Philips reported an insufficient session expiration vulnerability in
the Philips' IntelliSpace Cardiovascular cardiac image and information
management systems. Philips is creating a software update to mitigate this
vulnerability in the affected products.


Philips reports that the vulnerability affects the following versions of
the IntelliSpace Cardiovascular:

    IntelliSpace Cardiovascular, Version 2.3.0 and prior.


Successful exploitation of this vulnerability could allow an attacker to
gain unauthorized access to sensitive information stored on the system
and modify this information.

Impact to individual organizations depends on many factors that are unique
to each organization. NCCIC recommends that organizations evaluate the
impact of this vulnerability based on their operational environment and
specific clinical usage.


Philips is a global company that maintains offices in many countries around
the world, including countries in Africa, Asia, Europe, Latin America,
the Middle East, and North America.

The Philips IntelliSpace Cardiovascular (ISCV) is both a comprehensive
cardiac image and information management system.

According to Philips, ISCV cardiac image and information management systems
are deployed across the Healthcare and Public Health sector. Philips
estimates this product is used worldwide.




The ISCV application has an insufficient session expiration vulnerability
where an attacker could reuse the session of a previously logged in
user. This vulnerability exists when using ISCV together with an Electronic
Medical Record (EMR) system, where ISCV is in KIOSK mode for multiple
users and using Windows authentication. This may allow an attacker to gain
unauthorized access to patient health information and potentially modify
this information.

CVE-2018-5438 has been assigned to this vulnerability. A CVSS v3
base score of 6.7 have been assigned; the CVSS vector string is



This vulnerability is exploitable via local access.


No known public exploits specifically target this vulnerability.


An attacker with a low skill level would be able to exploit this


Philips is adding an additional configuration option to ISCV 3.1. The
option to not use Windows authentication when communicating with an EMR
in KIOSK mode will become available in this release. Philips is in the
process of releasing this version in the coming months.

Users with questions regarding their specific IntelliSpace Cardiovascular
installations are advised by Philips to contact their local Philips
service support team or their regional service support. Philips' contact

NCCIC recommends that users take defensive measures to minimize the risk
of exploitation of this vulnerability. Specifically, users should:

    Minimize network exposure for all medical devices and/or systems,
    and ensure that they are not accessible from the Internet.
    Locate all medical devices and remote devices behind firewalls, and
    isolate them from the business network.
    When remote access is required, use secure methods, such as Virtual
    Private Networks (VPNs), recognizing that VPNs may have vulnerabilities
    and should be updated to the most current version available. Also
    recognize that VPN is only as secure as the connected devices.

NCCIC also provides a section for control systems security recommended
practices on the ICS-CERT web page. NCCIC reminds organizations to perform
proper impact analysis and risk assessment prior to deploying defensive

Additional mitigation guidance and recommended practices are
publicly available in the NCCIC 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.

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