Advisory ID: ZSL-2015-5220
Type: Local/Remote
Impact: System Access
Risk: (4/5)
Release Date: 05.01.2015

Summary

AdaptCMS is a Content Management System trying to be both simple and easy to use, as well as very agile and extendable. Not only so we can easily create Plugins or additions, but so other developers can get involved. Using CakePHP we are able to achieve this with a built-in plugin system and MVC setup, allowing us to focus on the details and end-users to focus on building their website to look and feel great.

Description

AdaptCMS suffers from an authenticated arbitrary command execution vulnerability. The issue is caused due to the improper verification of uploaded files.
