CAT – Web Application Security Test & Assessment Tool

 Over the 12 years during which Context has been conducting application tests for clients there have been many developments in application security practices. Applications have become more complex, and we have had to expand and enhance testing methods to ensure that we continue to deliver the most thorough assessment possible. In 2007 we identified a need for a new tool designed to test the most complex applications; a tool capable of various different tests as yet unavailable on the market.

These tests included:
  • Complex authorisation models
  • Ability to test complex multi-phase forms e.g. single sign-on (SSO) systems
  • Fuzzing forms protected by cross site request forgery (CRSF) tokens
  • Supporting different encodings used by web services, Ajax and to leverage complex vulnerabilities
  • Ability to perform sensitive timing attacks
  • Heavy Ajax applications
No such tool existed – so we developed one ourselves instead. The result, the Context App Tool (CAT), has become the core application testing tool used at Context.

CAT is designed to facilitate manual web application penetration testing for more complex, demanding application testing tasks. It removes some of the more repetitive elements of the testing process, allowing the tester to focus on individual applications, thus enabling them to conduct a much more thorough test.

Conceptually it is similar to other proxies available both commercially and open source, but CAT provides a richer feature set and greater performance, combined with a more intuitive user interface.

There are a number of differences between CAT and currently available web proxies. They include:
  • CAT uses Internet Explorer’s rendering engine for accurate HTML representation
  • It supports many different types of text conversions including: URL, Base64, Hex, Unicode, HTML/XML, SQL and JavaScript no quotes
  • It offers integrated SQL Injection and XSS Detection
  • Synchronised Proxies for Authentication and Authorisation checking
  • Faster performance due to HTTP connection caching
  • SSL Version and Cipher checker using OpenSSL
  • Greater flexibility for importing/exporting logs and saving projects
  • Tabbed Interface allows for multiple tools at once e.g. multiple repeaters & different logs
  • The ability to repeat and modify a sequence of requests (particularly useful in SSO testing)
  • It’s free!
Do bear in mind that this is a free tool, but it is NOT Open Source. Also take a good look at the EULA before using it (especially Section 6).
