# CVE-2025-9784 MadeYouReset HTTP/2 Vulnerability Test

## Overview

This repository contains a simple and effective bash script to test for the CVE-2025-9784 vulnerability (known as the "MadeYouReset" HTTP/2 Denial of Service (DoS) attack) in Undertow HTTP/2 server implementations. The vulnerability allows attackers to induce excessive server workload by repeatedly causing server-side stream resets, leading to potential service disruption.

## Features

- Detects if the target server supports HTTP/2 protocol.
- Measures baseline response times.
- Simulates rapid concurrent HTTP/2 stream creation to trigger resets.
- Analyzes server response behaviors under load.
- Provides a straightforward vulnerability assessment report.

## Getting Started

### Prerequisites

- Bash shell (Linux, macOS, WSL)
- `curl` with HTTP/2 support
- Optional: `bc` for floating-point arithmetic (most Linux distros include this by default)

### Usage

1. Clone or download this repository.
2. Make the script executable:
```
chmod +x cve-2025-9784-test.sh
```
4. Run the script against a target URL:
```
./cve-2025-9784-test.sh https://target-website.com
```


### Output

- The script will output test progress and results, highlighting if any signs of potential vulnerability are detected.
- It checks the server's HTTP/2 capability, baseline response times, and simulates attack conditions.
- Final assessment notes if the server might be vulnerable based on response failure and delay patterns.

## Important Notes

- Only test against systems you own or have explicit permission to assess.
- This script does **not** exploit the vulnerability but stresses the server to observe response anomalies.
- The vulnerability affects certain Undertow server implementations primarily found in Red Hat products and other Java-based servers.
