ecshop 2.x/3.x RCE POC 支持自定义代码

虽然ecshop RCE的漏洞过去了很久,今天在给airbug添加插件的时候想到把它添加上吧。也深感自己还是太菜了,POC代码等内容都是大量参考别人的,我只是一个搬运工,将这些代码整合了而已。

测试环境搭建

有了vulhub 搭建环境变得非常简单了,在配合我的 Vulhub-downloader用于则需下载ecshop环境。非常完美。搭建教程在https://github.com/vulhub/vulhub/blob/master/ecshop/xianzhi-2017-02-82239600/README.zh-cn.md

POC代码

# 支持自定义php代码和2.x 3.x POC
