Exploiting Logic Errors and Race Conditions in Windows RPC Servers: A Case Study Approach

# RPC Bug Hunting Case Studies ## Introduction - What is RPC and why it is important for Windows security - How RPC servers can be vulnerable to privilege escalation attacks - What tools and techniques can be used to find and exploit RPC bugs ## Case Study 1: Windows Task Scheduler - How SandboxEscaper discovered and published a zero-day exploit for a logic error in the Task Scheduler RPC server - How FortiGuard Labs analyzed the exploit and found similar vulnerabilities in other RPC servers - How to use RPCView to identify and audit RPC APIs that accept strings as input parameters ## Case Study 2: Data Sharing Service - How Google Security Researcher James Forshaw reported four vulnerabilities in the Data Sharing Service RPC server - How FortiGuard Labs used a different approach to find this service and its flaws - How to create a static analysis tool that parses RPC service executables and looks for Windows APIs of interest ## Case Study 3: Storage Service and AppX Deployment Server - How FortiGuard Labs reported two vulnerabilities in the Storage Service and AppX Deployment Server RPC servers - How to exploit a race condition that allows arbitrary file deletion or DACL modification - How to use symbolic links and hard links to escalate privileges ## Conclusion - Summary of the main points and findings of the article - Recommendations for security researchers and developers to prevent or mitigate RPC bugs - Future directions for RPC bug hunting research ## FAQs - What is the difference between local and remote RPC servers? - What are some common types of RPC bugs? - What are some best practices for writing secure RPC code? - What are some other tools or resources for learning more about RPC? - How can I report a potential RPC vulnerability to Microsoft?
