The Department of Homeland Security (DHS) does not provide any warranties of any kind regarding any information contained within.

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.
