Remediations

  • The vulnerability identified in this advisory affects versions that are no longer supported. For the Central Monitor CNS-6201, maintenance support in the United States ended in September 2024 (EOS), and maintenance support for the relevant versions has already ended in other countries as well. NIHON KOHDEN recommends users migrate to successor products.
  • If users choose to continue using the CNS-6201 product, ensure the following supplementary controls are strictly implemented under the supervision of a network administrator:
  • Isolate the affected products from the Internet and any untrusted systems.
  • Monitor all network traffic attempting to reach the affected products and log any suspicious activity.
  • If integration with systems such as a Hospital Information System (HIS) is necessary, establish a boundary device (firewall or router) between the physically separated monitoring network and other networks, and explicitly allow only the minimum necessary communications.
  • Ensure monitoring redundancy by using a bedside monitor or medical telemetry system to establish an alternate network connection.
  • For more information, refer to the NIHON KOHDEN product security portal.
