Vendor: Cotonti Team
Product web page: http://www.cotonti.com
Affected version: 0.9.4 (Siena)

Summary: Cotonti is a powerful open-source web development
framework and content manager with a focus on security,
speed and flexibility.

Desc: Input passed via the parameters 'redirect.php' in
'message.php' and 'w' and 'd' in 'index.php' script 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 or execute
arbitrary HTML and script code in a user's browser session
in context of an affected site. Path disclosure resides in
the 'sq' parameter in '/plugins/search/search.php' script.

Tested on: Microsoft Windows 7 Ultimate SP1 (EN)

           Apache 2.2.14 (Win32)
