Author: Paul Affected Software: Mozilla Firefox 1.0.0, 1.0.1 (tested only on these versions) Risk: Low/Medium A minor security vulnerability exists in the way that Firefox handles cross-domain image dragging. 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 steal cookies, etc. A proof of concept is available at http://greyhatsecurity.org/vulntests/firefox.htm Vendor Reccomendations: Disable dragging images with javascript urls. User Reccomendations: Do not drag images into the address bar. Paul http://greyhatsecurity.org
