TITLE:
Opera Image Dragging Vulnerability

SECUNIA ADVISORY ID:
SA15756

VERIFY ADVISORY:
http://secunia.com/advisories/15756/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Opera 8.x
http://secunia.com/product/4932/

DESCRIPTION:
Secunia Research has discovered a vulnerability in Opera, which can
be exploited by malicious people to conduct cross-site scripting
attacks and retrieve a user's files.

The vulnerability is caused due to Opera allowing a user to drag e.g.
an image, which is actually a "javascript:" URI, resulting in
cross-site scripting if dropped over another site. This may also be
used to populate a file upload form, resulting in uploading of
arbitrary files to a malicious web site.

Successful exploitation requires that the user is tricked into
dragging and dropping e.g. an image or a link.

The vulnerability has been confirmed in version 8.01. Prior versions
may also be affected.

SOLUTION:
Update to version 8.02.
