Microsoft Word, Excel, and Powerpoint 2007 contain a remote code execution vulnerability because it is possible to reference documents such as Works document (.wps) as HTML. It will process HTML and script code in the context of the local machine zone of Internet Explorer which leads to arbitrary code execution. By persuading users into opening eg. specially crafted .WPS, “.doc “, “.RTF ” (with a space at the end) it is possible to trigger the vulnerability and run arbitrary code in the context of the logged on Windows user.
