couponPHP CMS 1.0 Multiple Stored XSS and SQL Injection Vulnerabilities


Vendor: couponPHP
Product web page: http://www.couponphp.com
Affected version: 1.0

Summary: couponPHP is a revolutionary content management system
for running Coupon and Deal websites. It is feature rich, powerful,
beautifully designed and fully automatic.

Desc: couponPHP is vulnerable to multiple Stored XSS and SQL Injection issues.
Input passed via the parameters 'iDisplayLength' and 'iDisplayStart' in
'comments_paginate.php' and 'stores_paginate.php' scripts are not properly
sanitised before being returned to the user or used in SQL queries. This can
be exploited to manipulate SQL queries by injecting arbitrary SQL code.

The parameter 'sEcho' in 'comments_paginate.php' and 'stores_paginate.php' and the
parameters 'affiliate_url', 'description', 'domain', 'seo[description]', 'seo[heading]',
'seo[title]', 'seo[keywords]', 'setting[logo]', 'setting[perpage]' and 'setting[sitename]'
in '/admin/index.php' script are vulnerable to stored XSS issues where the attacker
can execute arbitrary HTML and script code in a user's browser session in context
of an affected site.


Tested on: Apache/2.2.14(Ubuntu)
           PHP/5.3.2-1ubuntu4.14
