Descriptions

In its default configuration, the affected product transmits plain-text patient data to a hard-coded public IP address when a patient is hooked up to the monitor. This could lead to a leakage of confidential patient data to any device with that IP address or an attacker in a machine-in-the-middle scenario.

In its default configuration, Contec Health CMS8000 Patient Monitor transmits plain-text patient data to a hard-coded public IP address when a patient is hooked up to the monitor. This could lead to a leakage of confidential patient data to any device with that IP address or an attacker in a machine-in-the-middle scenario.

This fact sheet details an analysis of three firmware package versions of the Contec CMS8000, a patient monitor used by the U.S. Healthcare and Public Health (HPH) sector. Analysts discovered that an embedded backdoor function with a hard-coded IP address and functionality that enables patient data spillage exists in all versions analyzed.
