Philips has identified improper authentication and missing encryption of 
sensitive data vulnerabilities in the Philips Alice 6 System product. Philips
scheduled a new product version release and supporting product documentation 
in December 2018. For all users of the Alice 6 System product, Version R8.0.2
or prior, Philips will update the devices to R8.0.3. This update will 
introduce encryption of data in transit and at rest, and stop transmission of
clear text usernames and passwords.


The following versions of the 6 System are affected:

    Version R8.0.2 or prior.


Successful exploitation may allow an attacker to gain visibility to 
usernames/passwords and personal data. Insufficient encryption and 
cryptographic integrity checks can lead to altered, corrupted, or disclosed 
sensitive data. Disclosure of personal data can occur by replacing a trusted 
node with a malicious node.

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


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

The affected product, Philips AliceNe 6, is a Polysomnography System (PSG) that
is intended to record, display, and print physiological information to 
clinicians/physicians. According to Philips, Alice 6 is deployed across the 
Healthcare and Public Health sectors. Philips estimates this product is used 
in 50 countries around the world, including the United States and other 
countries within Asia Pacific, Europe, the Middle East, and North America.




When an actor claims to have a given identity, the software does not prove or
insufficiently proves that the claim is correct. This weakness can lead to the
exposure of resources or functionality to unintended actors, possibly 
providing attackers with sensitive information or the ability to execute 
arbitrary code.

CVE-2018-5451 has been assigned to this vulnerability. A CVSS v3 base score of
5.3 has been calculated; the CVSS vector string is 


The lack of proper data encryption passes up the guarantees of 
confidentiality, integrity, and accountability that properly implemented 
encryption conveys.

CVE-2018-7498 has been assigned to this vulnerability. A CVSS v3 base score of
5.3 has been calculated; the CVSS vector string is 



These vulnerabilities could be exploited remotely.


Exploits that target these vulnerabilities are publicly available.


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


Philips will notify users of the identified vulnerabilities and will 
coordinate with the users to schedule updates. Philips is scheduled to release
a new product version and supporting product documentation in December 2018. 
For all users of the Alice 6 System product, version R8.0.2 or prior, Philips
will update the devices to R8.0.3. Philips encourages users to use Philips 
validated and authorized changes only for the Alice 6 device supported by 
Philips authorized personnel or under Philips explicit published directions 
for patches, updates, or releases.

As an interim mitigation to the vulnerabilities until the update can be 
applied, Philips recommends that users:

    Ensure that network security best practices are implemented, and

    Limit network access to Alice 6 in accordance with product documentation.

Users with questions regarding their specific Alice 6 installations should 
contact their local Philips service support team or their regional Alice 6 
service support. Contact information is available at the following location:

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

    Ensure that non-product related software packages, such as email and web 
browser software, are not installed on medical devices, as they could contain
vulnerabilities, malware, and broaden the attack surface, which could impact 
the intended function of the device.

    Minimize network exposure for all control system devices and/or systems; 
ensure that they are not accessible from the Internet.

    Locate all medical devices and remote devices behind firewalls; 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 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.
