This blog post describes multiple vulnerabilities found in the firmware of Ruckus Unleashed and ZoneDirector. The vulnerabilities were found and reported to CommScope by René Ammerlaan, a guest writer for this blog post. I will take you through all the vulnerabilities and demonstrate how they can be exploited by an attacker.
During Pwn2Own Automotive 2024 in Tokyo, we demonstrated exploits against three different EV chargers: the Autel MaxiCharger (MAXI US AC W12-L-4G), the ChargePoint Home Flex and the JuiceBox 40 Smart EV Charging Station with WiFi. This is our writeup of the research we performed on the Autel MaxiCharger, the bugs we found (CVE-2024-23958, CVE-2024-23959 and CVE-2024-23967) and the exploits we developed. During the competition, we were able to execute arbitrary code on this charger with no other prerequisites than being in range of Bluetooth.
During Pwn2Own Automotive 2024 in Tokyo, we demonstrated exploits against three different EV chargers: the Autel MaxiCharger (MAXI US AC W12-L-4G), the ChargePoint Home Flex and the JuiceBox 40 Smart EV Charging Station with WiFi. This is our writeup of the research that we performed on the JuiceBox 40 Smart EV Charging Station. We discovered one vulnerability which has, since the event, been assigned CVE-2024-23938. During the competition, we were able to exploit CVE-2024-23938 to execute arbitrary code on the charger while requiring only network access for practical reasons at the event. However, being within Bluetooth range of the device is sufficient with a few extra steps.

During the competition, we were able to execute arbitrary code on this charger with no other prerequisites than being in range of Bluetooth.
Computest Sector 7 was asked by Team High-Tech Crime of the Dutch Police to help with writing a decryptor for the DoNex/DarkRace ransomware. DoNex is a relatively new ransomware group, which probably explains why its encryptor contains a simple to abuse mistake. It appears to be the same group that was working under the name DarkRace last year, as the DoNex encryptor we investigated is essentially the same as a DarkRace encryptor we looked at. We have submitted our decryptor to the No More Ransom initiative to help victims recover their files for free.
In the Patch Tuesday update of April 2024, Microsoft released a fix for CVE-2024-20693, a vulnerability we reported. This vulnerability allowed manipulating the cached signature signing level of an executable or DLL. In this post, we’ll describe how we found this issue and what the impact could be on Windows 11.
Last year, we started a project to improve our knowledge of Windows internals, specifically about local vulnerabilities such as privilege escalation. The best way to get started on a new target is to look at recent publications from other researchers. This gives the most up to date overview of the security design, allows looking for variants of the vulnerability or even bypasses for the implemented fixes.
In a previous blog post we described a process injection vulnerability affecting all AppKit-based macOS applications. This research was presented at Black Hat USA 2022, DEF CON 30 and Objective by the Sea v5. This vulnerability was actually the second universal process injection vulnerability we reported to Apple, but it was fixed earlier than the first. Because it shared some parts of the exploit chain with the first one, there were a few steps we had to skip in the earlier post and the presentations. Now that the first vulnerability has been fixed in macOS 13.0 (Ventura) and improved in macOS 14.0 (Sonoma), we can detail the first one and thereby fill in the blanks of the previous post.
