#

# ImpressPages CMS v3.6 manage() Function Remote Code Execution Exploit

#

# Vendor: ImpressPages UAB

# Product web page: http://www.impresspages.org

# Affected version: 3.6, 3.5 and 3.1

#

# Summary: ImpressPages CMS is an open source web content management system with

# revolutionary drag & drop interface.

#

# Desc: The vulnerability is caused due to the improper verification of uploaded

# files in '/ip_cms/modules/developer/config_exp_imp/manager.php' script thru the

# 'manage()' function (@line 65) when importing a configuration file. This can be

# exploited to execute arbitrary PHP code by uploading a malicious PHP script file

# that will be stored in '/file/tmp' directory after successful injection.

# Permission Developer[Modules exp/imp] is required (parameter 'i_n_2[361]' = on)

# for successful exploitation.

#

# Tested on: Microsoft Windows 7 Ultimate SP1 (EN)

# GNU/Linux CentOS 6.3 (Final)

# Apache 2.4.2 (Win32) / Apache2

# PHP 5.4.7 / PHP 5.3.21

# MySQL 5.5.25a

#

# Vulnerability discovered by Gjoko 'LiquidWorm' Krstic
