[|Description:|]
A security breach has been discoverd in IceBB 1.0-rc6.
This breach is caused by a bad filtering of the X-Forwarded-For variable:
> ./includes/functions.php, line 73
$ip = empty($_SERVER['HTTP_X_FORWARDED_FOR']) ? $_SERVER['REMOTE_ADDR'] : $_SERVER['HTTP_X_FORWARDED_FOR'];
$ip = $this->clean_key($ip);
$input['ICEBB_USER_IP'] = $ip;
> ./icebb.php, line 169
$icebb->client_ip = $input['ICEBB_USER_IP'];
> ./admin/index.php, line 112
$icebb->adsess = $db->fetch_result("SELECT adsess.*,u.id as userid,u.username,u.temp_ban,g.g_view_board FROM icebb_adsess AS adsess LEFT JOIN icebb_users AS u ON u.username=adsess.user LEFT JOIN icebb_groups AS g ON u.user_group=g.gid WHERE adsess.asid='{$icebb->input['s']}' AND adsess.ip='{$icebb->client_ip}' LIMIT 1");
A hacker could exploit this security breach in order to alter a SQL request.

No one. Think about update your forum core when a patch will be available on the official website.
