Article/Whitepaper: Bypassing JavaScript Filters - the Flash! Attack

"In this document we will be describing a loophole, with security implications, found in many websites that allow Flash documents to be inserted within HTML, or uploaded to the server. This paper relies on the fact that a huge number of web surfers have installed Macromedia Flash plugin/ActiveX control, for an attacker to launch a Cross-site scripting attack. We will not go into a lot of detail in describing Cross-site scripting attacks in general; However we hope that this paper will explain how Flash documents can be used to inject JavaScript into otherwise well filtered Web Applications."
