CVE-2024-37038 Schneider Electric CVE debrief

Who should care

OT/ICS teams responsible for Schneider Electric Sage 1410, 1430, 1450, 2400, 3030 Magnum, and 4400 devices; administrators who manage device web interfaces; and maintenance personnel with authenticated access to these systems.

Technical summary

The advisory describes a CWE-276 incorrect default permissions issue in the device web interface. The affected products are Schneider Electric Sage 1410, 1430, 1450, 2400, 3030 Magnum, and 4400 versions C3414-500-S02K5_P8 and prior. The reported impact is unauthorized file and firmware uploads via custom web requests by an authenticated web user. The supplied CVSS vector is CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H.

Defensive priority

High priority for exposed OT environments, especially where Sage devices are reachable by operators or maintenance accounts. The remediation is straightforward and vendor-provided, but the affected surface includes firmware management paths, so delay increases risk to integrity and availability of field devices.

Recommended defensive actions

• Upgrade affected devices to firmware C3414-500-S02K5_P9 as provided by Schneider Electric.
• Inventory Sage 1410, 1430, 1450, 2400, 3030 Magnum, and 4400 devices to confirm whether any are on C3414-500-S02K5_P8 or earlier.
• Restrict access to the device web interface to only approved administrative networks and users.
• Review authentication and authorization settings for upload and firmware-management functions.
• Audit device and management logs for unexpected file or firmware upload activity.
• Follow CISA industrial control system defensive guidance and apply least-privilege access controls.
