    The incorrect calculation of the buffer size can be avoided if the maximum supported array length of the OPC UA stack of the CODESYS Control runtime system is limited to a value of 10129639 (Stack.MaxArrayLenth=10129639) or less. This can be achieved by adding the following setting in the runtime configuration under the following path: /etc/codesys3.d/codesyscotrol.cfg

Vendor and ecosystem advisories describing this.

  • 3ADR011377AC500 V3 Multiple vulnerabilities2025-01-07csaf · abb_psirtCH

    An update is available that resolves a publicly reported vulnerability in the product versions listed as affected in the advisory. An attacker who successfully exploited these vulnerabilities could call shell functions (CVE-2023-6357), crash the PLC (CVE-2024-5000), crash the web server of the PLC (CVE-2024-8175), grant read access to files (CVE-2024-12429) or enable command execution (CVE-2024-12430). The vulnerabilities CVE-2023-6357, CVE-2024-12429 and CVE-2024-12430 require successful authentication.

  • 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.

  • VDE-2024-026CODESYS: Vulnerability can cause a DoS on CODESYS OPC UA products2024-06-04csaf · codesys_psirtDE

    The CODESYS OPC UA stack of the CODESYS Control runtime system may incorrectly calculate the required buffer size for received requests/responses. This can lead to a crash of the CODESYS runtime system during the subsequent initialization of the receive buffer with zero. Update: 10.07.2024 In the Remediation section, the release date of the update has been deleted as the update is now available.

  • VDE-2025-009WAGO: Vulnerabilities in CODESYS Control V3 - OPC UA Stack2025-02-04csaf · wago_psirtDE

    Several WAGO Firmwares are vulnerable to an incorrect calculation of the buffer size in the CODESYS OPC UA STACK. This can lead to a crash of the runtime of the affected firmware versions installed on several devices.

  • WID-SEC-W-2024-1285CODESYS: Mehrere SchwachstellenDeutsch2024-06-03csaf · cert_bundDE

    Ein Angreifer kann mehrere Schwachstellen in CODESYS ausnutzen, um einen Denial-of-Service-Zustand zu erzeugen, Dateien zu manipulieren oder vertrauliche Informationen offenzulegen.
