I have been working on an online Burp Suite training for quite some time. It is finally ready.

Advanced sqlmap features – eval

I was always sad when I couldn’t use sqlmap when the injection was not very simple. Of course I always expected that to be my fault, that I didn’t spent enough time to configure sqlmap properly. So the other day when I tested an application and found an sql injection which was a pain in the neck to exploit manually, I rolled up my sleeves and started to look at source code of sqlmap to figure out some parameters which I never knew what they did. This blog post is about the --eval parameter which allows you to manipulate the requests before sending them.

Slides: Security Implication of the Cross-Origin Resource Sharing

As I mentioned in the CORS: Attack scenarios and the CORS: Attacker Model posts, I held the presentation about the security of CORS at the Hacktivity conference in Budapest. The presentation slides can be downloaded from here. If you have any questions to the topic, then let me know.

CORS: Attack scenarios

I was preparing myself for the Hacktivity conference in Budapest, where I talked about the security of the Cross-Origin Resource Sharing (CORS). As part of the preparation I summarised my thoughts in a couple of blog posts. This is one of them.

As a follow up of my previous post, I would like to continue with the short analysis of the threats and attack scenarios which could exploit CORS.

To start off with I will describe the potential attackers who could try to use CORS in their attacks and I will build an attacker model.

Here it is, the file upload CSRF

Recently I wanted to do a Cross Site Request Forgery Proof-of-Concept for a file upload functionality. As you might know it is not necessarily as easy as simple form CSRFs. Continue reading

SoapUI with Burp

In a recent project I tested a web service and we got a nice SoupUI project for it. SoupUI is a great tool but you somehow miss the nice features of Burp, such as the Intruder. But of course the idea comes immediately: why not to chain them? It turns out this is not as trivial as it seems for the first sight.

Please, don’t use user supplied XSLT

I didn’t even want to write about this, because hopefully it is not a wide spread problem but it is such a catastrophic programming mistake which I saw in a production system that I felt the need to talk about it. So to summarize this blog post in one sentence: total client-side exploit using user defined XSLT.

Experiences in pentesting DWR

I was lucky enough to do a penetration test on applications using Direct Web Remoting (DWR), and I would like to share my experiences. It is another interesting technology in the wild jungle of the web frameworks and libraries. It defines itself as follows:
“DWR is a Java library that enables Java on the server and JavaScript in a browser to interact and call each other as simply as possible.”
