*Product Introduction:*  
"Daily Edition WordPress Theme developed by wootheme team and Daily Edition  
is a clean, spacious newspaper/magazine theme designed by Liam McKay. With  
loads of home page modules to enable/disable and a unique java script-based  
featured scroller and video player the theme oozes sophistication"  
  
"The Daily Edition theme offers users many options, controlled from the  
widgets area and the theme options page – it makes both the themes  
appearance and functions flexible. From The Daily Edition 3 option pages  
you can for example add your Twitter and Google analytics code, some custom  
CSS and footer content – and in the widgets area you find a practical ads  
management."  
  
"Unique Features  
These are some of the more unique features that you will find within the  
theme:  
A neat javascript home page featured slider, with thumbnail previews of  
previous/next slides on hover over the dots.  
A “talking points” home page that can display posts according to tags,  
in order of most commented to least commented. A great way to highlight  
posts gathering dust in the archives.  
A customizable home page layout with options to specify how many full  
width blog posts and how many “box” posts you would like to display.  
A javascript home page video player with thumbnail hover effect.  
16 delicious colour schemes to choose from!"  
  
  
  
  
  
  
  
*(2) Vulnerability Details:*  
WordPress Daily Edition Theme web application has a security bug problem.  
It can be exploited by "Unrestricted Upload of File" (Arbitrary File  
Uploading) attacks. With a specially crafted request, a remote attacker can  
include arbitrary files from the targeted host or from a remote or local  
host . This may allow disclosing file contents or executing files like PHP  
scripts. Such attacks are limited due to the script only calling files  
already on the target host.  
  
  
*(2.1)* The code flaw occurs at "thumb.php?" page with "src" parameters.
