    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=elartemuebles@hotmail.com&id=&cb=&prefem=esteramoni@hotmail.com&rst=1

    And you’ll get an email on esteramoni@hotmail.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)
