CVSS v3 7.3

ATTENTION: Remotely exploitable/low skill level to exploit.

Vendor: Fuji Electric

Equipment: Monitouch V-SFT

Vulnerabilities: Stack-Based Buffer Overflow, Heap-Based Buffer Overflow,
Improper Privilege Management


The following versions of Monitouch V-SFT, a screen configuration software,
are affected:

    Monitouch V-SFT, versions prior to Version


Successful exploitation of these vulnerabilities could allow remote code
execution or cause the software that the attacker is accessing to crash. The
improper privilege management vulnerability could allow an attacker with
local access to escalate privileges.


Fuji Electric has released a new version of Monitouch V-SFT, Version, to fix these vulnerabilities. Users can download the update at

NCCIC/ICS-CERT recommends that 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 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 reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.

ICS-CERT also provides a section for control systems security recommended
practices on the ICS-CERT web page. 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 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.
