Since yahoo isn't known for fixing bugs fast unless it's serious (and
even then), here's something i wrote up today.
The exploit is turned into a script-kiddish interface. Here's how it
works:
1) you enter your email and the target (@yahoo.com) email
2) an email with the exploit is sent to the target
3) when the target opens the mail for reading, cookies get stolen and
you get a notification on the address specified
4) further instructions on how to log in are on the site.
 
Tested on IExplore and Opera, works with both.

(I'm taking it down when yahoo fixes it or people abuse it too much)
