Detail

Revision Note: V1.0 (December 11, 2012): Bulletin published.

Summary: This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow security feature bypass if an attacker presents a revoked certificate to an IP-HTTPS server commonly used in Microsoft DirectAccess deployments. To exploit the vulnerability, an attacker must use a certificate issued from the domain for IP-HTTPS server authentication. Logging on to a system inside the organization would still require system or domain credentials.
