Boston Scientific ZOOM LATITUDE PRM Vulnerabilities
Original release date: October 19, 2017

OVERVIEW

Researchers Jonathan Butts and Billy Rios of Whitescope have
identified two vulnerabilities in Boston Scientific's ZOOM LATITUDE
Programmer/Recorder/Monitor (PRM) - Model 3120. Boston Scientific has
provided compensating controls to reduce the risk of exploitation.
AFFECTED PRODUCTS

The following ZOOM LATITUDE PRM versions are affected:

    ZOOM LATITUDE PRM - Model 3120, all versions.

IMPACT

Successful exploitation of these vulnerabilities may allow an attacker with
physical access to obtain patient health information (PHI). The affected
device is not designed to be network accessible.

Impact to individual organizations depends on many factors that are unique
to each organization. NCCIC/ICS-CERT recommends that organizations evaluate
the impact of these vulnerabilities based on their operational environment
and specific clinical usage.

BACKGROUND

Boston Scientific is a US-based company that is headquartered in Marlborough,
Massachusetts.

The affected products, ZOOM LATITUDE PRMs, are portable cardiac rhythm
management systems used to communicate with implanted pacemakers and
defibrillators. According to Boston Scientific, ZOOM LATITUDE PRMs are
deployed across the Healthcare and Public Health sector. Boston Scientific
asserts that these products are used worldwide.

VULNERABILITY CHARACTERIZATION

VULNERABILITY OVERVIEW

USE OF HARD-CODED CRYPTOGRAPHIC KEY(a)

The affected device uses a hard-coded cryptographic key to encrypt PHI
prior to having it transferred to removable media.

CVE-2017-14014(b) has been assigned to this vulnerability. A CVSS
v3 base score of 4.6 has been assigned; the CVSS vector string is
(AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).(c)

MISSING ENCRYPTION OF SENSITIVE DATA(d)

The affected device does not encrypt PHI at rest.

CVE-2017-14012(e) has been assigned to this vulnerability. A CVSS
v3 base score of 4.6 has been assigned; the CVSS vector string is
(AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).(f)

VULNERABILITY DETAILS

EXPLOITABILITY

These vulnerabilities are not remotely exploitable and require physical
access.

EXISTENCE OF EXPLOIT

No known public exploits specifically target these vulnerabilities.

DIFFICULTY

An attacker with a low skill would be able to exploit these vulnerabilities.

MITIGATION

Boston Scientific will not be issuing a product update to address the
identified vulnerabilities in the ZOOM LATITUDE PRM - Model 3120. Boston
Scientific has identified compensating controls to reduce the risk of
exploitation and recommends that users implement the following measures:

    Control access to the device and ensure all access is properly
    inventoried,
    Maintain the device in a secure or locked location when not in use, and
    Remove PHI prior to retiring or removing the device from the
    facility. Instructions for removing PHI are outlined in the operator's
    manual.

ICS-CERT also provides a section for security
recommended practices on the ICS-CERT web page at
http://ics-cert.us-cert.gov/content/recommended-practices. ICS-CERT reminds
organizations to perform proper impact analysis and risk assessment prior
to deploying defensive measures.

Additional mitigation guidance and recommended practices are
publicly available in the ICS-CERT Technical Information Paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies, that is available for download from the ICS-CERT web site
(http://ics-cert.us-cert.gov/).

Organizations observing any suspected malicious activity should follow their
established internal procedures and report their findings to ICS-CERT for
tracking and correlation against other incidents.
