CVE-2025-66587 is a vulnerability identified in AzeoTech's DAQFactory, a software product used for data acquisition and industrial automation. The CVSS 4.0 vector indicates that exploitation requires local access (AV:L), with high attack complexity (AC:H), no privileges (PR:N), but user interaction is necessary (UI:P). The vulnerability severely impacts confidentiality, integrity, and availability (all rated high), indicating that successful exploitation could lead to significant unauthorized data disclosure, data manipulation, or service disruption. The vulnerability does not require authentication (AT:N) and does not affect system components remotely (SC:N), limiting the attack surface to local users who can interact with the system. No known exploits are currently in the wild, and no patches have been released, suggesting that the vulnerability is newly disclosed and may not yet be actively exploited. The lack of detailed technical information or CWE classification limits precise understanding of the vulnerability's nature, but the high impact ratings imply a critical flaw in how DAQFactory handles user inputs or local operations. Given DAQFactory's role in industrial control and data acquisition, exploitation could disrupt critical monitoring and control processes.

For European organizations, particularly those involved in industrial automation, manufacturing, and critical infrastructure monitoring, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive operational data, manipulation of control parameters, or denial of service conditions affecting production lines or safety systems. The requirement for local access and user interaction reduces the likelihood of remote mass exploitation but increases risk from insider threats or compromised endpoints within secure environments. Confidentiality breaches could expose proprietary process data or personal information, while integrity and availability impacts could cause operational downtime, safety incidents, or financial losses. Given the critical nature of industrial control systems in Europe’s manufacturing and energy sectors, the vulnerability could have cascading effects on supply chains and service continuity.

European organizations using DAQFactory should implement strict local access controls, ensuring only authorized personnel can interact with systems running the software. Employ endpoint security solutions to detect and prevent malicious activities originating from local users. Conduct targeted user awareness training emphasizing the risks of interacting with untrusted content or executing unknown operations within DAQFactory. Monitor system logs and network traffic for anomalies indicative of exploitation attempts. Until a patch is available, consider isolating DAQFactory systems from general user workstations and restrict physical and logical access. Engage with AzeoTech for updates and apply patches promptly once released. Additionally, implement application whitelisting and privilege restrictions to limit the ability of malicious actors to exploit the vulnerability via user interaction.
