Emerson ValveLink Products Multiple Critical Vulnerabilities
Free public brief. The indicators, the detections with Splunk SPL already written (plus Elastic and KQL where they apply), and a Slack alert the next time this touches a vendor you run are in the app — free account, no card.
Emerson ValveLink products contain cleartext credential storage and other flaws allowing remote code execution; upgrade to version 14.0.
Emerson has patched five vulnerabilities across its ValveLink SOLO, DTM, PRM, and SNAP-ON product lines affecting all versions prior to 14.0. The most critical is CVE-2025-52579, a cleartext storage of sensitive information flaw in memory (CVSS 9.3) reachable over the network with low attack complexity. The vulnerability allows attackers with system access to read credentials, tamper with valve parameters, and execute unauthorized code. Additional flaws include improper protection mechanisms (CVE-2025-46358), local cleartext credential storage (CVE-2025-50109), uncontrolled search path issues (CVE-2025-48496), and input validation failures (CVE-2025-53471). ValveLink products are used in critical manufacturing infrastructure globally. CISA reports no current public exploitation, but the remotely-exploitable nature of the primary flaw and the sensitivity of industrial control applications warrant immediate patching. Emerson recommends upgrading to ValveLink 14.0 or later.

Detection guidance
Emerson ValveLink Application Spawning Script Interpreter or Shell
ValveLink SOLO/DTM/PRM/SNAP-ON processes spawning PowerShell, cmd or other script hosts, which may indicate code execution through the ValveLink vulnerabilities. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.
title: Emerson ValveLink Application Spawning Script Interpreter or Shell
id: 3338a7c3-006b-5547-8f50-19aee4254ada
status: experimental
description: Detects ValveLink (SOLO, DTM, PRM, SNAP-ON) processes spawning PowerShell,
cmd or other script hosts. The advisory notes that the ValveLink flaws allow unauthorized
code execution, and these engineering applications do not normally launch interpreters.
This is a hypothesis-driven detection, because the advisory describes no observed
exploitation and gives no process names, so the match relies on the product name
appearing in the parent image path.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries its extracted indicators, its detections (Splunk SPL already written, plus Elastic and Microsoft KQL where they apply), the actors and CVEs it names as live profiles, and the vendor research on the same campaign — the primary source the news paraphrased, cited and read directly.
It sits in a corpus of 13,854 reports from 146 sources, 616 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Name the vendors you run and Slack hears about the reports that touch them — about forty a week that are yours, not the four hundred that are not.
