# ADCS abuse (ESC1–ESC8)
## When it applies
The domain runs Active Directory Certificate Services and you have any authenticated foothold.
Misconfigured certificate templates or CA settings let a low-priv user obtain a certificate that
authenticates as a privileged account — a fast, reliable path to Domain Admin.
## Why it works
Certificates can be used for Kerberos (PKINIT) authentication. If a template lets an enrollee
specify the subject (SAN) and permits client-auth, a normal user can request a cert *as* Domain
Admin. Other ESCs abuse enrollment-agent rights, vulnerable CA ACLs, NTLM relay to the CA
(ESC8), or the CA cert's private key.
