3.2 VULNERABILITY OVERVIEW

3.2.1 UNCONTROLLED RESOURCE CONSUMPTION CWE-400

Uncontrolled resource consumption vulnerability exists that could cause a denial of service when an authenticated user sends a specially crafted request to a specific endpoint from within the BMS network

CVE-2025-8449 has been assigned to this vulnerability. A CVSS v3.1 base score of 4.5 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:L/UI:R/S:U/C:N/I:N/A:H).

A CVSS v4 score has also been calculated for CVE-2025-8449. A base score of 4.1 has been calculated; the CVSS vector string is (AV:A/AC:H/AT:N/PR:L/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N).

3.2.2 EXPOSURE OF SENSITIVE INFORMATION TO AN UNAUTHORIZED ACTOR CWE-200

Exposure of sensitive information to an unauthorized actor vulnerability exists that could cause unauthorized access to sensitive credential data when an attacker is able to capture local SMB traffic between a valid user within the BMS network and the vulnerable products.

CVE-2025-8448 has been assigned to this vulnerability. A CVSS v3.1 base score of 2.3 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:L/UI:R/S:U/C:L/I:N/A:N).

A CVSS v4 score has also been calculated for CVE-2025-8448. A base score of 1.0 has been calculated; the CVSS vector string is (AV:A/AC:H/AT:N/PR:L/UI:P/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N).

4. MITIGATIONS

Schneider Electric recommends users to update to the following versions of Enterprise Server, Enterprise Central, and Workstation that include a fix for the vulnerabilities:

• 7.0.2.348
• 6.0.4.10001 (CP8)
• 5.0.3.17009 (CP16)

To receive the patch:

• Step 1: Locate the appropriate version for your system on the EcoExpert Software Center
• Step 2: Follow the installation instructions provided in the accompanying readme file.
• Additionally, ensure you are following the EBO hardening guidelines

If users choose not to apply the remediation provided above, they should immediately apply the following mitigations to reduce the risk of exploit:

• Implement strong access controls to limit system access to authorized personnel.
• Use multi factor authentication if using EBO version 7.0 or later
• Use firewalls to segregate networks and protect the building management system
• Regularly monitor system activity

For more information see the associated Schneider Electric CPCERT security advisory SEVD-2025-224-04.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:

• Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
• Locate control system networks and remote devices behind firewalls and isolating them from business networks.
• 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 current version available. Also recognize VPN is only as secure as the connected devices.

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.
