Flash Origin Policy Issues
Flash objects run scripts in the origin they are served from, and a SWF needs no .swf extension or content-type to execute, so any site serving user-uploaded files from its own domain is exploitable. Content overloading — the inverse of GIFAR — prepends a SWF to any ZIP-family file, defeating validation. Demonstrated against cPanel, SquirrelMail and Gmail attachments.
