orDialog-MyPage.htm
or
clik.to/liudieyu ==> PoisonousSTYLEforDialog-MyPage section.

[exp]
you can appoint the style of text in window(a "ModalDialog" window) opened
by "showModalDialog()" regardless of zone difference.

the style can cause execution of script, one example:
<IMG width="0" height="0" style="width: expression(alert());">

so "poisonous" style can do XSS at client side.

that's all

[how]
i spent some time trying to bypass hotmail script filtering, so i read
something about it, including the above one from Guninski.
so, i got this one as soon as i read the description of "showModalDialog
()" at MSDN.

[BTW]
if you are interested in XSS at server side, don't miss a tool at
