Advisories

As the DriveLock Enterprise Service version 25.2.4.62569 released on 2026-02-20 includes patches for other vulnerabilites I submitted to the vendor - ZDI-CAN-28726, ZDI-CAN-28713 / ZDI-CAN-28722 / ZDI-CAN-28746, ZDI-CAN-28719 - I did a patch analysis if the applied mitigations can be bypassed somehow.

At a first glance it seems that the patches can not be bypassed.

But having a closer look at the patch-diff reveleaed that the patch also closes security vulnerabilites not mentioned on the patch notes.

This post gives you an overview about these silently patched vulnerabilites and a working Proof of Concept.
