At this years ARES conference, Jonas Plum (Siemens) and me (Andreas Dewald, ERNW Research GmbH) published a paper about the forensic analysis of APFS, file system internals and presented different methodologies for file recovery. We also publicly released a tool implementing our presented approaches, called afro (APFS file recovery).Continue reading

For those who never heard of Sitefinity before, it is an ASP.NET-based Web Content Management System (WCMS), which is used to deploy and manage applications as other CMS‘s do. A bitter quick glance at Sitefinity and its advantages can be found in this overview.
Delving into the core of this blog post, recently I had the opportunity to look at Sitefinity WCMS in which I found two reflected Cross Site Scripting (XSS) (CVE-2018-17053 and CVE-2018-17056), a stored XSS (CVE-2018-17054) and an arbitrary file upload (CVE-2018-17055) vulnerabilities.Continue reading
Recently, I had some time to play around with HEVD , an extremly vulnerable Windows driver available for 32-bit and 64-bit systems.
Since exploits for all vulnerabilities of the 32-bit variant are publically available, I was wondering why this is not the case for the 64-bit version, especially for the pool corruption and UAF vulnerabilities.Continue reading

Taking a look at the CVE List for WordPress, most vulnerabilities aren’t found within the WordPress core but inside of third-party plugins and themes.
Today, let’s talk about WordPress.
Performing a WordPress assessment might seem boring at first as core functionality [tested] and configuration does not allow for extensive security misconfigurations. Luckily, most instances use plugins and themes to add features not offered by the WordPress core.
In this blog post I would like to discuss the findings and how I discovered them. Also, I will describe different vendor responsiveness reaching from not responding at all, to not understanding the issue to fast and professional responses kindly asking for a review of the updated code ready for deployment.

This blogpost is about the release of a plugin for Binary Ninja that allows you to run a Python Kernel inside the Binary Ninja GUI environment to which you can attach a Jupyer (QT) console, formerly known as IPython shell. The first section is about why this is useful, the second is about some issues I encountered and how to solve them, and the third contains everything you need to know to set it up.
