Exploitation usermap_script Step 4 Access Remote access obtained Lab target isolated, in the lab Samba
Inside the lab, the Kali Linux machine scans the target with Nmap, identifies a vulnerable Samba service, then uses Metasploit to exploit usermap_script and obtain remote access on the lab target.

What I did

  • Scanned the host with Nmap to identify open ports and running services.
  • Identified the vulnerable services and selected a suitable exploit.
  • Exploited the Samba usermap_script vulnerability with Metasploit to gain remote access on the lab target.
