rustfuzz

rustfuzz is a high-performance, advanced web fuzzer written in Rust. It’s designed for security professionals and developers to discover hidden files, directories, and vulnerabilities on web servers. Inspired by tools like ffuf, rustfuzz emphasizes speed, flexibility, and modern security research workflows.

🚀 Features

• 🌐 URL and Directory Fuzzing: Quickly identify hidden endpoints, files, and directories.
• ⚡ High Performance: Async/multithreaded engine for maximum speed.
• 🧰 Flexible & Customizable:
  • Specify target URLs (-u, --url)
  • Custom wordlists (-w, --wordlist)
  • Status code matching (-m, --matcher)
  • Custom headers, cookies, and authentication tokens

  • Config file support (--config) for reusable setups
  • Proxy support (HTTP/SOCKS5/Burp Suite)
  • Export results (--export) in JSON or CSV
  • Payload injection (--payloads)
  • Mutation-based fuzzing (--mutate)
  • Smart crawling (--crawl) to discover more endpoints
  • OpenAPI/Swagger parsing (--openapi)
  • Results analysis (--analyze)
• 🔒 Modern Security Workflows:
  • Designed for both bug bounty hunters and blue teams
  • Diagnostic output and robust error handling

📦 Installation

1. Clone the repository:

   git clone https://github.com/martian58/rustfuzz.git
   cd rustfuzz

2. Build the project using Cargo:

   cargo build --release

3. The binary will be available at:

   ./target/release/rustfuzz

📖 Usage

Run rustfuzz with your desired options:

./rustfuzz -u <URL> -w <wordlist> -t <threads>

Example (CLI only):

./rustfuzz -u https://example.com/FUZZ -w /path/to/wordlist.txt -t 20

Using a Configuration File

You can store your options in a TOML config file and load them with the --config flag:

./rustfuzz --config rustfuzz.toml

Example rustfuzz.toml:

url = "https://example.com"
wordlist = "wordlists/common.txt"
threads = 20
timeout = 10
matcher = "200,301,302"
proxy = "http://127.0.0.1:8080"
export = "results/output.json"
# Add other options as needed

• Any command-line argument will override the value in the config file.
• The config file supports all options available via CLI.

More Examples

With a proxy (e.g., Burp Suite):

./rustfuzz --config config.toml --proxy http://127.0.0.1:8080

Exporting results:

./rustfuzz -u https://example.com -w words.txt --export results.json

Advanced fuzzing with payloads:

./rustfuzz -u https://example.com --payloads payloads/xss.txt

Smart crawling:

./rustfuzz -u https://example.com --crawl

Analyze exported results:

./rustfuzz --analyze results.json

For the full list of options and help:

./rustfuzz --help
