Summary
FESTO Didactic CP, MPS 200, and MPS 400 Firmware

Notes

General recommendations
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 systems by using up-to-date virus detection solutions. Festo strongly recommends minimizing and protecting network access to connected devices with state-of-the-art techniques and processes. To ensure secure operation follow the recommendations in the product manuals.
Summary
Siemens SIMATIC S7-1200 and S7-1500 CPUs contained in various Festo Didactic products contain a memory protection bypass vulnerability that could allow an attacker to write arbitrary data and code to protected memory areas or read sensitive data to launch further attacks

Recommended Practices
CISA recommends users take defensive measures to minimize the exploitation risk of these vulnerabilities.
Recommended Practices
Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet.
Recommended Practices
Locate control system networks and remote devices behind firewalls and isolate them from business networks.
Recommended Practices
When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most recent version available. Also recognize VPN is only as secure as its connected devices.
Recommended Practices
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
Recommended Practices
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Recommended Practices
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Recommended Practices
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
