Demo for detection and mitigation of HTTP/2 Rapid Reset vulnerability (CVE-2023-44487)

介绍

# ⚡ CVE-2023-44487 Demo – HTTP/2 Rapid Reset Attack

This project demonstrates the HTTP/2 "Rapid Reset" vulnerability (CVE-2023-44487) that allows attackers to overwhelm servers using RST_STREAM frames, causing denial-of-service (DoS). It includes:

- ✅ Exploit test using Golang-based tool
- ✅ Vulnerable Apache HTTP/2 setup via Docker
- ✅ Real-time monitoring with Webmin
- ✅ Firewall-based mitigation with IPTables

- [`Detection/webmin_monitoring.md`](Detection/webmin_monitoring.md) – Monitoring with Webmin
- [`Mitigation/iptables.md`](Mitigation/iptables.md) – Firewall rule to stop the attack
- [`Images/`](Images/)

## ⚙️ Setup Instructions

📄 View full setup guide here:  
[`Setup/setup_guide.md`](Setup/setup_guide.md)

It includes:
- Cloning the original exploit repo
- Building the Golang tool
- Running the vulnerable Apache HTTP/2 container
- Installing and accessing Webmin

## 🕵️ Detection (Webmin Monitoring)

📝 **Guide**: Detection/webmin_monitoring.md

### 📸 Screenshots

Images/webmin_cpu.png     ← Webmin CPU monitor  
Images/apache_log.png     ← Apache access logs  

These visuals confirm that the exploit successfully triggers load and logs corresponding request activity.

## 🛡️ Mitigation (IPTables Firewall Rules)

📄 See: [`Mitigation/iptables.md`](Mitigation/iptables.md)

Highlights:
- Uses `hashlimit` to rate-limit connections per IP
- Drops excess HTTP/2 requests
- Protects the server from resource exhaustion

## Credits

This demo is based on [PatrickTulskie's `reset-rabbit`](https://github.com/PatrickTulskie/reset-rabbit), extended with:

- 🛠️ Step-by-step setup & detection documentation  
- 📊 Visual proof of DoS using Webmin  
- 🔐 Custom IPTables rules to mitigate the attack  

Created for educational use under controlled lab conditions.
