Synopsis :

The remote Windows host is affected by a security feature bypass

Description :

A security feature bypass vulnerability exists in Windows due to the
way the IP-HTTPS Component handles certificates. 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, the attacker
must use a certificate issued from the domain for IP-HTTPS server

Successful exploitation of this vulnerability could allow the attacker
to bypass certificate validation checks. Logging on to a system inside
the organization would still require system or domain credentials.
