The remote host is vulnerable to a flaw that allows attackers to retrieve sensitive files or data.
The remote host appears to be running Ikonboard, a bulletin board service implemented in Perl. This version is reported to be vulnerable to a file disclosure flaw within the session.php file. Specifically, when the server is configured with PHP 'magic_quotes_gpc' disabled, a remote attacker can use session.php to read any file on the web server that is readable by the web process owner.
Upgrade to version 2.0.10 or higher.
