Successful exploitation of these vulnerabilities may allow an attacker unauthorized access to the IntelliBridge EC40 and80 Hub. This could allow an attacker to execute software, modify system configurations, or view/update files, including unidentifiable patient data.
The following versions of IntelliBridge are affected:
The software contains hard-coded credentials, such as a password or a cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data.
CVE-2021-32993 has been assigned to this vulnerability. A CVSS v3 base score of 8.1 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H).
The standard access path of the affected product requires authentication, but the product has an alternate path or channel that does not require authentication.
CVE-2021-33017 has been assigned to this vulnerability. A CVSS v3 base score of 8.1 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H).
Younes Dragoni, Andrea Palanca and Ivan Speziale of Nozomi Networks reported these vulnerabilities to CISA.
Philips plans to make a new release to remediate these vulnerabilities by the end of Q4 2021.
As an interim mitigation to these vulnerabilities, Philips recommends the following:
Users with questions about their specific EC 40 and EC 80 Hub products should contact the Philips service support team or regional service support. Philips contact information is available on the Philips customer service solutions website, or via phone (U.S.) at 1-800-722-9377.
The IntelliBridge EC 40 and EC 80 Hub is intended to transfer medical device data from one format to another according to preset specifications. It performs data transfer without controlling or altering the function or parameters of any connected medical devices. The EC 40 and EC 80 Hub are not intended for use in connection with active patient monitoring. If data is not received from the hub a notification is generated on the PIC iX Central Station and users are advised to refer to the source medical device.
More information on these vulnerabilities, as well as the latest security information for Philips products, is available on the Philips product security website.
CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on us-cert.cisa.gov. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage on us-cert.cisa.gov in the Technical Information Paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.
No known public exploits specifically target these vulnerabilities. These vulnerabilities are not exploitable remotely.
