Is there a metasploitable 2 exploitability guide?
Metasploitable 2 Exploitability Guide The Metasploitable virtual machine is an intentionally vulnerable version of Ubuntu Linux designed for testing security tools and demonstrating common vulnerabilities. Version 2 of this virtual machine is available for download and ships with even more vulnerabilities than the original image.
Where is the IP address of metasploitable 2?
This means that Metasploitable must have an IP residing somewhere in the 192.168.154.xxx range. To scan all ports in that range, you can use Nmap scan. Here is what it should look like. Host is up (0.00084s latency). The conclusion that can be drawn here is that the Metasploitable 2 machine has IP 192.168.154.132.
What are the ports of metasploitable 2 vulnerability?
The 512,513 and 514 ports are there for remotely accessing Unix machines. They have been misconfigured in such a way that anyone can set up a remote connection without proper authentication. This vulnerability is easy to exploit. We will use rlogin to remotely login to Metasploitable 2.
How to identify open network services in metasploitable 2?
After the virtual machine boots, login to console with username msfadmin and password msfadmin. From the shell, run the ifconfig command to identify the IP address. From our attack system (Linux, preferably something like Kali Linux), we will identify the open network services on this virtual machine using the Nmap Security Scanner.
