好好学习,天天向上
elasticsearch 1.5.1及以前,无需任何配置即可触发该漏洞。之后的新版,配置文件elasticsearch.yml中必须存在path.repo,该配置值为一个目录,且该目录必须可写,等于限制了备份仓库的根位置。不配置该值,默认不启动这个功能。
1.6.1以下
这里使用v1.6.0版本
使用vulhub
cd /app/vulhub-master/elasticsearch/CVE-2015-5531
使用docker启动
docker-compose up -d
环境启动后,访问http://your-ip:9200
http://192.168.239.129:9200
直接上POC,cve-2015-5331.py,内容如下(不需要修改)

执行命令(IP自己改)
python cve-2015-5331.py 192.168.239.129 /etc/passwd
关闭镜像(每次用完后关闭)
docker-compose down
拉镜像(进入到vulhub某个具体目录后)
docker-compose builddocker-compose up -d
镜像查询(查到的第一列就是ID值)
docker ps -a
进入指定镜像里面(根据上一条查出的ID进入)
docker exec -it ID /bin/bash
关闭镜像(每次用完后关闭)
docker-compose down
