druid 远程命令执行 (CVE-2021-25646) druid 远程命令执行 (CVE-2021-25646) 漏洞介绍:

Apache Druid 是用Java编写的面向列的开源分布式数据存储,旨在快速获取大量事件数据,并在数据之上提供低延迟查询。 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发送恶意请求,利用Apache Druid漏洞可以执行任意代码

影响版本:

Apache Druid <= 0.20.1

环境搭建:

采用在线环境 地址

漏洞复现:

访问首页,点击Load data进行上传

点击Local disk 

 填写路径以及上传的gz文件

 

base directory: quickstart/tutorial/

File filter: wikiticker-2015-09-12-sampled.json.gz 

点击preview进行上传 

 

上传成功后,点击下一步,直到抓取到filter页面 

 替换数据包中POST的Data数据,改成我们的POC,cacheKey值换成自己的,dnslog申请一个地址
