Microsoft Windows IP-HTTPS Server Revoked SSL Certificate Validation Security Bypass Vulnerability

Microsoft Windows is prone to a security-bypass vulnerability that affects the IP-HTTPS server component.

Successful exploits may allow attackers to perform man-in-the-middle attacks or impersonate trusted clients, which will aid in further attacks.

To exploit this issue an attacker must possess a certificate issued from the domain and be able to intercept network traffic between a legitimate client, that connects to a vulnerable application, and the server.
