DESCRIPTION:
Kacper has discovered a vulnerability in TR Newsportal, which can be
exploited by malicious people to compromise a vulnerable system.

Input passed to the "file_newsportal" parameter in
extras/poll/poll.php isn't properly verified, before it is used to
include files. This can be exploited to include arbitrary files from
external and local resources.

Successful exploitation requires that "register_globals" is enabled.

The vulnerability has been confirmed in version 0.36tr1. Other
versions may also be affected.

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

Set "register_globals" to "Off".
