IE cookie menagment and CSRF

Subject: IE cookie menagment and CSRF
Date: Fri, 20 Aug 2004 16:04:25 +0200
Hi All,

Recently while toying with CSRF XSS I found out that when I place sth. like
<img src=âdomainB/logout.phpâ> on domainA IE(6.0.2800.1106.xpsp2.030422-1633) sends cookies from siteB. and Mozilla 1.7.2 don't.
Thins means that some web page on domainA can force any GET request as previously authorized user on domainB.


(imaginary scenario)
1)user logs on e-bay
2)wants to buy a book from attacker
3)attacker makes a webpage âSee what I sell on ebayâ with <img src=âhttp://ebay.com/bid.cgi?item=34345&price=99999â;> and links it to the auction
4)when user views his page he not wilingly bids 999999$ on an item


I think that Mozilla does right not sending cookies because domains of the cookies should apply to originating html document if it's an image not a link. Am i right ?

What do You thing about it ? Is it a bug or it's ok and we should use only POST methods for important forms?
