# Apache Airflow Celery 消息中间件命令执行CVE-2020-11981
Apache Airflow是一款开源的分布式任务调度框架。在其1.10.10版本及以前如果攻击者控制了Celery的消息中间件如Redis/RabbitMQ将可以通过控制消息在Worker进程中执行任意命令。
由于启动的组件比较多可能会有点卡运行此环境可能需要准备2G以上的内存。

- <https://github.com/apache/airflow/pull/9178>
## 漏洞环境
依次执行如下命令启动airflow 1.10.10
```bash
#初始化数据库
docker compose run airflow-init
#启动服务
docker compose up -d
```
## 漏洞利用
利用这个漏洞需要控制消息中间件Vulhub环境中Redis存在未授权访问。通过未授权访问攻击者可以下发自带的任务`airflow.executors.celery_executor.execute_command`来执行任意命令,参数为命令执行中所需要的数组。
我们可以使用[exploit_airflow_celery.py](exploit_airflow_celery.py)这个小脚本来执行命令`touch /tmp/airflow_celery_success`
```bash
pip install redis
python exploit_airflow_celery.py [your-ip]
```
查看结果:
```bash
docker compose logs airflow-worker
```
可以看到如下任务消息:

```bash
docker compose exec airflow-worker ls -l /tmp
```
可以看到成功创建了文件`airflow_celery_success`
