I'd point out to the customer that there are ways to brute-force the
username and password. If someone were to find a legitimate username
and password by brute-force, then they could exploit whatever holes
his IIS installation has - Unicode or otherwise.

(You'll find a HTTP-Auth brute-forcer program called ObiWaN at
http://www.phenoelit.de/obiwan/)

Subject: IIS/Unicode and authentication box

I am trying to show to a customer that his IIS server is vulnerable
to unicode exploits. However, access to his server is password
protected
(Require valid-user) I get "HTTP/1.1 401 Access Denied" and
"You are not authorized to view this page".

As far as I am concerned, having password box does mean he does
not have to patch his web server. How can I show that his box
is vulnerable? Anybody?
