TITLE:
phpGroupWare Local File Inclusion Vulnerability

SECUNIA ADVISORY ID:
SA21687

VERIFY ADVISORY:
http://secunia.com/advisories/21687/

CRITICAL:
Moderately critical

IMPACT:
Exposure of sensitive information

WHERE:
>From remote

SOFTWARE:
phpGroupWare 0.x
http://secunia.com/product/1814/

DESCRIPTION:
Kacper has discovered a vulnerability in phpGroupWare, which can be
exploited by malicious people to disclose sensitive information.

Input passed to the "phpgw_info[user][preferences][common][country]"
parameter in calendar/inc/class.holidaycalc.inc.php isn't properly
verified, before it is used to include files. This can be exploited
to include arbitrary files from local resources.

Successful exploitation requires that "register_globals" is enabled
and that "magic_quotes_gpc" is disabled.

The vulnerability has been confirmed in version 0.9.16.010 on the
Microsoft Windows platform. Other versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified.

Set "register_globals" to "Off".
