CVE-2025-66588 is an access of uninitialized pointer vulnerability (CWE-824) identified in AzeoTech DAQFactory release 20.7 (Build 2555). This vulnerability arises when the software accesses memory pointers that have not been properly initialized, leading to undefined behavior that can be exploited by attackers to execute arbitrary code. The vulnerability is classified with a CVSS 4.0 base score of 8.4 (high severity), indicating a significant risk. The attack vector is local (AV:L), meaning the attacker must have local access to the system. The attack complexity is low (AC:L), no privileges are required (PR:N), but user interaction is necessary (UI:A). The impact on confidentiality, integrity, and availability is high (VC:H, VI:H, VA:H), meaning successful exploitation could lead to full system compromise. The vulnerability does not require network access or authentication, but the need for local access and user interaction limits the attack surface primarily to insiders or users with physical or remote desktop access. DAQFactory is widely used in industrial automation and data acquisition contexts, where arbitrary code execution could disrupt critical processes. No patches or exploit code are currently publicly available, but the vulnerability is published and should be treated as a serious risk.

For European organizations, especially those in manufacturing, industrial automation, and critical infrastructure sectors using AzeoTech DAQFactory, this vulnerability poses a significant threat. Exploitation could allow attackers to execute arbitrary code, potentially leading to system compromise, data theft, operational disruption, or sabotage of industrial processes. The high impact on confidentiality, integrity, and availability means sensitive operational data could be exposed or manipulated, and control systems could be disabled or corrupted. Given the local access and user interaction requirements, insider threats or compromised user accounts are primary concerns. The disruption could affect production lines, safety systems, and data acquisition integrity, leading to financial loss, safety hazards, and regulatory non-compliance. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once details are public.

European organizations should implement strict access controls to limit local access to systems running DAQFactory, including physical security and user account management. Employ application whitelisting and endpoint detection and response (EDR) solutions to monitor for unusual behavior indicative of exploitation attempts. Educate users about the risks of interacting with untrusted content or executing unknown files to reduce the risk from required user interaction. Network segmentation should isolate DAQFactory systems from broader corporate networks to contain potential breaches. Regularly audit and monitor logs for suspicious activity related to DAQFactory processes. Prepare for rapid deployment of patches or updates from AzeoTech once available by establishing a vulnerability management process. Consider virtual patching or compensating controls such as disabling unnecessary features or services within DAQFactory to reduce attack surface. Engage with AzeoTech support channels for updates and guidance. Finally, conduct penetration testing and vulnerability assessments focused on DAQFactory environments to identify and remediate weaknesses.
