Pentest lab - Metasploitable 2

Today I will walk through different ways of exploiting Metasploitable 2, the newer release of Rapid7’s popular vulnerable machine. First, what is Metasploitable? Metasploitable is an intentionally vulnerable Linux virtual machine. This VM can be used to conduct security training, test security tools, and practice common penetration testing techniques. In my lab environment, the IP of the attacker machine is 192.168.127.159, and the victim machine is 192.168.127.154. Since this is a test lab, I won’t be concerned about stealth. Instead, I will try to get the most information out of the scans. Let’s start by port scanning the target with nmap. I did a full port, aggresive scan against the target. Here are the results. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 ...

Metasploitable 2 vulnerability assessment

A vulnerability assessment is a crucial part in every penetration test and is the process of identifying and assessing vulnerabilities on a target system. In this part of the tutorial we will be assessing the vulnerabilities available on the network side of the Metasploitable 2 virtual machine. We will be assessing the web applications on the Metasploitable 2 machine in a later tutorial. In the previous Metasploit enumeration and fingerprinting tutorial we’ve learned that the Metasploitable 2 machine contains a lot of vulnerabilities. We have collected valuable information about the target system which we will be using to find known vulnerabilities both on- and offline. Exploitation of these vulnerabilities will be demonstrated in the next exploitation tutorial. In this tutorial we will be looking at a few different ways to perform vulnerability analysis. We will be manually searching for exploits, use scanning tools like Nmap with scripts and we will be...

CEH v9 (CEHVIETNAM.COM) - Hacking Metasploitable Lab

CEH v9 : Hacking Metasploitable VM In this guide, I will demonstrate how to root a Metasploitable 2 virtual machine. Metasploitable is an intentionally vulnerable Ubuntu machine. I’ll explore just a few of the many ways Metasploitable can be attacked, from vulnerabilities in common services to little known exploits and web vulnerabilities. I’ve set up Kali Linux and Metasploitable VMs in VirtualBox on the same network (bridged mode).
