- Advisory2024-05_VDE-2024-057CODESYS: CODESYS web server vulnerable to DoS2024-09-25csaf · codesys_psirtDE
The CODESYS web server component of the CODESYS Control runtime system is used by the CODESYS WebVisu to display visualization screens in a web browser. Receiving a specifically crafted TLS packet on an HTTPS connection causes the CODESYS web server to crash because the return value of an underlying function is not checked correctly for such unusual conditions.
- FSA-202601Several CODESYS vulnerabilities in Festo Automation Suite2026-02-26csaf · festo_psirtDE
Starting with Festo Automation Suite (FAS) version 2.8.0.138, the suite is delivered only with a connector to Codesys, rather than including Codesys directly. Prior to this version, Codesys was bundled within the FAS installation. From version 2.8.0.138 onwards, customers are required to download and install Codesys independently. This change impacts the handling of security vulnerabilities (CVEs) related to Codesys. Any Codesys-related security issues must now be addressed by the customer through their separate Codesys installation. The FAS itself includes only the connector component, which is maintained and updated within the suite. Please ensure that Codesys is kept up to date independently to mitigate any potential security risks associated with the Codesys software.
