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
