Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.\nFor more information refer to the Schneider Electric Recommended Cybersecurity Best Practices document. \n",

These vulnerabilities pose several risks, primary among these is the possibility of arbitrary code execution and loss of confidentiality and integrity of the project file.\nWith all products affected an attack would first involve an authenticated user gaining access to the engineering station; or an unauthenticated user gaining access to a project file or to the process control network.\nOur findings demonstrate that while the discovered vulnerabilities affect Schneider Electric offers, it is possible to mitigate the potential impacts by following standard guidance, specific instructions; and in some cases, the fixes provided by Schneider Electric to remove the vulnerabilities.\nPlease ensure that if you are an EcoStruxure\u2122 Control Expert user to apply the latest security updates provided below. For users of any of the mentioned products see the mitigation section in this security notice for further information on how to help protect your system from possible attack.\nSchneider Electric encourages all industrial companies to ensure they have implemented cybersecurity best practices across their operations and supply chains to reduce cyber risks. Where appropriate this includes locating industrial systems and remotely accessible devices behind firewalls; installing physical controls to prevent unauthorized access; preventing mission-critical systems and devices from being accessed from outside networks; systematically applying security patches.\nMarch 2023 Update: Remediation for the Modicon M580 CPU is available for download (page 8).\nWe will update this document when the fixes are available. To ensure you are informed of the upcoming security notifications updates, subscribe to Schneider Electric\u2019s security notification service here: https://www.se.com/en/work/support/cybersecurity/security-notifications.jsp\nNote: A Proof-of-Concept script code that could potentially exploit some of these vulnerabilities has been discovered. Remediation and mitigation actions documented in this notification document will reduce the risk of exploit.",

The second step is to update the firmware of the Modicon Controllers referenced.\nImportant Note:\n\u2022 The fix is provided through the additional feature \u201cfile encryption\u201d, for further information on the feature and how to set it up please refers to the chapter \u201cfile encryption\u201d of the help file available in the EcoStruxure\u2122 Control Expert v15.0 SP1.\n\u2022 This feature is proposed by default when creating a new project.\n\u2022 This feature is also available, after selecting \u201cproject\u201d in structural view, in the \u201cEdit/ Properties/ Project \u0026 Controller Protection\u201d menu.\n\u2022 For new projects: Customers are recommended to apply this feature to all new projects.\n\u2022 For existing projects: Customers are recommended to apply this feature to the existing projects coming from trusted source. For sta project files, as a reminder, project modification can be done in connected mode to prevent desynchronization and keep the controller in RUN state.\n\u2022 It is possible to set a security level specific to the Derived Function Blocks (DFB) in addition to the file encryption feature. Please refer to the chapter \"How to protect a DFB type\" in the EcoStruxure\u2122 Control Expert help file for further information.\n\u2022 Customers are recommended to share project files only when configured with the encryption feature described above.\nIf customers choose not to apply the remediation provided above, they should immediately apply the following mitigations to reduce the risk of exploit. These mitigations also reduce the risk of exploit for CVE-2021-22779 on all versions of EcoStruxure\u2122 Control Expert, including V15.1:\n\u2022 Store the project files in a secure storage and restrict the access to only trusted users\n\u2022 When exchanging files over the network, use secure communication protocols\n\u2022 Encrypt project files when stored\n\u2022 Only open project files received from trusted source\n\u2022 Compute a hash of the project files and regularly check the consistency of this hash to verify the integrity before usage\n\u2022 Harden the workstation running EcoStruxure\u2122 Control Expert or Unity Pro\nCustomers using Unity Pro should strongly consider migrating to EcoStruxure\u2122 Control Expert.
