| CVE | Weakness | CVSS v3 | Details |
|---|---|---|---|
| CVE-2025-3916 | CWE-121 Stack-based Buffer Overflow | 5.3 Medium |
A CWE-121 Stack-based Buffer Overflow vulnerability exists that could cause local attackers being able to exploit these issues to potentially execute arbitrary code while the end user opens a malicious project file (SSD file) provided by the attacker. Mitigation: Schneider Electric has identified the following specific workarounds and mitigations users can apply to reduce risk: Vendor fix: EcoStruxure Power Build Rapsody: Version v2.8.2 FR of EcoStruxure Power Build Rapsody includes a fix for this vulnerability and is available for download. ↗ Mitigation: Store the project files in a secure storage and restrict the access to only trusted users. Affected, fixed & timelineAffected:
Mitigation: When exchanging files over the network, use secure communication protocols. Mitigation: Encrypt project files when stored. Mitigation: Only open project files received from a trusted source. Mitigation: Compute a hash of the project files and regularly check the consistency of this hash to verify the integrity before usage. Vendor fix: Harden the workstation running EcoStruxure Power Build Rapsody Mitigation: Schneider Electric strongly recommends the following industry cybersecurity best practices: Mitigation: Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network. Mitigation: Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks. Mitigation: Place all controllers in locked cabinets and never leave them in the "Program" mode. Mitigation: Never connect programming software to any network other than the network for the devices that it is intended. Mitigation: 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. Mitigation: Never allow laptops that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation. Mitigation: Minimize network exposure for all control system devices and systems, and ensure that they are not accessible from the Internet. Mitigation: 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. Mitigation: For more information, see Schneider Electric security notification SEVD-2025-133-03. |
