CVE-2025-11862 identifies a critical authorization vulnerability in Rockwell Automation's Verve Asset Manager, a tool used for managing industrial assets. The vulnerability arises from improper authorization checks (classified under CWE-863) within the product's API. Specifically, users assigned read-only permissions can exploit this flaw to perform unauthorized operations including reading, updating, and deleting user accounts. This indicates a failure in enforcing least privilege principles and access control mechanisms at the API level. The affected versions range from 1.33 to 1.41.3, covering a broad deployment base. The CVSS 4.0 score of 8.4 reflects a high-severity rating, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no user interaction (UI:N), and no privileges required beyond read-only (PR:L). The vulnerability impacts confidentiality to a limited extent but severely compromises integrity and availability by allowing unauthorized modification and deletion of user data. Although no exploits are currently known in the wild, the potential for misuse in industrial environments is significant given the critical role of asset management in operational technology (OT) environments. The vulnerability was publicly disclosed on November 11, 2025, with no patches currently available, underscoring the urgency for risk mitigation. The flaw's exploitation could disrupt asset tracking, user management, and potentially lead to broader operational disruptions if attackers manipulate user credentials or permissions. This vulnerability is particularly concerning for organizations relying on Rockwell Automation's solutions for critical infrastructure and industrial control systems.

For European organizations, the impact of CVE-2025-11862 is substantial, especially those in manufacturing, energy, utilities, and critical infrastructure sectors where Rockwell Automation products are prevalent. Unauthorized modification or deletion of user accounts can lead to loss of control over asset management systems, potentially causing operational downtime, data integrity issues, and increased risk of further compromise. The ability to update and delete users without proper authorization can facilitate insider threats or external attackers pivoting within networks, undermining trust in identity and access management. This could result in regulatory non-compliance, financial losses, and reputational damage. Given the interconnected nature of industrial control systems, exploitation could cascade into broader operational technology disruptions, affecting supply chains and critical services. The vulnerability's network accessibility and lack of required user interaction increase the likelihood of exploitation, raising the urgency for European organizations to assess exposure and implement mitigations promptly.

1. Monitor Rockwell Automation's official channels for patches addressing CVE-2025-11862 and apply them immediately upon release. 2. Until patches are available, restrict API access to Verve Asset Manager by implementing strict network segmentation, limiting access to trusted hosts and networks only. 3. Enforce multi-factor authentication (MFA) and robust identity and access management policies to minimize the risk of unauthorized access. 4. Conduct thorough audits of user permissions within Verve Asset Manager to ensure no excessive privileges are granted, especially for read-only users. 5. Deploy application-layer firewalls or API gateways that can enforce granular access controls and detect anomalous API usage patterns. 6. Implement continuous monitoring and logging of API calls to detect unauthorized read, update, or delete operations promptly. 7. Educate operational technology and security teams about this vulnerability to enhance incident response readiness. 8. Consider isolating Verve Asset Manager environments from broader corporate networks to reduce attack surface exposure. 9. Review and update incident response plans to include scenarios involving asset management system compromise.
