Raising the Dead

A Project Zero post explains how arbitrary file write bugs on Windows can be turned into local privilege escalation, walking through practical exploitation techniques for this bug class.

A Project Zero post in the Windows exploitation tricks series, showing how an arbitrary directory creation primitive can be escalated into arbitrary file read.

A bug in the Windows Secondary Logon service, fixed as MS16-032, leaks a fully accessible thread handle from a privileged process, enabling privilege escalation without memory corruption.

Analyzing the attack surface of user-mode sandboxed applications helps find elevation of privilege bugs; automating the enumeration matters for initial analysis and detecting regressions.

A bug in the TrueCrypt Windows driver, despite prior security audits, lets a normal user or low-integrity sandbox remap the main system drive and elevate privileges to SYSTEM or kernel.

Years of Windows elevation of privilege research distilled into an overview of symbolic link mitigations, a technique long used to redirect privileged code and escape restricted execution contexts.
