3. TECHNICAL DETAILS

3.1 AFFECTED PRODUCTS

The following versions of EcoStruxure™ are affected by the vulnerability:

• EcoStruxure™ Process Expert: Versions 2020R2, 2021 & 2023 (prior to v4.8.0.5715)
• EcoStruxure™ Process Expert for AVEVA System Platform: Versions 2020R2, 2021 & 2023

3.2 VULNERABILITY OVERVIEW

3.2.1 IMPROPER PRIVILEGE MANAGEMENT CWE-269

This vulnerability arises from improper privilege management in two services: one that manages audit trail data and another that serves client requests. An attacker with standard privileges could modify the executable path of these Windows services, leading to significant security breaches. To exploit this vulnerability, the affected services must be restarted, which adds a layer of complexity to the attack.

The vulnerability has been assigned CVE-2025-0327, with a CVSS v3.1 base score of 7.8 and a CVSS v4 score of 8.5. These scores indicate a high level of risk, necessitating immediate attention from users and administrators.

3.3 BACKGROUND

• CRITICAL INFRASTRUCTURE SECTORS: Commercial Facilities, Critical Manufacturing, Energy, Water and Wastewater Systems
• COUNTRIES/AREAS DEPLOYED: Worldwide
• COMPANY HEADQUARTERS LOCATION: France

3.4 RESEARCHER

The vulnerability was reported by Charit Misra from DNV Cyber, highlighting the collaborative efforts in cybersecurity to identify and address potential threats.

4. MITIGATIONS

In response to the identified vulnerability, Schneider Electric has outlined specific remediations and mitigations for users:

• Upgrade to Version v4.8.0.5715: This version of EcoStruxure™ Process Expert 2023 includes a fix for the vulnerability and is available for download.
• Uninstall Previous Versions: Users should uninstall Version 2023 (v4.8.0.5115) before installing the updated version (v4.8.0.5715). The version string can be found on the engineering server console.

Schneider Electric emphasizes the importance of using appropriate patching methodologies and recommends backing up systems before applying updates. Users are encouraged to evaluate the impact of these patches in a test environment before deployment.

If users opt not to apply the recommended updates, they should implement the following mitigations:

• Restrict Execute Permissions: For EcoStruxure™ Process Expert Versions 2020R2, 2021 & 2023 (prior to v4.8.0.5715), allow execute permission for the service control Windows utility only to admin users. Utilize McAfee Application and Change Control software to restrict execution to whitelisted applications.
• Admin User Restrictions: For EcoStruxure™ Process Expert for AVEVA System Platform, restrict execute permissions of the sc.exe Windows utility to admin users until a remediation plan is established.

Schneider Electric also recommends adhering to industry cybersecurity best practices:

• Network Isolation: Place control and safety system networks behind firewalls and isolate them from business networks.
• Physical Security: Implement physical controls to prevent unauthorized access to industrial control systems.
• Secure Configuration: Ensure all controllers are secured in locked cabinets and not left in “Program” mode.
• Data Exchange Scanning: Scan all mobile data exchange methods before use in terminals connected to control networks.
• Minimize Network Exposure: Limit network exposure for control system devices and ensure they are not accessible from the Internet.
• Secure Remote Access: Use secure methods like VPNs for remote access, while being aware of their vulnerabilities.

For further guidance, users can refer to Schneider Electric’s Recommended Cybersecurity Best Practices document.

CISA (Cybersecurity and Infrastructure Security Agency) also advises organizations to perform impact analysis and risk assessments before deploying defensive measures. They provide resources for control systems security recommended practices on their website, including strategies for proactive defense of ICS assets.

Organizations should report any suspected malicious activity to CISA for tracking and correlation against other incidents. Additionally, CISA recommends measures to protect against social engineering attacks, such as:

• Avoiding Unsolicited Emails: Do not click links or open attachments in unsolicited messages.
• Recognizing Email Scams: Refer to CISA resources for guidance on avoiding email scams.
• Understanding Social Engineering: Familiarize yourself with tactics used in social engineering attacks.

As of now, there have been no known public exploitations targeting this specific vulnerability, and it is not exploitable remotely, which provides a temporary buffer for organizations to implement necessary mitigations.
