CVE-2010-0237 The Windows Registry Adventure #7: Attack surface analysis - Project Zero
Posted by Mateusz Jurczyk, Google Project Zero
In the first three blog posts of this series, I sought to outline what the Windows Registry actually is, its role, history, and where to find further information about it. In the subsequent three posts, my goal was to describe in detail how this mechanism works internally – from the perspective of its clients (e.g., user-mode applications running on Windows), the regf format used to encode hives, and finally the kernel itself, which contains its canonical implementation. I believe all these elements are essential for painting a complete picture of this subsystem, and in a way, it shows my own approach to security research. One could say that going through this tedious process of getting to know the target unnecessarily lengthens the total

CVE-2015-0073 The Windows Registry Adventure #5: The regf file format - Project Zero
Posted by Mateusz Jurczyk, Google Project Zero
As previously mentioned in the second installment of the blog post series ("A brief history of the feature"), the binary format used to encode registry hives from Windows NT 3.1 up to the modern Windows 11 is called regf. In a way, it is quite special, because it represents a registry subtree simultaneously on disk and in memory, as opposed to most other common file formats. Documents, images, videos, etc. are generally designed to store data efficiently on disk, and they are subsequently parsed to and from different in-memory representations whenever they are read or written. This seems only natural, as offline storage and RAM come with different constraints and requirements. On disk, it is important that the data is packed as tightly as

CVE-2023-35356 The Windows Registry Adventure #4: Hives and the registry layout - Project Zero
Posted by Mateusz Jurczyk, Google Project Zero
To a normal user or even a Win32 application developer, the registry layout may seem simple: there are five root keys that we know from Regedit (abbreviated as HKCR, HKLM, HKCU, HKU and HKCC), and each of them contains a nested tree structure that serves a specific role in the system. But as one tries to dig deeper and understand how the registry really works internally, things may get confusing really fast. What are hives? How do they map or relate to the top-level keys? Why are some HKEY root keys pointing inside of other root keys (e.g. HKCU being located under HKU)? These are all valid questions, but they are difficult to answer without fully understanding the interactions between the user-mode Registry API and the kernel-mode registr

CVE-2022-34707 The Windows Registry Adventure #1: Introduction and research results - Project Zero
Posted by Mateusz Jurczyk, Google Project Zero
In the 20-month period between May 2022 and December 2023, I thoroughly audited the Windows Registry in search of local privilege escalation bugs. It all started unexpectedly: I was in the process of developing a coverage-based Windows kernel fuzzer based on the Bochs x86 emulator (one of my favorite tools for security research: see Bochspwn, Bochspwn Reloaded, and my earlier font fuzzing infrastructure), and needed some binary formats to test it on. My first pick were PE files: they are very popular in the Windows environment, which makes it easy to create an initial corpus of input samples, and a basic fuzzing harness is equally easy to develop with just a single GetFileVersionInfoSizeW API call. The test was successful: even though I h
