Independent security researcher Marcus Richerson and Steven Seeley of Source Incite, working with Trend Micro’s Zero Day Initiative, independently identified vulnerabilities in Ecava’s IntegraXor application. Ecava has produced a new version to mitigate these vulnerabilities. Marcus Richerson has tested the new version to validate that it resolves all the vulnerabilities, except for one incomplete fix, which Ecava plans to fully address in an upcoming release.
These vulnerabilities could be exploited remotely.
Exploits that target these vulnerabilities are known to be publicly available.
The following Ecava IntegraXor versions are affected:
Successful exploitation of these vulnerabilities may allow a remote attacker to gain full access to an affected system.
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.
Ecava Sdn Bhd (Ecava) is a Malaysia-based software development company that provides the IntegraXor SCADA product. Ecava specializes in factory and process automation solutions.
The affected product, IntegraXor, is a suite of tools used to create and run a web-based human‑machine interface for a SCADA system. According to Ecava, IntegraXor is deployed across several sectors including Critical Manufacturing, Energy, Water and Wastewater Systems, and others. Ecava estimates that this product is used in multiple countries, with the largest installations based in the United Kingdom, the United States, Australia, Poland, Canada, and Estonia.
