Metasploit Penetration Testing Cookbook - Third Edition

By: Daniel Teixeira, Abhinav Singh, Nipun Jaswal, Monika Agarwal

Overview of this book

Metasploit is the world's leading penetration testing tool and helps security and IT professionals find, exploit, and validate vulnerabilities. Metasploit allows penetration testing automation, password auditing, web application scanning, social engineering, post exploitation, evidence collection, and reporting. Metasploit's integration with InsightVM (or Nexpose), Nessus, OpenVas, and other vulnerability scanners provides a validation solution that simplifies vulnerability prioritization and remediation reporting. Teams can collaborate in Metasploit and present their findings in consolidated reports. In this book, you will go through great recipes that will allow you to start using Metasploit effectively. With an ever increasing level of complexity, and covering everything from the fundamentals to more advanced features in Metasploit, this book is not just for beginners but also for professionals keen to master this awesome tool. You will begin by building your lab environment, setting up Metasploit, and learning how to perform intelligence gathering, threat modeling, vulnerability analysis, exploitation, and post exploitation—all inside Metasploit. You will learn how to create and customize payloads to evade anti-virus software and bypass an organization's defenses, exploit server vulnerabilities, attack client systems, compromise mobile phones, automate post exploitation, install backdoors, run keyloggers, highjack webcams, port public exploits to the framework, create your own modules, and much more.

Exploiting a Linux server


Linux is one of the most widely used operating systems. In the previous few recipes, we saw how to scan for available services and use vulnerability scanners to find vulnerabilities. In this recipe, we will deal with Linux operating systems. We will be using the Metasploitable 2, for our vulnerable Linux machine in this recipe, but the process will be similar for exploiting any flavor of Linux and Solaris running the Samba service. Let's move ahead with the recipe.

Getting ready

  1. First, will use the services command to display the results from our previous nmap scan and filter for ports 139 and 445:
msf > services -c port,info -p 139,445 192.168.216.129

Services

host             port  info

192.168.216.129  139   Samba smbd 3.X - 4.X workgroup: WORKGROUP
192.168.216.129  445   Samba smbd 3.0.20-Debian workgroup: WORKGROUP

  1. Now that we know the version of the Samba daemon running, we can search for vulnerabilities and...
