Ariele Caltabiano, working with HP’s Zero Day Initiative, has identified 11 remote code execution vulnerabilities in Schneider Electric’s ProClima F1 Bookview ActiveX control application. Schneider Electric has produced an update to mitigate these vulnerabilities.
These vulnerabilities could be exploited remotely.
Schneider Electric reports that the vulnerabilities affect the following versions of ProClima:
These vulnerabilities can be used to modify arbitrary memory and lead to remote code execution.
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.
Schneider Electric’s corporate headquarters is located in Paris, France, and maintains offices in more than 100 countries worldwide.
The affected product, ProClima, is a configuration utility used to design control panel enclosures to accommodate the thermal load from the electrical/electronic devices inside and from the environment. According to Schneider Electric, ProClima is used across several sectors including Critical Manufacturing, Commercial Facilities, and Energy. Schneider Electric estimates that this product is used primarily in the United States and Europe with a small percentage in Asia.
ProClima has 11 vulnerabilities that allow code injection. This could allow the attacker to cause a crash or to execute arbitrary code.

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.
