Adobe Flash content on numerous web sites contain input validation vulnerabilities. A remote user can conduct cross-site scripting attacks. [Editor’s note: This is not a vulnerability in Flash player.] Some Adobe Flash content (‘.swf’ files) may not properly filter HTML code from user-supplied input before displaying the input. A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user’s browser. The code will originate from the site hosting the Adobe Flash content and will run in the security context of that site. As a result, the code will be able to access the target user’s cookies (including authentication cookies), if any, associated with the site, 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.
