an open-source PHP-based internet bulletin board software.

The remote version of this software is vulnerable to a remote file
include flaw due to a lack of sanitization of user-supplied data.

Successful exploitation of this issue may allow an attacker to execute 
malicious script code on a vulnerable server.
