Subere - OWASP JBroFuzz Project

Overview

JBroFuzz is a stateless network protocol fuzzer that emerged from the needs of penetration testing. The purpose of this application is to provide a single, portable application that offers stable cross-platform network protocol fuzzing capabilities. At the same time, JBroFuzz attempts to keep the User Interface (UI) as intuitive as possible.

Fuzzing

As seen by the emphasis given on the subject of fuzzing in the 2007 Testing Guide (v2), network protocol fuzzing serves as a fundamental cornerstone of application security testing. For this, many different categories and types of fuzzing have been defined.

Objectives

JBroFuzz needs to expand and grow in order to cover network fuzzing in a more complete manner. Its modular implementation allows for the addtion of new functionality by means of independent tabs. The key tabs proposed to be added during the spring of code 2007 are

  • Open Source Tab
  • NTLM Brute Force over HTTP/S Tab
  • Pure HTTP/S Fuzzing using HTTPClient
  • Blind SQL Injection Fuzzing Tab

At the same time, the following existing tabs need to be updated and made more robust (details in next section):

  • TCP Fuzzing tab allowing graph outputs
  • TCP Sniffing tab update thread Agent Queue
  • Update Generators file format
  • Include SOAP and XML fuzzing

This expansion process relates to stabilising code that is presently included in JBroFuzz, thus allowing it to run for extensive periods of time (24h+) as well as adding more functionality in terms of the three new tabs.

Deliverables

Based on the above, the new code elements that will be added are as follows:

  • Open Source Tab: Provide the ability to enumerate e-mails from newsgroups without breaching google automated search rules
  • NTLM Brute Force over HTTP/S Tab: Provide the ability to enumerate NTLM as well as brute over HTTP/S NTLM.
  • Blind SQL Fuzzing Tab Implement a tab that extracts information from a blind SQL injection point identified on web server over HTTP/HTTPS.

For updating existing code elements that require a partial rewrite, the following areas of focus are presented in detail:

  • TCP Fuzzing tab allowing graph outputs: Provide the ability to graph fuzzing results during a particular session run. This will give the ability to integrate and pickup potential fuzzing patterns.
  • TCP Sniffing tab update thread Agent Queue: Update the code of the sniffing panel in order to handle threaded agents in a more
  • Update Generators file format: Update the generators file format to allow for the parsing and creation of recursive generators.
  • Include SOAP and XML fuzzing: Include an up to date list of SOAP and XML fuzzing templates.

Overall, the above two lists of changes should provide sufficient complexity and output for the spring of code 2007, forming a challenging implementation project.

Background

In its short life, the OWASP JBroFuzz Project has attracted the interest of the online security community with a total of appr. 5000 downloads in the last months.

Coming from a strong java background (5+ years) I decided to implement and release JBroFuzz in order to initially simplify penetrations testing processes that relate to web application and network protocol fuzzing.

I see the spring of code 2007 as a unique opportunity to industrialise network protocol fuzzing (and in particular HTTP/S fuzzing) within a single application, residing within OWASP.

Why I should be sponsored for the project

Centralising fuzzing resources into one application that has the ability to handle network protocol fuzzing over HTTP and HTTPS in a simple and intuitive manner forms an area of focus that should not be dismissed in building secure software applications.

Keep the code platform independent adds a huge advantage.

Receving an OWASP grant from the spring of code 2007 will trigger a share in the budget with all active participants depending on their level of involvement. This will be a direct function of the number of tabs and/or user functionality that they have assisted in implementing.
