描述：Form-Data是FormData开源的一个用于创建可读的表单数据流的模块。可用于向其他web应用程序提交表单和文件上传。 form-data 2.5.4之前版本、3.0.0至3.0.3版本和4.0.0至4.0.3版本存在安全漏洞，该漏洞源于随机性不足，可能导致HTTP参数污染攻击。
描述
POC of CVE-2025-7783
介绍
# form-data boundary randomness vulnerability (CVE-2025-7783)
Largely based on https://hackerone.com/reports/2913312 by https://hackerone.com/parrot409?type=user
Installing:
- `npm install`
- Make sure you have `python3` installed with the `z3` module (`pip3 install -r requirements.txt`) -- the exploit code shells out to `python3` to predict the next random value
Running:
In parallel, run:
- `npm run start-backend` (the backend server that will receive the manipulated request)
- `npm run start-vulnerable-server` (the frontend server that can be tricked into sending a manipulated request)
- `npm run exploit` (the client code that crafts and sends the exploit)
In the stdout of `npm run backend`, you should see a request with `is_admin: true` (despite the code in `vulnerable-server.js` never intending to add an is_admin parameter to the API call)
