Hi Richard,

AFAIK it can?t be done with a http://www.someserver./aux but there?re
several other ways to exploit this DoS. 

It can be done over network shares and anywhere we include HTML and
scripts (webpages, e-mails, internal documents and so on). I have
succesfully crashed a server placering a "COMn" reference in a special
folder. We had to remove the reference with a Windows 2000 bootdisk.

Other browsers are affected as well and at least two (of my knowledge)
are hit a lot harder than IE. They both cause the system to crash.

Med venlig hilsen // Kind regards

Emne: [Full-Disclosure] Does the Windows AUX bug affect Web servers
also?

Is it possible to also crash a Web server hosted on a Windows box using
a URL something like:

    http://www.somebody.com/aux

If this particular URL is okay, maybe there are other URLs that will
cause a crash.  For example, POSTing a form to a URL containing AUX.

This problem could be in any Windows Web server such as IIS, Apache,
ColdFusion, etc..

(I don't have access to a Windows Web server to try this out myself.)

Richard
