RTFM: Read The Fatal Manual – When Vendor Documentation Creates Critical Attack Paths

Sicherheitsmeldung mit Schweregrad noch nicht bewertet. Betroffene Kennungen: CVE-2026-0872. Technische Details im Tab „Originaltext“; empfohlene Schritte in der Checkliste.

Originaltext der Quelle (nicht übersetzt) – die deutsche Zusammenfassung findest du im Tab „Kurzfassung".

TL;DR: Trusted vendor documentation across 16 major technology companies were actively guiding administrators to deploy critical misconfigurations (often Active Directory Certificate Services) – a misconfiguration known by the community for over four years. These documentation flaws create attack paths that can be worse than traditional CVE-worthy bugs. Through responsible disclosure, some vendors fixed issues within a month, while others remained unresolved months later. Key lesson: never trust vendor documentation blindly – always conduct security reviews before and after implementation, especially for Tier Zero infrastructure like PKI.

Introduction

Despite years of widespread awareness, critical misconfigurations continue to appear in enterprise environments worldwide. Through extensive research, I discovered that public documentation from trusted vendors actively guided users to deploy these misconfigurations. I responsibly reported my findings to all affected vendors.

My research focused primarily on Active Directory Certificate Services (AD CS) misconfigurations: a vulnerability class my colleagues Will Schroeder and Lee Christensen discovered in their “Certified Pre-Owned” blog post and whitepaper, published over four years ago.

This blog post presents, in order: the mis-documentation problem, gives key takeaways, summarizes the responsible disclosure process and vendor timeline, and then the last section is documentation of all findings including demonstrating the associated risks and recommendations.

As I was finalizing this research and preparing to notify …
