  Cross Site Scripting in Mozilla Firefox
------------------------------------------------------------------------


SUMMARY

 <http://www.mozilla.org/> Firefox is "a fast, full-featured browser that 
makes browsing more efficient than ever before .

Firefox contains a security vulnerability in the way how it handles 
cross-domain image dragging, allowing a remote attacker to cause it to 
execute arbitrary JavaScript.

DETAILS

Vulnerable Systems:
 * Mozilla Firefox version 1.0.1
 * Mozilla Firefox version 1.0

Dragging an image into the address bar will cause Firefox to navigate to 
the image URL even if it is a JavaScript URL and the page to be navigated 
from is in a different domain than the page on which the image is shown. 
This may potentially allow attackers to preform a cross site scripting 
attack.

Proof of Concept:
<img src="javascript:alert(location.href)">

A working example of the problem can be located at
