CVE-2025-6205 is a critical missing authorization vulnerability (CWE-862) affecting Dassault Systèmes' DELMIA Apriso software, specifically versions from Release 2020 Golden through Release 2025 Golden. DELMIA Apriso is a manufacturing operations management platform widely used for production planning, execution, and monitoring in industrial environments. The vulnerability arises due to insufficient authorization checks within the application, allowing an unauthenticated attacker to gain privileged access without requiring any user interaction. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N), the flaw is remotely exploitable over the network with low attack complexity, no privileges required, and no user interaction needed. Successful exploitation could lead to full compromise of confidentiality and integrity of the affected system, enabling attackers to access sensitive manufacturing data, alter production workflows, or manipulate operational parameters. Although no known exploits are currently reported in the wild, the high severity score (9.1) and the nature of the vulnerability make it a significant risk. The lack of available patches at the time of publication further elevates the urgency for mitigation. Given the critical role of DELMIA Apriso in industrial control and manufacturing environments, this vulnerability represents a serious threat to operational continuity and intellectual property protection.

For European organizations, especially those in manufacturing, automotive, aerospace, and industrial sectors, this vulnerability poses a substantial risk. DELMIA Apriso is commonly deployed in factories and production lines to manage complex manufacturing processes; unauthorized privileged access could lead to data breaches involving proprietary designs, production schedules, and quality control data. Moreover, attackers could manipulate manufacturing workflows, causing production delays, defective products, or safety hazards. The compromise of operational technology (OT) environments could also have cascading effects on supply chains and critical infrastructure. Given Europe's strong industrial base and emphasis on Industry 4.0 initiatives, exploitation of this vulnerability could disrupt key economic sectors and erode trust in digital manufacturing solutions. Additionally, the exposure of sensitive data could lead to regulatory penalties under GDPR if personal or business-critical data is compromised.

Immediate mitigation steps include implementing network segmentation to isolate DELMIA Apriso servers from untrusted networks and restrict access to trusted administrators only. Employ strict firewall rules and VPN access controls to limit exposure. Monitor network traffic and application logs for unusual access patterns or privilege escalations. Since no patches are currently available, consider deploying application-layer firewalls or intrusion prevention systems (IPS) with custom rules to detect and block exploitation attempts targeting this vulnerability. Conduct thorough access reviews and enforce the principle of least privilege for all users interacting with DELMIA Apriso. Engage with Dassault Systèmes for timely updates and patches, and plan for rapid deployment once available. Additionally, perform regular security assessments and penetration testing focused on authorization controls within the manufacturing environment to identify and remediate similar weaknesses proactively.
