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 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.

NCCIC reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

NCCIC 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 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.

No known public exploits specifically target this vulnerability. This vulnerability is not exploitable remotely. High skill level is needed to exploit.



An uncontrolled search path element (DLL Hijacking) vulnerability has been identified. To exploit this vulnerability, an attacker could rename a malicious DLL to meet the criteria of the application, and the application would not verify that the DLL is correct. Once loaded by the application, the DLL could run malicious code at the privilege level of the application.

CVE-2017-14020 has been assigned to this vulnerability. A CVSS v3 base score of 6.7 has been assigned; the CVSS vector string is (AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H).
