Description:   A vulnerability was reported in Opera. A remote user can conduct cross-site scripting attacks. A remote user can also access files on the target user's system.

A remote user can create an image (or other object) that is a 'javascript:' URI. When the object is dragged by the target user to another site, the scripting code may be executed in the context of the other site. The scripting code can automatically execute a file upload form to upload files from the target user's system to a remote site.

The target user must drag the object to trigger this vulnerability.

Jakob Balle of Secunia Research discovered this vulnerability.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the target site (to which the malicious object is dragged by the target user), access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
Solution:   The vendor has issued a fixed version (8.02), available at:
