http://secunia.com/advisories/16832/

CRITICAL:
Highly critical

IMPACT:
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 compromise a vulnerable system.

Input passed to the "Client-IP" HTTP header when adding a comment
isn't properly sanitised before being stored in the file
"data/flood.db.php" inside the web root. This can be exploited to
inject and execute arbitrary PHP code.

Successful exploitation requires that support for ".htaccess" files
is disabled.

The vulnerability has been confirmed in version 1.4.0. Other versions
may also be affected.

SOLUTION:
Enable support for ".htaccess" files.

Edit the source code to ensure that input is properly sanitised.
