  • BehobenCODESYS Runtime Toolkitcodesys_psirt

    Update the following product to version 3.5.21.0 and follow the updated documentation: * CODESYS Runtime Toolkit This update has no direct functional impact, but the improved documentation strongly discourages the CODESYS Runtime Toolkit setting 'CMPOPCUASTACK_ALLOW_SHA1_BASED_SECURITY'. If set, device manufactures need to remove the compiler #define "CMPOPCUASTACK_ALLOW_SHA1_BASED_SECURITY" from the build configuration of the CODESYS Runtime toolkit to remediate the vulnerability. This restores the default configuration and disables the affected OPC UA security policy Basic128Rsa15. Note: This prevents clients that only support the Basic128Rsa15 policy from connecting to the CODESYS UPC UA server. Device manufacturers find further information on obtaining the software update in the CODESYS Update area https://www.codesys.com/download.

  • Advisory2025-04_VDE-2025-022CODESYS Control V3 - OPC UA Server Authentication bypass2025-03-18csaf · codesys_psirtDE

    The OPC UA security policy Basic128Rsa15 is vulnerable against attacks on the private key. This can lead to loss of confidentiality or authentication bypass. The CODESYS OPC UA server is not affected in the default configuration. However, the affected policy may be enabled by a customer configuration.

  • 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.
