: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&am!
p;em=modulohio () hotmail com&id=&cb=&prefem=li_crvgjur1 () hotmail 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)

I assume you used security () microsoft com ? And you have found this
since 2003 and wanted to tell someone. Lame excuse dude. If e-mail
fails (which is unlikely if you use the correct address, which isnt
hard to find via search engines) then you can -easily- phone up
microsoft and make them aware and ask to be redirected to the security
team, or ask the switch board for the correct e-mail or the e-mail of
an employee. I'm sorry but it didn't wash that you tried every avenue
of contact before disclosing this vulnerability a year later, via a
security mailing list.

It sounds more like a kids excuse for smashing a window or getting
caught stealing candy from a store.

Further remarks on this are welcome...
