No the code is not active, its part of a framework that will let you test the new exploit. The specific exploit that even the Department of Homeland Security warned all windows users to patch, is contained within the netapi_ms06_040 (download above), it is a .PM file and is a module for the Metasploit Framework. Or you could just run Metasploit and run an update.
All Hail Metasploit!! Don’t forget to install the latest version of the Metasploit Framework.
Now go out there and be somebody!!!!
