My daily read on upcoming and in the know for trusted news on IT Vulnerability News. I am sure we have a lot of Supermicro boards running "B11, CMM, H11, H12, M11, and X11 motherboards." From one security point, if your systems are exposed to the Internet, please consider network limitations to access from a secure resource to your BMC/IPMI interfaces if possible. Maintain your "Human Firewall" and watch what you click on.
