PortSwigger moves into “Challengers” Quadrant in 2014 Gartner Magic Quadrant for Application Security Testing for its web security solution

In July 2014 Gartner released its annual Magic Quadrant for Application Security Testing.

The report published by analysts Joseph Feiman and Neil MacDonald evaluates organizations based on ‘completeness of vision’ and ‘ability to execute’. Gartner have positioned PortSwigger Web Security in the ‘challengers’ quadrant, and according to the report:
“Challengers in this magic quadrant are vendors that have executed consistently, typically by focusing on a single technology. In addition, they have demonstrated substantial competitive capabilities against the leaders in this particular focus area and also have demonstrated momentum in their customer base in overall size and growth.”
Dafydd Stuttard, founder of PortSwigger Web Security, said: “We are delighted that Gartner have recognized us as a challenger in this market. Burp Suite is a powerful web scanning tool, and is extremely competitively priced. It is one of the most widely adopted tools in the market, with users in over 90 countries and a majority of the Fortune 100 companies. Burp Suite provides its users with exceptional capabilities and value for money.”

In this new report, Feiman and MacDonald state that “Global-scale scandals around critical applications’ breaches have highlighted the need for effective detection of exploitable application security vulnerabilities. Application security testing is the solution for web, cloud and mobile applications”.

In the past year, PortSwigger Web Security has accelerated its investment in Burp Suite, and expanded its core team. We have a very ambitious roadmap for the product, driven by the continual changes in web security and our customers’ requirements. We have some major product enhancements planned through 2014 and 2015, which will continue to raise the bar in web security testing.

Burp gets new JavaScript analysis capabilities

The latest release of Burp includes a new engine for static analysis of JavaScript code. This enables Burp Scanner to report a range of new vulnerabilities, including:
  • DOM-based XSS
  • JavaScript injection
  • Client-side SQL injection
  • WebSocket hijacking
  • Local file path manipulation
  • DOM-based open redirection
  • Cookie manipulation
  • Ajax request header manipulation
  • DOM-based denial of service
  • Web message manipulation
  • HTML5 storage manipulation

In the initial release, the new functionality is officially experimental, and will be enhanced in future releases based on user feedback. The key areas for further enhancement are as follows:
  • Burp supports most core JavaScript language features, including local and global variables, function calls and return values, assignments, arrays, and relevant platform APIs. Two important language features are not supported: object dereferences and function pointer variables. Some vulnerabilities that are dependent on these language features are not currently reported.
  • Static code analysis is resource intensive. We have worked hard on the code analysis engine to minimize memory and CPU consumption, and its performance has been extensively tested against real-world code. However, there is more work yet to do in this area, and in the initial release it may be necessary to (a) increase the memory that is assigned to the Java process; (b) restrict static code analysis to key targets of interest; (c) configure a suitable maximum analysis time for complex items. See the static code analysis options for more details.
  • In a future release, we may provide a UI similar to the active scan queue, containing a view of pending and current code analysis tasks, and enabling the user to pause, resume or cancel individual tasks.
  • Some further refinement may be necessary of Burp's rules for identifying tainted sources and dangerous sinks, and mapping these to vulnerability types.
Despite the above opportunities for enhancement, the current functionality is sufficiently powerful that it would be wrong for us to sit on it any longer, and it's time for users to try it out in real-world situations. Feedback is actively welcomed about the new capabilities, to help drive the above and other improvements.

How does Burp's code analysis work? We don't simply match suspicious code based on patterns, which is too error-prone and only finds the simplest bugs. We don't execute the code, or fuzz the DOM in an instrumented browser, as this can lead to worse performance problems, many missed vulnerabilities, and poor code coverage due to missed execution branches. We don't employ any external dependencies as these can be brittle and a pain for users to set up.

Rather, Burp contains a home-grown language parser and dataflow analysis engine. We identify places in the code where data is read from potentially tainted sources within the DOM, and trace this data through possible execution paths in the code. If the data can reach a dangerous sink, then a potential vulnerability is reported. This is not, of course, a new approach to static code analysis, but there are many challenges in the details that we believe we have solved in novel and effective ways.

Have fun!

This is a significant upgrade with a wealth of new features added since v1.5, including:
  • Support for WebSockets messages.
  • Support for PKCS#11 client SSL certificates contained in smart cards and physical tokens.
  • A new Extender tool, allowing dynamic loading and unloading of multiple extensions.
  • A new powerful extensibility API, enabling extensions to customize Burp's behavior in much more powerful ways.
  • Support for extensions written in Python and Ruby.
  • A new BApp Store feature, allowing quick and easy installation of extensions written by other Burp users.
  • An option to resolve DNS queries over a configured SOCKS proxy, allowing access to TOR hidden services.
  • Generation of CSRF PoC attacks using a new cross-domain XHR technique.
  • New options for SSL configuration, to help work around common problems.
  • Optional unpacking of compressed request bodies in the Proxy.
  • Support for .NET DeflateStream compression.
  • New and improved types of Intruder payloads.

Introducing the BApp Store

Today's release of Burp includes a brand new feature: the BApp Store. This contains Burp extensions that have been written by users of Burp Suite, to extend its capabilities.

You can install BApps with one click from within Burp:


You can also download BApps from the BApp Store web site, for manual installation on Burp machines without an Internet connection:


All BApps are free! We may support paid-for BApps in future, but we have no current plans to do so.

We really hope that the new feature will help users find and use good quality Burp extensions that other users have shared. You can rate BApps that you have used, and see the aggregated ratings submitted by other users.

We also hope that the BApp Store will encourage more extension authors to create and share great Burp extensions. We'll be adding more BApps to the store in the near future. If you have written or are aware of a great Burp extension that you'd like included in the BApp Store, please submit your BApp to us.

Burp Suite Pro shines in new survey

A new survey has just been published comparing the performance of 63 different web application security scanners. This is what it says overall about Burp Suite Pro:
"Burp is the undisputed winner of the overall versatility category, was the winner in the input vector support category, got one of the highest scores in detecting Backup/Hidden Files, and decent scores in many other categories. It also came out FIRST in the SQL Injection and Reflected XSS categories, and dramatically improved its RFI score."
There is a lot of technical detail in the survey results that we plan to work through, to understand exactly how Burp performed, and can be improved even further.

In the past few months, we've made numerous significant enhancements to Burp Scanner, adding support for nested insertion points, new payload encodings, new categories of vulnerability, and improved coverage of existing scan checks. But we're far from complacent: this year we will continue enhancing the Scanner engine to find even more edge-case vulnerabilities, and also the Spider tool to improve Burp's fully automated crawling capabilities.

As always, new features and enhancements to Burp Suite Pro are made available free to licensed users, and the cost of a Burp license will not be increasing during 2014.
