Looking at the vulnerability scan I can see that this system is vulnerable smb ms17-010
Exploitation:
I’m choosing to use Metasploit to attack this machine. I go to search for ms17-010:
Sure enough Metasploit confirmed that this machine is vulnerable to smb:
Going back to our scan notes, I noticed that system I’m trying to access is Windows XP.
So going back to Metasploit I choose the exploit netapi:
Internal System Gathering:
We have SYSTEM which for windows that is root level.
