ZDI (Zero Day Initiative) has identified one information disclosure and two buffer overflow vulnerabilities, and independent researcher Jeremy Brown has identified hard-coded credentials in Pro-face’s GP-Pro EX HMI software. Pro-face has produced a module to mitigate these vulnerabilities.
These vulnerabilities could be exploited remotely, and some can be exploited without user interaction.
Pro-face reports that these vulnerabilities affect the following versions of GP-Pro EX:
It is possible for an attacker to force a stack-based buffer overflow. An attacker can leverage these vulnerabilities to execute arbitrary code in the context of the process.
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.
Pro-face is a US-based company that maintains offices in several countries around the world, including Asia, India, Australia, the Americas, and Europe. Schneider Electric has recently acquired Pro-face.
The affected product, GP-Pro EX, is an HMI Screen Editor and Logic Programing software. According to Pro-face, GP-Pro EX is deployed across several sectors including Commercial Facilities, Critical Manufacturing, Energy, Water and Wastewater Systems, and others. Pro-face estimates that this product is used worldwide.
It is possible for an attacker to force a heap-based buffer overflow. An attacker can leverage this vulnerability to execute arbitrary code in the context of the process.

ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
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 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.
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 (http://ics-cert.us-cert.gov/).
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.
In addition, ICS-CERT recommends that users take the following measures to protect themselves from social engineering attacks:
