Evgeny Druzhinin, Alexey Osipov, Ilya Karpov, and Gleb Gritsai of Positive Technologies have identified several vulnerabilities in Inductive Automation’s Ignition Software. Inductive Automation has produced a patch that mitigates these vulnerabilities.
These vulnerabilities could be exploited remotely.
The following Inductive Automation product is affected:
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.
Inductive Automation is a Folsom, California-based supplier of web-based industrial automation software.
The affected product, Ignition, is an updated version of FactoryPMI, offered by Inductive Automation. Ignition is a human-machine interface/SCADA product used in a variety of industrial applications. According to Inductive Automation, Ignition is deployed across several sectors including Communications, Energy, Food and Agriculture, and Water and Wastewater Systems. Inductive Automation estimates that this product is used primarily in North and South America, Europe, Australia, and across Asia.
An attacker may cause dangerous content to be executed through a vulnerable web application. The server reads data directly from the HTTP request and reflects it back in the HTTP response.

These vulnerabilities are not exploitable remotely and cannot be exploited without user interaction. The exploit is only triggered when a local user runs the vulnerable application and loads the malformed URL to the JNLP.
Exploits that target these vulnerabilities are not publicly available.
An attacker with a low skill would be able to exploit these vulnerabilities.
Inductive Automation has developed a patch for these vulnerabilities and recommends updating as soon as possible. The patch is available at:
<https://www.inductiveautomation.com/downloads/ignition>
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.
