ClarkConnect XSS vulnerability in latest version 5.0. Proof of concept through unsanitized 'url' GET variable in proxy.php.

Code
`Hello,  
  
I have found an XSS vulnerability in ClarkConnect web interface.  
ClarkConnect is an internet server and gateway that provides protocol filtering, bandwidth management, Windows File Sharing / Samba, LDAP Directory Integration and other features...  
The vulnerability was found in the latest version of this product (5.0).  
ClarkConnect installs a Web server on port 82 to process the PHP scripts it uses for configuration.  
  
Proof of concept:  
http://server_address:82/public/proxy.php?url=<script>alert("XSS")</script>  
  
Obviously, the 'url' GET variable is not well sanitized.  
  
Best regards,
