3.2.4 SERVER-SIDE REQUEST FORGERY CWE-918

Schneider Electric EcoStruxure Power Monitoring Expert is vulnerable to pre-authentication server-side request forgery. This vulnerability may allow a remote attacker to access internal services directly when the attacker sends a specially crafted document to a vulnerable endpoint.

CVE-2025-54924 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.5 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).

A CVSS v4 score has also been calculated for CVE-2025-54924. A base score of 8.7 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N).

3.2.5 SERVER-SIDE REQUEST FORGERY CWE-918

Schneider Electric EcoStruxure Power Monitoring Expert is vulnerable to pre-authentication server-side request forgery. This vulnerability may allow a remote attacker to access internal services directly when the attacker configures the application to access a malicious url.

CVE-2025-54925 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.5 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).

A CVSS v4 score has also been calculated for CVE-2025-54925. A base score of 8.7 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N).

4. MITIGATIONS

Schneider Electric will include fixes for these vulnerabilities as part of the next release of the product PME 2024 R3, planned for November 11, 2025. Until then, users are recommended to:

• Ensure PME is running in an isolated network.
• Deploy and configure the Windows firewall to limit access to appropriate network segments.
• Enforce complex password policies.
• Review Server Access Permissions
• Conduct an audit of all Windows-authenticated users who currently have access to PME. Repeat this audit of your system periodically.
• Identify all accounts with access rights, especially those with elevated privileges or remote access.
• Limit access to essential users only.
• Revoke access for any user accounts that are not critical for system functionality or daily operations.
• Apply the principle of least privilege to ensure users have only the access necessary for their role(s).

Additionally, users should ensure the deployment of PME has followed the cybersecurity hardening guidelines provided with the product.

For more information, see the associated Schneider Electric CPCERT security advisory, SEVD-2025-224-02 EcoStruxure Power Monitoring Expert (PME) - PDF Version, CSAF Version.

Schneider Electric recommends the following general security practices:

• Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network.
• Install physical controls to ensure that 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.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. 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.

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/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

CISA also recommends users take the following measures to protect themselves from social engineering attacks:

• Do not click web links or open attachments in unsolicited email messages.
• Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
• Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.

No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
