As part of a security strategy, Festo recommends the following general defense measures to reduce the risk of exploits: - Use controllers and devices only in a protected environment to minimize network exposure and ensure that they are not accessible from outside - Use firewalls to protect and separate the control system network from other networks - Use VPN (Virtual Private Networks) tunnels if remote access is required Activate and apply user management and password features - Use encrypted communication links - Limit the access to both development and control system by physical means, operating system features, etc. - Protect both development and control system by using up to date virus detecting solutions Festo strongly recommends to minimize and protect network access to connected devices with state of the art techniques and processes. For a secure operation follow the recommendations in the product manuals.

- Mitigationendress_hauser_psirt
The CDC 90 device is not designed for network connectivity by default. Since it is not connected to a network, the vulnerabilities cannot be exploited. However, if the customer chooses to connect the device to a network, the default firewall settings should be maintained, as this will mitigate the security vulnerabilities. For the CC 100 and PFC 200 devices, ensure that the default firewall settings remain intact and that both PLC Runtime and PLC WebVisu are disabled. This configuration effectively mitigates the identified security vulnerabilities.

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.
