Recommendations

Block external access at the network boundary, unless external parties require service.
If global access isn’t needed, block access at the network perimeter to computers hosting the vulnerable device.

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 such as unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.

Implement multiple redundant layers of security.
Use of multiple redundant layers of encryption may reduce exposure to this and other latent vulnerabilities.

Updates are available. Please see the references or vendor advisory for more information.
