Description

The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions in the Conexus Radio Frequency Telemetry Protocol. A remote attacker on the local network, when the product’s radio is turned on, can inject, replay, modify, and/or intercept data within the telemetry communication. This communication protocol provides the ability to read and write memory values to affected implanted cardiac devices; therefore, an attacker could exploit this communication protocol to change memory in the implanted cardiac device.


Remediation

Vendor has developed mitigating patches for the following products:

  • Brava CRT-D, all models                                            
  • Evera MRI ICD, all models
  • Evera ICD, all models
  • Mirro MRI ICD, all models
  • Primo MRI ICD, all models
  • Viva CRT-D, all models

These patches are installed during regular office visits.
