Omron NS Series HMI Vulnerabilities

Original release date: July 22, 2014

Researcher Joel Sevilleja Febrer of S2 Grupo has identified multiple
vulnerabilities in Omron Corporation's NS series human-machine interface
(HMI) terminals. Omron Corporation has produced an update that mitigates
these vulnerabilities.

These vulnerabilities could be exploited remotely.


The following Omron Corporation products are affected:

    NS15 Version 8.1xx - 8.68x,
    NS12 Version 8.1xx - 8.68x,
    NS10 Version 8.1xx - 8.68x,
    NS8 Version 8.1xx - 8.68x, and
    NS5 Version 8.1xx - 8.68x.


Successful exploitation of these vulnerabilities could allow an attacker
to modify device configuration and expose sensitive information.

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,
architecture, and product implementation.


Omron Corporation is an international company headquartered in Kyoto, Japan.

The affected products are NS series HMI terminals. According to Omron
Corporation, NS series HMI terminals are marketed globally; however,
Omron states the vulnerabilities only affect their overseas market. The
NS series HMI terminals are deployed across several sectors including
Critical Manufacturing and Healthcare and Public Health.




The web application receives a request from a client without adequately
verifying that the request was intentionally sent. This could allow an
attacker to execute commands thereby compromising the system and enabling
modifications to the system's configuration.

CVE-2014-2369[b] has been assigned to this vulnerability. A CVSS
v2 base score of 4.6 has been assigned; the CVSS vector string is


The web application stores untrusted data that are read back into the
application and included in dynamic content.

CVE-2014-2370[e] has been assigned to this vulnerability. A CVSS
v2 base score of 4.0 has been assigned; the CVSS vector string is



These vulnerabilities could be exploited remotely.


No known public exploits specifically target these vulnerabilities.


An attacker with a high to moderate skill would be able to exploit these


Omron Corporation has produced update, Version 8.69x for Japan and Version
8.7x for other countries, that mitigates the identified vulnerabilities. The
updates for the NS series of HMI terminals can be downloaded at the
following locations:

ICS-CERT encourages asset owners to take additional defensive measures to
protect against this and other cybersecurity risks.

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

ICS-CERT also provides a section for control systems
security recommended practices on the ICS-CERT web page at:
http://ics-cert.us-cert.gov/content/recommended-practices. Several
recommended practices are available for reading and download, including
Improving Industrial Control Systems Cybersecurity with Defense-in-Depth
Strategies. 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

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.
