What are all the CVE numbers and severity scores for the Emerson ValveLink vulnerabilities?

The vulnerabilities include: CVE-2025-52579 (CVSS 9.3) for cleartext storage of sensitive information in memory, CVE-2025-50109 (CVSS 8.5) for cleartext storage of sensitive information in memory, CVE-2025-46358 (CVSS 8.5) for protection mechanism failure, CVE-2025-48496 (CVSS 5.9) for uncontrolled search path element, and CVE-2025-53471 (CVSS 5.9) for improper input validation.

Which Emerson ValveLink products are affected by these vulnerabilities?

The vulnerabilities impact all versions of the following ValveLink products prior to version 14.0: ValveLink SOLO, ValveLink DTM, ValveLink PRM, and ValveLink SNAP-ON. All versions of these products prior to ValveLink 14.0 are vulnerable.

What can attackers do if they exploit these Emerson ValveLink vulnerabilities?

Attackers could potentially read sensitive information stored in cleartext memory, tamper with system parameters, execute unauthorized code on critical manufacturing systems, access sensitive data from memory dumps or crash files, bypass protection mechanisms, and potentially gain control over industrial valve control systems.

Are these Emerson ValveLink vulnerabilities being actively exploited?

No known public exploitation targeting these vulnerabilities has been reported to CISA at this time. However, given the critical nature of some vulnerabilities and their potential impact on industrial systems, organizations should prioritize patching regardless of current exploitation status.

What should organizations do immediately about these ValveLink vulnerabilities?

Organizations using affected ValveLink products should immediately update to ValveLink version 14.0 or later. They should also review their industrial control systems for any ValveLink installations, prioritize critical manufacturing systems for updates, and monitor systems for any signs of unauthorized access or tampering.

What makes the cleartext storage vulnerabilities in ValveLink particularly dangerous?

The cleartext storage vulnerabilities (CVE-2025-52579 and CVE-2025-50109) are particularly dangerous because sensitive information stored in memory can persist in memory dumps, core dumps, or disk files, making it accessible to attackers even after the system appears to be secure. This could expose critical system credentials, configuration data, or operational parameters.

What is Emerson ValveLink and why are these vulnerabilities concerning?

Emerson ValveLink is an industrial control system product line used for valve management and control in critical manufacturing and industrial processes. These vulnerabilities are concerning because they affect industrial control systems that are essential for safe and reliable operation of manufacturing facilities, and compromise could lead to production disruption or safety issues.

How can organizations obtain the ValveLink security updates?

Organizations can download the ValveLink 14.0 software upgrade directly from the Emerson website. Detailed information about the security updates and installation procedures is available in the associated Emerson security notification. Organizations should contact Emerson support if they need assistance with the upgrade process.

What is a protection mechanism failure vulnerability?

CVE-2025-46358 is classified as a protection mechanism failure with a CVSS score of 8.5. This type of vulnerability occurs when security controls or protective measures in the software fail to work as intended, potentially allowing attackers to bypass security restrictions and gain unauthorized access to system functions or data.

What risks do the input validation and search path vulnerabilities pose?

CVE-2025-53471 (improper input validation) and CVE-2025-48496 (uncontrolled search path element) both have CVSS scores of 5.9. These vulnerabilities could allow attackers to inject malicious input or manipulate file paths to execute unauthorized code, access restricted files, or cause system instability in the ValveLink environment.

How urgent is it to patch these Emerson ValveLink vulnerabilities?

Patching is highly urgent, especially for the critical vulnerability CVE-2025-52579 with a CVSS score of 9.3. While no active exploitation has been reported, these vulnerabilities affect critical industrial control systems, and any compromise could have significant operational and safety implications. Organizations should prioritize immediate updates to ValveLink 14.0.

What industries should be most concerned about these ValveLink vulnerabilities?

Industries that rely heavily on industrial valve control systems should be most concerned, including oil and gas, chemical processing, power generation, water treatment, pharmaceuticals, food and beverage manufacturing, and other process industries where ValveLink products are commonly used for critical valve management and control operations.

Are there any workarounds for these ValveLink vulnerabilities if immediate patching isn't possible?

While updating to ValveLink 14.0 is the recommended solution, temporary measures may include network segmentation to isolate ValveLink systems, implementing additional access controls, monitoring for suspicious activity, and restricting physical and remote access to ValveLink installations. However, these are temporary measures and patching should be prioritized.

What should security teams monitor for regarding these ValveLink vulnerabilities?

Security teams should monitor for unauthorized access to ValveLink systems, unusual network traffic to/from ValveLink installations, attempts to access memory dumps or core files, unexpected system crashes or restarts, unauthorized changes to valve configurations or parameters, and any signs of lateral movement from ValveLink systems to other industrial control systems.

How do these vulnerabilities affect industrial cybersecurity?

These vulnerabilities highlight ongoing cybersecurity challenges in industrial control systems, where legacy systems may have been designed with limited security considerations. The discovery of multiple high-severity vulnerabilities in widely-used valve control systems demonstrates the importance of regular security assessments and updates in industrial environments.

What additional security measures should organizations implement after patching ValveLink?

After patching, organizations should implement network segmentation for industrial control systems, deploy monitoring solutions for anomaly detection, establish regular security assessment schedules, implement strong access controls and authentication for industrial systems, maintain updated asset inventories, and develop incident response procedures specific to industrial control system compromises.

What does this CISA advisory mean for regulatory compliance?

CISA advisories often influence regulatory compliance requirements, especially for critical infrastructure sectors. Organizations may need to demonstrate that they have addressed these vulnerabilities as part of their cybersecurity compliance obligations. Failure to patch known vulnerabilities in industrial control systems could result in regulatory violations or increased scrutiny from oversight bodies.

Advisory

CISA reports multiple vulnerabilities in Emerson ValveLink products, at least one critical

Q: Has Emerson released patches for these ValveLink vulnerabilities?

Yes, Emerson has released patches in ValveLink version 14.0. Organizations using affected ValveLink products should immediately update to ValveLink 14.0 or later versions. The software upgrade can be downloaded directly from the Emerson website, and detailed information is available in the associated Emerson security notification.

published: July 9, 2025

Take action: If you have Emerson ValveLink products (SOLO, DTM, PRM, or SNAP-ON), make sure it's isolated from the internet and accessible only from trusted networks. Then check your version and plan an upgrade to ValveLink 14.0. The issues may not be immediately exploitable, but given enough time it will be exploited. Plan a regular patch.
