Supermicro BMC
CVE-2019-16650
On Supermicro X10 and X11 products, a client's access privileges may be transferred to a different client that later has the same socket file descriptor number. In opportunistic circumstances, an attacker can simply connect to the virtual media service, and then connect virtual USB devices to the server managed by the BMC.
