GNUCITIZEN

I’ve been meaning to talk about CONFidence and EUSecWest for quite a while, but May was such an intense month for me, that’s hardly left me with any time for other things. I eventually got caught up with other matters, which resulted in me publishing this post about 2 months late.

I’ve been researching, pentesting, and preparing two different presentations which I gave at CONFidence in Krakow, and EUSecWest in London. pdp has also been busy presenting at AusCERT2009. [...]

I couldn’t find any public PoC/exploit for this phpMyAdmin vulnerability, despite it being a serious bug affecting a popular open-source project. I think this vulnerability is a nice reminder that it’s still possible to perform remote command execution these days without relying on SQL injection (i.e.: xp_cmdshell) or a memory corruption bug (i.e.: heap overflow). [...]

Mounting the filesystem on your workstation

There are many ways to mount the camera’s filesystem using the firmware binary. In this post, we’ll explain one way to mount firmware version v1.00R24 which is the latest available for the WVC54GCA model. [...]

This is going to be one of these quick posts which just makes you think what the information security landscape will be like in 5 years. Before I move on with my commentary, here is a video which is essential for you to watch.

Got the idea? No? Let me explain. What you see in the video above is an application for the iPhone which gives you detailed characteristics of properties (houses) in USA. [...]

Oh yes, the digital battlefield is taking unusual shapes. The latest manifestation of cyber warfare is a conflict between the Adblock Plus and the NoScript extensions. The story goes that NoScript used some JavaScript tactics and, of course, some obfuscations in order to cripple the Adblock Plus functionalities. This attack was a response to Adblock Plus blocking NoScript ads which you see when you upgrade the extension, which as you know happens quite regularly, don’t know why. [...]

When I was playing/introducing the partial disclosure practice an year and something ago, I did get contacted by numerous dodgy characters willing to buy yet undisclosed vulnerabilities for substantial amount of money. Of course, requests of that nature were kindly ignored. I couldn’t believe that someone was willing to give me so much money for something I virtually spent 2-3 hours maximum to produce. [...]

Jeriko moved in its own source code repository which you will be able to find here. There is also a discussion group here, if you feel like using it.

The version inside the new code repository is very different from the version you’ve seen before. The main difference is that while the old version is basically a collection of scripts, the new version implements its own shell (wrapper around bash) which does the heavily lifting and also introduces some funky programming mechanisms. [...]

There are two types of vulnerabilities I will be releasing today: disclosure of credentials in client-side source code and multiple XSS. [...]

Unlike the previous two vulnerabilities I released, the vulnerabilities I’m releasing in this post are perhaps not so useful to break into the device as you need access to the admin account to exploit them. [...]

Privilege escalation via arbitrary file retrieval

The second vulnerability I’ll be releasing is an arbitrary(ish) file retrieval vulnerability. It’s not fully arbitrary because you can only retrieve the contents of files located within the same directory where the vulnerable CGI program is located. [...]
