I am forwarding this as it may impact people whom depend on MSN or
passport systems for business reasons. Contrary to what at
least one of the full-disclosure follow-ups reports, it does work.

Hotmail & Passport (.NET Accounts) Vulnerability

There is a very serious and stupid vulnerability or badcoding in Hotmail / 
Passport’s (.NET Accounts)

I tried sending emails several times to Hotmail / Passport contact addresses, 
but always met with the NLP bots.

I guess I don’t need to go in details of how cruical and important Hotmail / 
Passport’s .NET Account passport is to anyone.

You name it and they have it, E-Commerce, Credit Card processing, Personal 
Emails, Privacy Issues, Corporate Espionage, maybe stalkers and what not.

It is so simple that it is funny.

All you got to do is hit the following in your browser:

https://register.passport.net/emailpwdreset.srf?lc=1033&address@hidden&id=&cb=&address@hidden&rst=1

And you’ll get an email on address@hidden asking you to click on a url 
something like this:

http://register.passport.net/EmailPage.srf?EmailID=CD4DC30B34D9ABC6&URLNum=0&lc=1033

>From that url, you can reset the password and I don’t think I need to say 
>anything more about it.

Vulnerability / Flaw discovered         :       12th April 2003
Vendor / Owner notified         :       Yes (as far as emailing them more than 
10 times is concerned)

There are differing reports on the effectiveness of this attack. Our
testing here indicates that an older hotmail account is vulnerable, but a
newer one is not. It is unclear what the difference is, other than when
the account was created.
