Tens of thousands of servers worldwide powered by Supermicro motherboards are affected by a vulnerability that would allow an attacker to remotely take over them. Researchers at firmware security firm Eclypsium discovered multiple vulnerabilities referred as USBAnywhere that could be exploited to potentially take over the baseboard management controller (BMC) for three different models of Supermicro server boards: the X9, X10, and X11. At the time of publishing, researchers found at least 47,000 systems with their BMCs exposed to the Internet.”]
