CVE-2025-6205 is a critical security vulnerability classified under CWE-862 (Missing Authorization) affecting Dassault Systèmes DELMIA Apriso software from Release 2020 Golden through Release 2025 Golden. DELMIA Apriso is a manufacturing operations management platform widely used for coordinating production, supply chain, and quality processes. The vulnerability arises because the application fails to properly enforce authorization checks, allowing an attacker to gain privileged access remotely over the network without requiring any authentication or user interaction. This means an attacker can potentially access sensitive operational data, manipulate workflows, or escalate privileges within the application environment. The CVSS 3.1 base score of 9.1 indicates a critical severity with the attack vector being network-based (AV:N), no privileges required (PR:N), no user interaction (UI:N), and high impact on confidentiality and integrity (C:H/I:H), but no impact on availability (A:N). Although no exploits have been reported in the wild yet, the ease of exploitation and the critical nature of the flaw make it a significant threat. The vulnerability affects multiple major releases spanning six years, indicating a long exposure window. Dassault Systèmes has not yet published patches, so organizations must prepare to deploy updates promptly once available. The missing authorization flaw could be exploited by attackers to compromise manufacturing operations, steal intellectual property, or disrupt supply chain integrity.

For European organizations, especially those in manufacturing, automotive, aerospace, and industrial sectors relying on DELMIA Apriso, this vulnerability poses a severe risk. Unauthorized privileged access could lead to theft of sensitive production data, intellectual property, and operational secrets. Attackers could manipulate manufacturing workflows, causing quality issues or production delays, indirectly affecting product integrity and supply chain reliability. The confidentiality and integrity impacts could also lead to regulatory non-compliance under GDPR if personal or sensitive data is exposed or altered. The lack of availability impact reduces the risk of direct denial-of-service but does not mitigate the critical threat of unauthorized access. Given the strategic importance of manufacturing in Europe, exploitation could have economic and reputational consequences. The absence of known exploits currently provides a window for proactive defense, but the vulnerability’s criticality demands urgent attention.

1. Monitor Dassault Systèmes advisories closely and apply security patches immediately upon release to remediate the missing authorization flaw. 2. Until patches are available, implement strict network segmentation to isolate DELMIA Apriso servers from untrusted networks and limit access to trusted administrators only. 3. Employ robust access control mechanisms such as VPNs, multi-factor authentication, and IP whitelisting to restrict remote access. 4. Conduct thorough audits of user permissions and application logs to detect any unauthorized access attempts or anomalies. 5. Use application-layer firewalls or intrusion detection/prevention systems (IDS/IPS) to monitor and block suspicious traffic targeting DELMIA Apriso endpoints. 6. Educate operational technology and IT teams about the vulnerability to ensure rapid incident response readiness. 7. Review and enhance internal authorization policies and configurations within DELMIA Apriso to minimize privilege escalation risks. 8. Consider deploying honeypots or decoy systems to detect potential exploitation attempts early.
