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.
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.
