adcs-template-abuse

adcs-template-abuse is a skill for Claude Code, Codex from blacklanternsecurity/red-run. It costs 69 tokens per session (4,349 once invoked), scanned A, original, GPL-3.0.

A set of techniques for abusing misconfigured AD CS certificate templates, which define who can request certificates and what those certificates may represent. Some unsafe templates can allow a requester to act as another domain user.

In plain words
What is it for?
For checking ESC1, ESC2, ESC3 and ESC6 conditions, including user-supplied subjects, unrestricted usage, enrollment agents and CA subject-name flags.
Why use it?
It helps reveal certificate-request settings that allow impersonation through subject-name changes or enrollment-agent permissions.

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

adcs-template-abuse scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
