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

修复方案:

你猜啊~~~~
