GPP cPassword Attack

What is GPP?

  • Group policies preferences allowed admins to create policies using embedded credentials.

  • These credentials were encrypted and placed in a "cPassword"

Why is vulnerable?

  • The key was accidentally released by Microsoft

  • Patched in MS14-025 but doesn't prevent previous uses.

  • The key was stored in SYSVOL

  • Any Domain User can read the policy
