AI-Generated

A vulnerability in the USB driver of Cisco RoomOS allows unauthenticated local attackers with physical access to execute arbitrary code with root privileges by connecting a malicious USB device. This issue arises from insufficient boundary checks for data processed through the USB driver, potentially leading to a buffer overflow. Organizations using affected Cisco devices should prioritize remediation to mitigate the risk of unauthorized access and control.

Original NVD Description

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.
