 Why?:

  The variables $start, $year, $month are not filtered

  In file: /modules/blog/tags.php , list.php , index.php ,
main_index.php , viewpost.php

        $start =(!isset($_GET['start'])) ? '0' : $_GET['start'];

  In file: /modules/blog/archive.php

	$start =(!isset($_GET['start'])) ? '0' : $_GET['start'];
	$month =(!isset($_GET['month'])) ?
error_msg($lang['ARCHIVE_NO_MONTH_SPECIFIED']) : $_GET['month'];
	$year =(!isset($_GET['year'])) ?
error_msg($lang['ARCHIVE_NO_YEAR_SPECIFIED']) : $_GET['year'];

  In file: /modules/blog/control/approve_comments.php ,
approve_posts.php , viewcat.php

        $start =(!isset($_GET['start'])) ? '0' : $_GET['start'];
