Used method: Microsoft Internet Explorer (unpatched) contains a vulnerability that can allow script code within an HTML document to run an embedded executable file. Since the file is an HTML file, Internet Explorer will open and parse the file. When the script that points back to the embedded executable is parsed, the embedded executable will run on the client system in the security context of Internet Explorer. (Securityfocus)
