Recommendation
Apply vendor updates, restrict physical access to USB ports, and monitor connected devices.
Original NVD description (English source)
A vulnerability in the USB driver of Cisco RoomOS could allow an unauthenticated, local attacker with physical access to the USB port on an affected device to execute arbitrary code with root privileges. This vulnerability is due to insufficient boundary checks for specific data that is provided through the USB driver. An attacker could exploit this vulnerability by connecting a malicious USB device to an affected device. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected system and execute arbitrary code with root privileges.
