CVE-2025-13957 Schneider Electric CVE debrief

Who should care

Administrators and security teams responsible for Schneider Electric EcoStruxure IT Data Center Expert deployments, especially environments still running versions 9.0 or earlier, or any instance where SOCKS Proxy has been enabled. Asset owners using the product in operational or industrial environments should prioritize this advisory.

Technical summary

The advisory describes a hard-coded credentials weakness. If SOCKS Proxy is enabled and the attacker has administrator credentials plus PostgreSQL database credentials, the issue may lead to information disclosure and remote code execution. The source notes that SOCKS Proxy is disabled by default. The advisory’s stated severity is CVSS v4.0 7.5 High, while the supplied record also contains a CVSS 3.1 vector and a separate cvssScore value of 7.2; the advisory text should be treated as the primary severity statement.

Defensive priority

High. Update to EcoStruxure IT Data Center Expert v9.1 as soon as practical. If immediate upgrading is not possible, verify that SOCKS Proxy remains disabled and harden the deployment using Schneider Electric’s Security Handbook and CISA industrial control system defensive guidance.

Recommended defensive actions

• Upgrade Schneider Electric EcoStruxure IT Data Center Expert to v9.1, which the vendor identifies as containing the fix.
• Confirm SOCKS Proxy is disabled on all affected deployments and keep it disabled unless there is a documented operational need.
• Review and harden the DCE instance using Schneider Electric’s EcoStruxure IT Data Center Expert Security Handbook.
• Validate administrator and PostgreSQL credential hygiene, including rotation where policy or exposure warrants it.
• Use CISA industrial control system recommended practices to reduce attack surface and improve monitoring.
• Track vendor and CISA advisory updates for any revised remediation guidance or affected-version clarification.
