Microsoft warns of industrial control system security risks: loopholes may lead to devastating consequences

Recently, Microsoft network security experts issued an important security bulletin, revealing a series of high-risk vulnerabilities found in the development tools of programmable logic controllers (PLC). The potential harm of these vulnerabilities is huge and can be exploited by malicious attackers to cause serious damage or even cause the outage of critical infrastructure such as power plants.

Microsoft threat analyst Vladimir Tokarev discovered this issue in the CODESYS V3 SDK . CODESYS V3 SDK is widely used in the industrial field and has been used to develop millions of PLC controllers. The vulnerabilities are rated as high-risk vulnerabilities, with scores ranging from 7.5 to 10 out of 10, indicating their serious threat

According to reports, CVE-2022-47379 Tracking numbers have been identified for these vulnerabilities. Microsoft urges all developers using CODESYS to immediately upgrade to version 3.5.19.0 or higher to fix these vulnerabilities and ensure system security

In the face of the threat of these vulnerabilities, experts have made some suggestions to reduce the potential risk. Microsoft recommends isolating the SPS (Programmable Logic Controller) and its associated infrastructure from the Internet to reduce the possibility of potential attacks. In addition, to help engineers and administrators better discover vulnerable devices, Microsoft 365 Defender has also released a free software tool to enhance the overall security of the system

As industrial automation technology further advances With the development, the criticality of PLC controller has become more important. However, this also provides opportunities for malicious attackers to find and exploit vulnerabilities. It is understood that this incident reminds us that protecting the security of industrial control systems is crucial and requires joint efforts at the technical, policy and practical levels to ensure the stable and safe operation of critical infrastructure
