Advisory Information:
===================================
Persistent XSS, LFI & Open Redirect



Vulnerability Details:
======================

Persistent XSS:
---------------
Users can inject XSS payloads that will be saved to MySQL DB, where they will execute each time when accessed.

1- In Admin under 'Media Center' users can inject XSS payloads and save to the 'media_title' field for a saved media file,
   create a new media page inject payload click save and then select visualize. 

2- Under Website menus area users can inject XSS payloads and save for the 'menu_title' field for a Website menu.

If we view browser source code at http://localhost/novius-os.5.0.1-elche/novius-os/?_preview
the XSS is output to its HTML entities. 

e.g. 
<title>&lt;script&gt;alert('HELL')&lt;/script&gt;</title>

But within the same webpage for <h1> tag you can see it is not.

e.g.
<div id="block-grid" class=" customisable col-md-12 col-sm-12 col-xs-12 main_wysiwyg"><h1 id="pagename"><script>alert('HELL')</script></h1>


Local File Inclusion:
---------------------

http://localhost/novius-os.5.0.1-elche/novius-os/admin/?tab=../../../../
