CVE-2025-47528 is a medium-severity vulnerability classified under CWE-862 (Missing Authorization) affecting the pewilliams Ovation Elements product up to version 1.1.2. This vulnerability arises from incorrectly configured access control security levels, allowing an attacker with limited privileges (PR:L) to exploit missing authorization checks. The CVSS 3.1 base score is 4.3, indicating a moderate risk. The attack vector is network-based (AV:N), requiring no user interaction (UI:N), and the scope remains unchanged (S:U). While confidentiality and availability are not impacted, the integrity of the system can be compromised (I:L). Essentially, an attacker with some level of authenticated access can perform unauthorized actions or access resources beyond their intended permissions due to missing or flawed authorization enforcement in the Ovation Elements platform. No known exploits are currently reported in the wild, and no patches or fixes have been published yet. The vulnerability could allow privilege escalation or unauthorized modification of data or configurations within the affected system, potentially undermining operational integrity.

For European organizations using pewilliams Ovation Elements, this vulnerability poses a risk primarily to the integrity of their operational technology or industrial control systems if Ovation Elements is used in such contexts. Unauthorized actions could lead to incorrect system states, data manipulation, or disruption of processes controlled by the software. While the vulnerability does not directly impact confidentiality or availability, integrity compromises can have cascading effects, especially in critical infrastructure sectors such as manufacturing, energy, or utilities prevalent in Europe. Attackers exploiting this flaw could alter system configurations or operational parameters, potentially causing operational inefficiencies or safety hazards. The medium severity suggests that while the threat is not immediately critical, it requires timely attention to prevent escalation or combination with other vulnerabilities. Given the network attack vector and lack of user interaction requirement, exploitation could be automated or performed remotely by insiders or external attackers with some access.

European organizations should implement the following specific mitigations: 1) Conduct a thorough access control audit on all Ovation Elements deployments to identify and rectify any misconfigurations or missing authorization checks. 2) Restrict network access to the Ovation Elements management interfaces using network segmentation, firewalls, and VPNs to limit exposure to trusted users only. 3) Enforce the principle of least privilege by reviewing and minimizing user roles and permissions within the system. 4) Monitor logs and system behavior for unusual access patterns or unauthorized actions that could indicate exploitation attempts. 5) Engage with the vendor pewilliams for updates or patches and apply them promptly once available. 6) Consider implementing compensating controls such as multi-factor authentication and anomaly detection to reduce the risk of unauthorized access. 7) Train system administrators and users on secure configuration and the importance of authorization controls to prevent accidental misconfigurations.
