READY, SCAN, ATTACK!!!
First, we will find a target and ensure the host is up. We will do this by using Nmap:
#nmap -sn 192.168.71.156
Once we know the host is up and running, we will use Nmap to find any critical vulnerabilities. We invoke the command
#nmap --script vuln 192.168.71.156 --reason
With this command, Nmap will execute the NSE script called Vuln and scan the host for vulnerabilities. Once the scan completed, we can see the result and show the available vulnerability of the host. The result even provide us with the link to know more information of the vulnerability.
