简要描述：

在Ecshop中缺乏对参数的有效过滤，导致一个SQL注射漏洞，成功利用该漏洞的攻击者可以获得数据库及站点的完全权限。

详细说明：

在include_libcommon.php中存在如下函数

function get_package_info($id)
{
    global $ecs, $db,$_CFG;
    $now = gmtime();
    $sql = "SELECT act_id AS id,  act_name AS package_name, goods_id , goods_name, start_time, end_time, act_desc, ext_info".
           " FROM " . $GLOBALS['ecs']->table('goods_activity') .
           " WHERE act_id='$id' AND act_type = " . GAT_PACKAGE;
    $package = $db->GetRow($sql);
    /* 将时间转成可阅读格式 */
    if ($package['start_time'] <= $now && $package['end_time'] >= $now)
    {
        $package['is_on_sale'] = "1";
    }
    else
    {
        $package['is_on_sale'] = "0";
    }
    $package['start_time'] = local_date('Y-m-d H:i', $package['start_time']);
    $package['end_time']   = local_date('Y-m-d H:i', $package['end_time']);
    $row = unserialize($package['ext_info']);
    unset($package['ext_info']);
    if ($row)
    {
        foreach ($row as $key=>$val)
        {
            $package[$key] = $val;
        }
    }
    $sql = "SELECT pg.package_id, pg.goods_id, pg.goods_number, pg.admin_id, ".
           " g.goods_sn, g.goods_name, g.market_price, g.goods_thumb, g.is_real, ".
           " IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS rank_price " .
           " FROM " . $GLOBALS['ecs']->table('package_goods') . " AS pg ".
           "   LEFT JOIN ". $GLOBALS['ecs']->table('goods') . " AS g ".
           "   ON g.goods_id = pg.goods_id ".
           " LEFT JOIN " . $GLOBALS['ecs']->table('member_price') . " AS mp ".
                "ON mp.goods_id = g.goods_id AND mp.user_rank = '$_SESSION[user_rank]' ".
           " WHERE pg.package_id = " . $id. " ".
           " ORDER BY pg.package_id, pg.goods_id";
    $goods_res = $GLOBALS['db']->getAll($sql);
    $market_price        = 0;

其中$id没有经过严格过滤就直接进入了SQL查询，导致一个SQL注射漏洞。

漏洞证明：

在系统的lib_order.php中存在一个该函数的调用

function add_package_to_cart($package_id, $num = 1)
{
    $GLOBALS['err']->clean();
    /* 取得礼包信息 */
    $package = get_package_info($package_id);
    if (empty($package))
    {
        $GLOBALS['err']->add($GLOBALS['_LANG']['goods_not_exists'], ERR_NOT_EXISTS);
        return false;
    }

在flow.php中存在可控的输入源

$package = $json->decode($_POST['package_info']);
    /* 如果是一步购物，先清空购物车 */
    if ($_CFG['one_step_buy'] == '1')
    {
        clear_cart();
    }
    /* 商品数量是否合法 */
    if (!is_numeric($package->number) || intval($package->number) <= 0)
    {
        $result['error']   = 1;
        $result['message'] = $_LANG['invalid_number'];
    }
    else
    {
        /* 添加到购物车 */
        if (add_package_to_cart($package->package_id, $package->number))
        {
            if ($_CFG['cart_confirm'] > 2)

$package->package_id来源于输入
