Advisory (ICSMA-18-058-02)

Philips Intellispace Portal ISP Vulnerabilities

Original release date: February 27, 2018


Legal Notice

All information products included in http://ics-cert.us-cert.gov are provided
"as is" for informational purposes only. The Department of Homeland Security
(DHS) does not provide any warranties of any kind regarding any information
contained within. DHS does not endorse any commercial product or service,

OVERVIEW

Philips reported vulnerabilities in the Philips’ IntelliSpace Portal (ISP), an
advanced visualization and image analysis system. Philips is creating a software
update to mitigate these vulnerabilities in the affected products. Additionally,
they are issuing mitigating controls for some vulnerabilities.

Some vulnerabilities could be exploited remotely.

Exploits that target some vulnerabilities are publicly available.


AFFECTED PRODUCTS

Philips reports that these vulnerabilities affect the following versions of the
ISP:

    IntelliSpace Portal, all 8.0.x versions, and IntelliSpace Portal, all 7.0.x
    versions.


IMPACT

Successful exploitation of these vulnerabilities could allow an attacker to gain
unauthorized access to sensitive information, perform man-in-the-middle attacks,
create denial of service conditions, or execute arbitrary code.

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


BACKGROUND

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 ISP processes clinical images from different modalities and enables
advanced visualization of the images. ISP systems are deployed across the
Healthcare and Public Health sectors. Philips estimates these products are used
worldwide.


VULNERABILITY CHARACTERIZATION

VULNERABILITY OVERVIEW

PERMISSIONS, PRIVILEGES, AND ACCESS CONTROLS CWE-264

The ISP has multiple permission, privilege and access control vulnerabilities
that could allow an attacker to gain unauthorized access and in some cases
escalate their level of privilege or execute arbitrary code.

CVE-2018-5472, CVE-2018-5468, CVE-2017-0199, and CVE-2005-1794 have been
assigned to this vulnerability. The CVSS v3 base scores for theses
vulnerabilities range from 6.4 to 7.8

7.8 has been calculated; the CVSS vector string is
(AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

LEFTOVER DEBUG CODE CWE-489

The ISP has a vulnerability where code debugging methods are enabled, which
could allow an attacker to remotely execute arbitrary code during runtime.

CVE-2018-5454 has been assigned to this vulnerability. A CVSS v3 base score of
5.3 has been calculated; the CVSS vector string is
(AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N).

VULNERABILITY DETAILS

EXPLOITABILITY

Some vulnerabilities could be exploited remotely.

EXISTENCE OF EXPLOIT

Public exploits exist for some of these vulnerabilities; however, none are known
to specifically target Philips ISP.

DIFFICULTY

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

MITIGATION

Philips will release an updated version of the ISP in the coming months that
will address these vulnerabilities. Additionally, Philips’ evaluation of
Operating System security patches is ongoing, and after appropriate testing ,
the patches and mitigating controls are posted on Philips’ InCenter. ISP users
are recommended to obtain available mitigating controls by accessing their
InCenter account at this location:

http://incenter.medical.philips.com

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

Philips’ contact information is available at the following location:

https://www.usa.philips.com/healthcare/solutions/customer-service-solutions

Please see the Philips product security website for the latest security
information for Philips products:

NCCIC recommends users take defensive measures to minimize the risk of
exploitation of these vulnerabilities. Specifically, users should:

    Minimize network exposure for all control system 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 measures.

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 website.

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.
