Version Summary:Multiple vendor medical devices contain a vulnerability that could allow an unauthenticated, remote attacker to bypass security restrictions to the targeted device. Updates are not available.
 

Description
 
A vulnerability in a wide range of medical devices from multiple vendors could allow an unauthenticated, remote attacker to bypass security restrictions to the targeted device.

The vulnerability is due to hard-coded account credentials in the device firmware. An unauthenticated, remote attacker with knowledge of these credentials could exploit this vulnerability to gain unauthorized access to the targeted device. A successful exploit could allow the attacker to access sensitive information, change critical settings, or modify device firmware.

Reports indicate that functional exploit code exists; however, it is not known to be publicly available.

ICS-CERT has released a security advisory at the following link: ICS-ALERT-13-164-01

The U.S. Food and Drug Administration (FDA) has released a safety communication at the following link: FDA Safety Communication: Cybersecurity for Medical Devices and Hospital Networks

The vulnerability affects a wide range of medical devices from multiple vendors including, but not limited to the following:
  • Surgical and anesthesia devices
  • Ventilators
  • Drug infusion pumps
  • External defibrillators
  • Patient monitors
  • Laboratory and analysis equipment
Updated software was not available at the time this alert was first published.

Administrators are advised to contact the vendor regarding future updates and releases.

Administrators are advised to allow only trusted users to access local systems and devices.

Administrators are advised to allow only trusted users to have network access.

Administrators are advised to allow only privileged users to access administration, management, or critical systems and devices.

Administrators are advised to monitor affected systems.

It is critical to prevent unauthorized direct communication to network devices. Restrict network traffic destined for the network infrastructure to protect against reconnaissance and denial-of-service (DoS) attacks. For configuration details, see Protecting Your Core: Infrastructure Protection Access Control Lists.

Understanding activity on the network provides information and visibility that can be used to identify potential security incidents. Organizations should log events from devices and review the logged data to provide insight into anomalies or malicious activity. For logging best practices, see the Cisco Guide to Harden Cisco IOS Devices.

Network traffic should be monitored for security-related network activity. NetFlow identifies security-related network activity. For NetFlow configuration details, see the Introduction to Cisco IOS NetFlow - A Technical Overview.
