/*note: please tell me if "MSIE SP1" allows an internet page contains an

iframe with local content*/

[exp]

IFRAME in a page opened by "openModalDialog" has "dialogArguments" of its

parent. so Attacker can open (via "openModalDialog") his page which

contains an iframe whose content is in the victim zone and

uses "dialogArguments" directly without filtering.

in the demo:

(*)"victim zone" is localzone;

(*)the page from victim zone is "res://shdoclc.dll/privacypolicy.dlg"; it

uses "cookieUrl" without filtering.

[how]

realize that IFRAME has some properties the same as those of its parent.

but the parent can be bad.

(BTW, i used to hate that my parents give me many bad things, now i

realize it's my job to resist bad things. ;) )
