Filebuster

An extremely fast and flexible web fuzzer

What is it?

Filebuster is an HTTP fuzzer / content discovery script with loads of features and built to be easy to use and fast! It uses one of the fastest HTTP classes in the world (of PERL) – Furl::HTTP. Also the thread modelling is optimized to run as fast as possible.

Features

It packs a ton of features like:

  • Regex patterns on wordlists
  • Supports HTTP/HTTPS/SOCKS proxy
  • Allows for multiple wordlists using wildcards
  • Additional file extensions
  • Adjustable timeouts and retries
  • Adjustable delays / throttling
  • Hide results based on HTTP code, length or words in headers or body
  • Support for custom cookies
  • Support for custom headers
  • Supports multiple versions of the TLS protocol
  • Automatic TTY detection
  • Recursive scans
  • Integrated wordlists with custom payloads
  • Automatic smart encoding
  • Automatic filtering of results

Filebuster is updated often. New features will be added regularly.

 

Why is it so fast?

Filebuster was built based on one of the fastest HTTP classes in the world (of PERL) – Furl::HTTP. Also, thread modelling is a bit optimized to run as fast as possible.

Requisites

Perl version 5.10 or higher is required

Filebuster resources a lot of features to third-party libraries. However, they can be easily installed with the following command:

# cpan -T install YAML Furl Switch Benchmark Cache::LRU Net::DNS::Lite List::MoreUtils IO::Socket::SSL URI::Escape HTML::Entities IO::Socket::Socks::Wrapper

Installation

git clone https://github.com/henshin/filebuster.git

Filebuster is a Perl script so no installation is necessary. However, the best way of using filebuster is by creating a soft link on a directory that is included in the path. For example:

# ln -s /path/to/filebuster.pl /usr/local/bin/filebuster

Then you will be able to use it system wide

On the most basic form, Filebuster can be run just using the following syntax:

# filebuster -u http://yoursite.com/

If you want to fuzz the final part of the URL, then you don’t need to use the tag {fuzz} to indicate where to inject.

The wordlist parameter (-w) is not mandatory as from version 0.9.1. If not specified, Filebuster will attempt to find and load the “Normal” wordlist automatically.

A more complex example:

# filebuster -u http://yoursite.com/{fuzz}.jsp -w /path/to/wordlist.txt -t 3 -x http://127.0.0.1:8080 --hs "Error"

 

This would allow you to fuzz a website with 3 threads to find JSP pages, using a local proxy and hiding all responses with “Error” in the body.

For the complete syntax help with examples, just run filebuster.pl –help.

Wordlists

I’ve created some wordlists based on different sources around the web together with my own custom payloads that I’ve come across during my pentests and research. You can find them in the wordlists directory. If you need more wordlists, you should check out the great SecLists repository.
