Date Discovered December 11, 2012
Description 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.
- Microsoft Windows Server 2008 R2 Itanium
- Microsoft Windows Server 2008 R2 Itanium SP1
- Microsoft Windows Server 2008 R2 for x64-based Systems
- Microsoft Windows Server 2008 R2 for x64-based Systems SP1
- Microsoft Windows Server 2012
Block external access at the network boundary, unless external parties require service. If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and
networks might greatly reduce the likelihood of exploits.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.
Updates are available. Please see the references for details.
