前言
对目前的Apache Struts RCE (CVE-2024-53677)的poc进行总结，由于只能单个ip验证，所以自己更改一下代码，实现：多线程读取url验证并保存，更改为中文解释

自动爬取url地址，检测sql注入漏洞，sqlmc安装+使用
python实现
参考大佬的poc：https://github.com/TAM-K592/CVE-2024-53677-S2-067/
Apache Struts 的以下版本受到影响：2.0.0 至 2.5.33，6.0.0 至 6.3.0.2
根据poc的最近几天的历史，目前网上的最终版本是base64混淆，是昨天中文出来的（2024.12.18中午）
https://github.com/TAM-K592/CVE-2024-53677-S2-067/
我在大佬的基础上进行了一些修改
- 变成了多线程
- 解释变成了中文
usage: CVE-2024-53677-S2-067-thread.py [-h] (-u URL | -f FILE) --upload_endpoint UPLOAD_ENDPOINT [--paths PATHS [PATHS ...]]
[--filenames FILENAMES [FILENAMES ...]] [--payload PAYLOAD] [-s THREADS] [-o OUTPUT]
S2-067 Exploit - 多线程文件上传支持并从文件中读取URL
options:
-h, --help show this help message and exit
-u URL, --url URL 目标基础URL（例如：http://example.com）
-f FILE, --file FILE 包含目标基础URL的文件路径，每行一个URL
--upload_endpoint UPLOAD_ENDPOINT
上传端点路径（例如：/uploads.action）
--paths PATHS [PATHS ...]
路径遍历测试路径
--filenames FILENAMES [FILENAMES ...]
自定义载荷文件名
--payload PAYLOAD 自定义JSP载荷内容
-s THREADS, --threads THREADS
使用的线程数量（默认: 5）
-o OUTPUT, --output OUTPUT
输出成功URL的文件路径（默认：success.txt）
