## Description

Microsoft Internet Explorer 9 and earlier does not properly restrict cross-zone drag-and-drop actions, which allows user-assisted remote attackers to read cookie files via vectors involving an IFRAME element with a SRC attribute containing an http: URL that redirects to a file: URL, as demonstrated by a Facebook game, related to a "cookiejacking" issue, aka "Drag and Drop Information Disclosure Vulnerability." NOTE: this vulnerability exists because of an incomplete fix in the Internet Explorer 9 release.
