CVE-2023-44487 PoC — Apache HTTP/2 资源管理错误漏洞

Description

A tool to check how well a system can handle Rapid Reset DDoS attacks (CVE-2023-44487).

介绍

# HTTP/2 Rapid Reset Client (C#)

The HTTP/2 Rapid Reset Client, implemented in C#, is designed for testing mitigations and assessing vulnerability to the CVE-2023-44487 (Rapid Reset DDoS attack vector). This client establishes a lone TCP socket, conducts TLS negotiation while disregarding certificates, and engages in the exchange of SETTINGS frames. Subsequently, the client swiftly dispatches HEADERS frames, succeeded by RST_STREAM frames. It actively monitors server frames post-initial setup and outputs them to the console.

## Prerequisites

- [.NET SDK](https://dotnet.microsoft.com/download)

## Installation
