Sort of like Slowloris, but for HTTP2. A proof of concept for CVE-2023-44487

This package contains a client that sends HTTP2 stream resets (RST_STREAM) to a local server. It does this by misusing a Go HTTP client error handler that sends a reset if the request Body is longer than the request Content-Length.

To run:

go build && ./http2-rst-stream

It intentionally does not allow targeting of remote web servers out of the box. I'm not trying to help people break stuff.
