Securing Windows Interprocess Communication
Named pipes in Windows facilitate interprocess communication but pose significant security challenges. The article outlines vulnerabilities, highlighting that many developers incorrectly assume their local communication is trusted due to the processes running on the same machine. Key points include the importance of strictly defining pipe permissions, separating authentication from authorization, and verifying client-server identities to prevent potential exploitation by malicious actors.

Summary
TL;DR
- Named pipes enable fast interprocess communication but are often misconfigured.
- Vulnerabilities arise when privileged services connect with less-privileged applications.
- Authentication and authorization should be treated as separate processes.
- Broad pipe permissions can allow unauthorized access from unrelated processes.
- The pipe must be seen as a potential entry point for attacks.
Interesting facts
- Named pipes can support remote access under certain configurations, contrary to common assumptions.
- Misconfigured permissions can turn named pipes into a mechanism for privilege escalation.
