Re: Mybb 1.6.8 'announcements.php' Sql Injection Vulnerabilitiy

[Yaniv Shaked <yaniv0a () gmail com>]

Look at the code at announcements.php:

$aid = intval($mybb->input['aid']);

[Boring lines…]

[Boring lines…]

$query = $db->query("
        SELECT u.*, u.username AS userusername, a.*, f.*
        FROM ".TABLE_PREFIX."announcements a
        LEFT JOIN ".TABLE_PREFIX."users u ON (u.uid=a.uid)
        LEFT JOIN ".TABLE_PREFIX."userfields f ON (f.ufid=u.uid)
        WHERE a.startdate<='$time' AND (a.enddate>='$time' OR a.enddate='0') AND a.aid='$aid'
");

$announcementarray = $db->fetch_array($query);

Complete the missing part :)
