#
# 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
#
# Zero Science Lab - http://www.zeroscience.mk
# Macedonian Information Security Research And Development Laboratory
#
#
# Advisory ID: ZSL-2014-5196
# Advisory URL: http://zeroscience.mk/en/vulnerabilities/ZSL-2014-5196.php
