The flaw cannot be fixed and the only solution is to introduce and use
Microsoft's Credential Guard program to prevent passwords from being stored
in memory, according to his extensive blog post.

The flaw results from how the third-party authentication system creates
secret keys: by using the password associated with a disabled username
(krbtgt). That password is rarely changed, making it possible to bypass the
authentication system altogether and allow an attacker to grant themselves
admin privileges, as well as create secret passwords for existing users and
new users that don't exist.

Although some of the entry points are time-limited – the system will seek
to validate accounts after 20 minutes – because it is possible to create
fake users without limit, it is possible to access a system incessantly.
