# CMSLogik 1.2.1 (upload_file_ajax()) Shell Upload Exploit
#
#
# Vendor: ThemeLogik
# Product web page: http://www.themelogik.com/cmslogik
# Affected version: 1.2.1 and 1.2.0
#
# Summary: CMSLogik is built on a solid & lightweight framework
# called CodeIgniter, and design powered by Bootstrap. This
# combination allows for greater security, extensive flexibility,
# and ease of use. You can use CMSLogik for almost any niche that
# your project might fall into.
#
# Desc: The vulnerability is caused due to the improper verification
# of uploaded files in '/application/controllers/support.php' script
# thru the 'upload_file_ajax()' function. This can be exploited to
# execute arbitrary PHP code by uploading a malicious PHP script file
# with multiple extensions in the '/support_files' directory. Normal
# user [level 113] authentication required.
#

# 146:    $sizeLimit = 10 * 1024;

combination allows for greater security, extensive flexibility,
and ease of use. You can use CMSLogik for almost any niche that
your project might fall into.

Desc: CMSLogik suffers from multiple stored XSS vulnerabilities
when parsing user input to several parameters via POST method.
Attackers can exploit these weaknesses to execute arbitrary HTML
and script code in a user's browser session.

Tested on: Apache/2.2.22
           PHP/5.3.15
