Exploiting this kind of vulnerability is very simple.All you have to do is start metasploit framework and send the required payload to the target system.
I am assuming that you already have nmap scanned your target machine.These are my scan results : You can see that nmap points out that specified machine is vulnerable to ms 17–010
Nmap scan report for 10.10.57.27
