Who should care

Organizations running Samsung HVAC DMS in industrial, facilities, or OT-adjacent environments should review this immediately, especially if the system is reachable from other networks or the Internet. System integrators and operators responsible for maintaining these deployments should also verify version status and mitigation steps.

Technical summary

The advisory describes a deserialization-of-untrusted-data weakness in Samsung DMS (Data Management Server). CISA lists these affected ranges: Samsung HVAC DMS >=2.0.0 and <2.3.13.0; >=2.5.0.17 and <2.6.14.0; and >=2.7.0.15 and <2.9.3.5. The provided CVSS vector is CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H, corresponding to a HIGH severity score of 8.0. The remediation guidance states the product is not intended to be connected to the Internet and should remain on a separate dedicated network.

Defensive priority

High. The advisory indicates code-execution impact on affected Samsung HVAC DMS versions, and the vendor/CISA guidance calls for both updating and network isolation.

Recommended defensive actions

Confirm whether any Samsung HVAC DMS instance is running an affected version range: 2.0.0-<2.3.13.0, 2.5.0.17-<2.6.14.0, or 2.7.0.15-<2.9.3.5.
Contact a Samsung call center or installer to obtain and apply the recommended software update.
Disconnect affected systems from the Internet and keep them on a separate dedicated network, per the advisory and product manual statement.
Review network exposure and reduce access paths to the DMS until updates are applied.
Document remediation status for OT/facilities asset inventories and track the advisory ICSA-25-210-02 for any follow-up revisions.
