Looking at this list it seems to affect mostly older versions of windows servers and servers with SMB running. I'd say it would mostly be a problem on intranets than windows based web servers.
Which is going to be Domain Controllers, the most highly privileged servers on most corporate networks. And accessible to the "entire" network too. Group Policy is distributed through SMB shares.
Both tools in the demo video are SMB-based. I wonder how exploitable is a machine if it has SMB properly disabled and blocked.
