CVE-2025-69970 is an insecure default configuration vulnerability identified in FUXA version 1.2.7, an industrial automation and control software. The root cause is that the 'secureEnabled' flag in the server/settings.default.js configuration file is commented out by default, which disables authentication mechanisms upon initial installation. This misconfiguration allows unauthenticated remote attackers to access sensitive API endpoints without any credentials. Attackers can exploit this to modify projects, potentially altering industrial control workflows, and gain unauthorized control over connected industrial equipment. Since authentication is disabled by default, exploitation requires no user interaction or prior authentication, making the attack surface broad and the vulnerability highly exploitable. The vulnerability affects installations immediately after deployment if default settings are not changed. Although no CVSS score has been assigned, the vulnerability's impact is severe due to the direct control over industrial equipment, risking operational disruption, safety hazards, and data integrity breaches. No patches or exploits in the wild are currently reported, but the risk remains significant given the nature of the affected systems. The vulnerability highlights the critical importance of secure default configurations in industrial control software to prevent unauthorized access and control.

For European organizations, especially those in manufacturing, energy, and critical infrastructure sectors using FUXA for industrial automation, this vulnerability poses a significant risk. Unauthorized access to control systems can lead to manipulation of industrial processes, causing operational downtime, safety incidents, and potential physical damage to equipment. Confidentiality of sensitive project data and operational parameters can be compromised, leading to intellectual property theft or sabotage. The availability and integrity of industrial systems are at risk, potentially disrupting supply chains and critical services. Given Europe's strong industrial base, particularly in countries like Germany, France, Italy, and the UK, the impact could be widespread, affecting both large enterprises and smaller industrial operators. The lack of authentication also increases the likelihood of automated exploitation attempts if attackers discover vulnerable installations exposed to the internet or accessible within corporate networks.

Organizations should immediately verify and modify the FUXA configuration to ensure the 'secureEnabled' flag is explicitly set to true before deploying or using the software in production environments. Conduct a thorough review of all default configuration files to confirm that authentication and other security controls are enabled. Implement network segmentation to isolate industrial control systems from general IT networks and restrict access to trusted personnel only. Employ strong access control policies and monitor API endpoints for unauthorized access attempts. Regularly audit and update software configurations and maintain an inventory of all FUXA instances to ensure compliance with security best practices. If possible, deploy intrusion detection systems tailored for industrial control environments to detect anomalous activities. Engage with the vendor or community for updates or patches addressing this vulnerability once available. Finally, conduct security awareness training for operational technology staff to recognize and respond to potential exploitation attempts.
