Source: CVE Database V5
Vendor/Project: Emerson
Product: ValveLink SOLO

Description

Emerson ValveLink Products store sensitive information in cleartext in memory. The sensitive memory might be saved to disk, stored in a core dump, or remain uncleared if the product crashes, or if the programmer does not properly clear the memory before freeing it.

Technical Analysis

CVE-2025-52579 is a critical vulnerability identified in Emerson's ValveLink SOLO product, categorized under CWE-316, which pertains to the storage of sensitive information in cleartext in memory. Specifically, the vulnerability arises because ValveLink SOLO does not adequately protect sensitive data in volatile memory. This data may remain in cleartext and could be inadvertently saved to disk, captured in core dumps, or left uncleared if the application crashes or if the programmer fails to explicitly clear memory before it is freed. The vulnerability has a CVSS v3.1 base score of 9.4, indicating a critical severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L) shows that the vulnerability is remotely exploitable over the network without requiring any privileges or user interaction, and it impacts confidentiality and integrity to a high degree, with a low impact on availability. The core risk is that attackers who can access system memory or memory dumps could extract sensitive information such as credentials, cryptographic keys, or configuration data, which could then be used to compromise the industrial control environment managed by ValveLink SOLO. Since Emerson ValveLink products are widely used in industrial automation and process control, this vulnerability poses a significant risk to operational technology (OT) environments, potentially enabling attackers to escalate privileges, manipulate control systems, or disrupt operations.

Potential Impact

For European organizations, especially those in critical infrastructure sectors such as oil and gas, chemical manufacturing, water treatment, and power generation, the impact of this vulnerability could be severe. Emerson ValveLink SOLO is commonly deployed in process industries across Europe, and the exposure of sensitive information could lead to unauthorized access to control systems, manipulation of industrial processes, and potential safety hazards. Confidentiality breaches could expose proprietary process data or credentials, enabling further lateral movement within OT networks. Integrity compromises could allow attackers to alter control parameters, potentially causing physical damage or operational disruptions. Although availability impact is rated low, the cascading effects of compromised control systems could indirectly affect availability of services. The lack of authentication and user interaction requirements means that attackers with network access to the affected systems can exploit this vulnerability remotely, increasing the risk profile for European organizations that have ValveLink SOLO deployed in network-accessible environments without adequate segmentation or monitoring.

Mitigation Recommendations

Mitigation should focus on immediate and practical steps beyond generic advice. First, organizations should implement strict network segmentation and access controls to limit exposure of ValveLink SOLO systems to trusted personnel and networks only. Monitoring and logging of access to these systems should be enhanced to detect anomalous activities. Since no patch or update is currently available, organizations should consider disabling or restricting features that handle sensitive data in memory if possible. Employing memory protection techniques such as encrypted memory or secure coding practices in custom integrations can reduce risk. Regularly capturing and securely handling core dumps and memory snapshots is critical; organizations should ensure these are encrypted and access-controlled. Incident response plans should be updated to include scenarios involving memory data leakage. Finally, organizations should maintain close communication with Emerson for forthcoming patches or mitigations and plan for timely deployment once available.
