CVE-2025-50109 Emerson CVE debrief

CVE-2025-50109 is a high-severity information exposure issue in Emerson ValveLink products. According to CISA’s advisory, affected versions of ValveLink SOLO, DTM, PRM, and SNAP-ON before 14.0 may store sensitive information in cleartext in a resource that could be accessible across a control sphere boundary. Emerson recommends upgrading to ValveLink 14.0 or later.

Who should care

OT/ICS operators using Emerson ValveLink SOLO, DTM, PRM, or SNAP-ON versions earlier than 14.0; plant engineers; system administrators; and asset owners responsible for Windows-based engineering or maintenance workstations that interact with control systems.

Technical summary

CISA’s CSAF advisory for ICSA-25-189-01 describes a cleartext storage weakness: sensitive information may be written to a resource that another control sphere can access. The affected products are Emerson ValveLink SOLO, DTM, PRM, and SNAP-ON with versions earlier than ValveLink 14.0. The published CVSS 3.1 vector is AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N, reflecting a local-access exposure with high confidentiality and integrity impact and no availability impact.

Defensive priority

High. This is a published high-severity exposure in OT-related software, and the vendor-provided mitigation is straightforward: upgrade to a fixed release.

Recommended defensive actions

  • Upgrade Emerson ValveLink SOLO, DTM, PRM, and SNAP-ON to ValveLink 14.0 or later using Emerson’s software download portal.
  • Identify any systems running ValveLink versions earlier than 14.0 and prioritize them for patching or removal from service until updated.
  • Review workstation and file-access controls so sensitive configuration or credential material is not left in cleartext on shared or reachable resources.
  • Limit access to engineering and maintenance workstations to authorized users only and apply least-privilege controls where feasible.
  • Monitor Emerson security notifications and validate the updated software package before deployment in production environments.
