CuteNews "template" Local File Inclusion Vulnerability

SECUNIA ADVISORY ID:
SA17435

VERIFY ADVISORY:
http://secunia.com/advisories/17435/

CRITICAL:
Highly critical

IMPACT:
Exposure of sensitive information, System access

WHERE:
>From remote

SOFTWARE:
CuteNews 1.x
http://secunia.com/product/1798/

DESCRIPTION:
rgod has discovered a vulnerability in CuteNews, which can be
exploited by malicious people to disclose sensitive information and
compromise a vulnerable system.

Input passed to the "template" parameter in "show_archives.php" and
"show_news.php" isn't properly verified, before it is used to include
files. This can be exploited to include arbitrary files from local
resources.

This can further be exploited to execute arbitrary PHP code by
including the "inc/ipban.mdu" script where PHP code can be injected
via the "add_ip" parameter.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerability has been confirmed in version 1.4.1. Other versions
may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
