Vulnerabilities in such technologies are highly likely to affect the security of many, if not all, products that use them.
Codesys Runtime Trial Environments AndIn some cases, this means hundreds of products that are used in industrial environments and in critical infrastructure facilities.![]() This is the case with CODESYS Runtime, a framework by CODESYS designed for developing and executing industrial control system software. It should also be noted that the actual adoption figures are much higher, since many vendors PLCs that use the CODESYS Runtime framework are missing from the official list. The number of such devices continues to grow: there were only 140 of them in 2016. We wont be surprised if this trend continues into the future. This enables the developers of a new product to avoid reinventing the wheel, helping reduce development time. We have conducted security research and identified vulnerabilities in third-party code before. For example, in 2017, in part of SafeNet Sentinel, a hardware-based solution designed to control licensing agreement compliance and protect applications from being cracked, and in 2018, in the OPC UA library by OPC Foundation. PLC end-users (i.e., engineers) use the CODESYS development environment to develop the code of industrial process automation programs. In other words, the framework is a sophisticated mechanism that is already in place, and the users code must be designed to be a cog in that mechanism. In it, we address the first two of the above questions: what happens inside the framework and how it works. We also demonstrate a technique for identifying vulnerabilities without being able to analyze the source code. We developed the technical description of CODESYS Runtime provided in this chapter in the process of analyzing the framework. The CODESYS Development System is an IDE used to develop software for controlling devices on which CODESYS Runtime runs. Solutions based on it include IDE SoMachine by Schneider Electric, TwinCAT by Beckhoff Automation, IdraWorks by Bosch, Wagilo Pro by WAGO, IDEs under the name of CODESYS Development System by Owen, STW Technic, and prolog-plc, as well as other IDEs. For CODESYS Runtime to run correctly on a specific device, it has to be adapted to the operating system and hardware selected. According to information on the CODESYS official website, CODESYS developers themselves have only adapted CODESYS Runtime for 15 devices. However, distributors have adapted CODESYS Runtime for over 350 devices. KG, elrest Automationssysteme GmbH, Janz Tec AG, Kendrion Kuhnke Automation GmbH, Beijer Electronics, ifm electronic gmbh, Nidec Control Techniques Limited, Advantech Europe B.V, WAGO Kontakttechnik GmbH Co. KG, KEB Automation KG, Berghof Automation GmbH, and many other vendors. This means that each logical or functional part of CODESYS Runtime is divided into one or more components or modules. Components in this group are responsible for communicating with physical ports and with the file system, for dynamic and static memory allocation, etc.
