Tools for auditing WAFS

Project description

# LightBulb
LightBulb is an open source python framework for auditing web applications firewalls.

## Synopsis

The framework consists of two main algorithms:

* **GOFA**: An active learning algorithm that infers symbolic representations of automata in the standard membership/equivalence query model.

Active learning algorithms permits the analysis of filter and sanitizer programs remotely, i.e. given only the ability to query the targeted program and observe the output.

* **SFADiff**: A black-box differential testing algorithm based on Symbolic Finite Automata (SFA) learning

Finding differences between programs with similar functionality is an important security problem as such differences can be used for fingerprinting or creating evasion attacks against security software like Web Application Firewalls (WAFs) which are designed to detect malicious inputs to web applications.

## Motivation

Web Applications Firewalls (WAFs) are fundamental building blocks of modern application security. For example, the PCI standard for organizations handling credit card transactions dictates that any application facing the internet should be either protected by a WAF or successfully pass a code review process. Nevertheless, despite their popularity and importance, auditing web application firewalls remains a challenging and complex task. Finding attacks that bypass the firewall usually requires expert domain knowledge for a specific vulnerability class. Thus, penetration testers not armed with this knowledge are left with publicly available lists of attack strings, like the XSS Cheat Sheet, which are usually insufficient for thoroughly evaluating the security of a WAF product.

## Installation

### Prepare your system

First you have to verify that your system supports python dev, pip and build utilities:

For apt (ubuntu, debian...):
```bash
sudo apt-get install python-pip
sudo apt-get install python-dev
sudo apt-get install build-essential
```

For yum (centos, redhat, fedora...):
```bash
sudo yum install python-pip
sudo yum install python-devel
sudo yum groupinstall 'Development Tools'
```

### Install Lightbulb

In order to use the application without complete package installation:

```bash
git clone https://github.com/lightbulb-framework/lightbulb-framework
cd lightbulb-framework
make
lightbulb status
```

In order to perform complete package installation You can also install it from pip repository:

```bash
pip install lightbulb-framework
lightbulb status
```

The "lightbulb status" command will guide you to install MySQLdb and OpenFst support.
