# Apache Druid 远程代码执行漏洞 QVD-2023-9629
|
||
|
||
## 漏洞描述
|
||
|
||
该漏洞源于 Apache Kafka Connect JNDI 注入漏洞（CVE-2023-25194），Apache Druid 由于支持从 Kafka 加载数据，刚好满足其利用条件，攻击者可通过修改Kafka 连接配置属性进行 JNDI 注入攻击，进而在服务端执行任意恶意代码。
|
||
|
||
## 漏洞影响
|
||
|
||
```
|
||
Apache Druid <= 25.0.0
|
||
```
|
||
|
||
## 网络测绘

|
||
|
||
## 漏洞复现
|
||
|
||
访问漏洞环境，点击 Load data -> Streaming，进入页面后点击 Apache Kafka -> Connect data：
|
||
|
||
|
||
|
||
在 Bootstrap servers 和 Topic 处填入任意字符，点击 Apply，抓包。

|
||
|
||
修改请求包，user.provider.url 处填写你的 ldap 服务 url。
|
||
|
||
利用 DNSLog 验证漏洞是否存在。
|
||
|
||
## 修复建议
|
||
|
||
- 避免 Apache Druid 开放至公网。
|
||
- 开启身份认证机制,可参考官方文档：https://druid.apache.org/docs/latest/development/extensions-core/druid-basic-security.html
