[中文版本(Chinese version)](README.zh-cn.md)

YApi is a API testing tools for enterprise. YApi which in the version prior to v1.12.0, are vulnerable to a NoSQL injection, as well as a remote code execution vulnerability. The remote attacker could steal project's token through NoSQL injection without authentication and use this token to execute the Mock script and get shell.

## Vulnerable Environment

Execute following command to start a YApi server v1.10.2:

```
docker compose up -d
```

After the server is started, you can browse the website at `http://your-ip:3000/`.

## Exploit

The target in Vulhub is a ready-to-use server that contains some example data in MongoDB. So just use [this POC](poc.py) to reproduce the issue:

```
python poc.py --debug one4all -u http://127.0.0.1:3000/
```
