Vulnerability from csaf_se - Published: 2023-04-11 09:46 - Updated: 2024-08-13 00:00Summary
Modicon PLCs (Programmable Logic Controllers) and PACs (Programmable Automation Controllers)
Notes
General Security Recommendations
We strongly recommend the following industry cybersecurity best practices.
https://www.se.com/us/en/download/document/7EN52-0390/
* Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network.
* Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks.
* Place all controllers in locked cabinets and never leave them in the “Program” mode.
* Never connect programming software to any network other than the network intended for that device.
* Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks.
* Never allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation.
* Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet.
* When remote access is required, use secure methods, such as Virtual Private Networks (VPNs). 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.
For more information refer to the Schneider Electric Recommended Cybersecurity Best Practices document.
Note regarding vulnerability details
The severity of vulnerabilities was calculated using the CVSS Base metrics in version 3.1 (CVSS v3.1) without incorporating the Temporal and Environmental metrics. Schneider Electric recommends that customers score the CVSS Environmental metrics, which are specific to end-user organizations, and consider factors such as the presence of mitigations in that environment. Environmental metrics may refine the relative severity posed by the vulnerabilities described in this document within a customer’s environment
For More Information
This document provides an overview of the identified vulnerability or vulnerabilities and actions required to mitigate. For more details and assistance on how to protect your installation, contact your local Schneider Electric representative or Schneider Electric Industrial Cybersecurity Services: https://www.se.com/ww/en/work/solutions/cybersecurity/. These organizations will be fully aware of this situation and can support you through the process.

Overview
Schneider Electric is aware of multiple vulnerabilities in its Modicon PLCs (Programmable Logic Controllers) and PACs (Programmable Automation Controllers).
Modicon PLCs (Programmable Logic Controllers) and PACs (Programmable Automation Controllers) control and monitor industrial operations in a sustainable, flexible, efficient, and protected way.
Failure to apply the remediations and mitigations provided below may risk a denial of service of the controller, which could result in disrupted operations.
Note
Regarding vulnerability details: The severity of vulnerabilities was calculated using the CVSS Base metrics in version 3.1 (CVSS v3.1) without incorporating the Temporal and Environmental metrics. Schneider Electric recommends that customers score the CVSS Environmental metrics, which are specific to end-user organizations, and consider factors such as the presence of mitigations in that environment. Environmental metrics may refine the relative severity posed by the vulnerabilities described in this document within a customer’s environment.
