HTTP3 Proxy Tester

This tool automatically tests if a proxy correctly validates malformed HTTP requests. The code is based on a paper called "HTTP/3 will not Save you from Request Smuggling: A Methodology to Detect HTTP/3 Header (mis)Validations"

This repository contains both the tool and some proxies that you can use to test the tool.

How to run the proxies

Each directory contains a proxy setup, except for Aioquic every other proxy is dockerized, so just go on the directory and run

docker-compose up --build -d

For Aioquic you need to clone the repository (https://github.com/aiortc/aioquic.git). Then put the /aioquic/aioquic/proxy.py file (of this repository) inside /examples/ (of the Aioquic repository). Then you can run the following command to start the server

python3 examples/http3_server.py --certificate tests/ssl_cert.pem --private-key tests/ssl_key.pem --port 443 -v proxy:app

How to run the tool

After the proxy is correctly running you can type the following command to run the tests

python3 smuggling.py https://localhost:443

A huge thank you to the users that provide fully configured dockerized instances of proxies
