BurpCSJ extension release

As part of my research and talk titled "Augmented Reality in your web proxy" presented during the HackPra AllStars program / OWASP AppSec EU 2013  security conference in Hamburg, I decided to release a new Burp Pro extension which integrates Crawljax, Selenium and JUnit.

I decided to take this approach to increase application spidering coverage (especially for Ajax web apps), speed up complex test-cases and take advantage of the Burp Extender API.

Downloads
  • BurpCSJ extension JAR - download (all dependencies included)
  • BurpCSJ source code - github
  • "Augmented Reality in your web proxy" - presentation (slideshare)
Getting started
  1. Download BurpCSJ;
  2. Load BurpCSJ extension jar via the Extender tab;
  3. Choose the URL item from any Burp tab (e.g. target, proxy history, repeater); 
  4. Right click on the URL item;
  5. Choose menu item "Send URL to Crawljax";
  6. Crawljax will automatically start crawling the URL that you choose.

  2. Attempting to load extension within burp suite on OSX is generating an error. (java.lang.UnsupportedClassVersionError: burp/BurpExtender : Unsupported major.minor version 51.0)
    From what i can tell it is forcing a specific JDK (Java 7?). This will not load with a standard Java installation on OSX and requires updating to a somewhat unsupported Java 7. Can anything be done for compatibility for OSX users?

    1. Hey, thanks for the feedback. I have not tested BurpCSJ on OSX so not sure what exactly could be the issue. Feel free to create a ticket on github: https://github.com/malerisch/burp-csj/issues with full stack trace so I can try to understand why it fails. Thanks.

Pwning a thin client in less than two minutes

Have you ever encountered a zero client or a thin client? It looks something like this... If yes, keep reading below, if not, then if you encounter one, you know what you can do if you read below... The model above is a T520, produced by HP - this model and other similar models are typically employed to support a medium/large VDI (Virtual Desktop Infrastructure) enterprise. These clients run a Linux-based HP ThinPro OS by default and I had a chance to play with image version T6X44017 in particular, which is fun to play with it, since you can get a root shell in a very short time without knowing any password... Normally, HP ThinPro OS interface is configured in a kiosk mode, as the concept of a thin/zero client is based on using a thick client to connect to another resource. For this purpose, a standard user does not need to authenticate to the thin client per se and would just need to perform a connection - e.g. VMware Horizon View. The user will eventually authenticat

Microsoft .NET MVC ReDoS (Denial of Service) Vulnerability - CVE-2015-2526 (MS15-101)

Microsoft released a security bulletin ( MS15-101 ) describing a .NET MVC Denial of Service vulnerability ( CVE-2015-2526 ) that I reported back in April. This blog post analyses the vulnerability in details, starting from the theory and then providing a PoC exploit against a MVC web application developed with Visual Studio 2013. For those of you who want to see the bug, you can directly skip to the last part of this post or watch the video directly... ;-) A bit of theory The .NET framework (4.5 tested version) uses backtracking regular expression matcher when performing a match against an expression. Backtracking is based on the NFA (non-deterministic finite automata) algorithm engine which is designed to validate all input states. By providing an “evil” regex expression – an expression for which the engine can be forced to calculate an exponential number of states - it is possible to force the engine to calculate an exponential number of states, leading to a condition defined su

Trend Micro Threat Discovery Appliance - Session Generation Authentication Bypass (CVE-2016-8584)

In the last few months, I have been testing several Trend Micro products with Steven Seeley ( @steventseeley ). Together, we have found more than 200+ RCE (Remote Code Execution) vulnerabilities and for the first time we presented the outcome of our research at Hack In The Box 2017 Amsterdam  in April. The presentation is available as a PDF or as a Slideshare . Since it was not possible to cover all discovered vulnerabilities with a single presentation, this blog post will cover and analyze a further vulnerability that did not make it to the slides, and which affects the Trend Micro Threat Discovery Appliance (TDA) product. CVE-2016-8584 - TDA Session Generation Authentication Bypass This was an interesting vulnerability, discovered after observing that two consecutive login attempts against the web interface returned the same session_id token. Following this observation, our inference was that time factor played a role. After further analysis and reversing of the TDA libra
