What the vulnerability is
CVE-2025-6205 is a missing authorization vulnerability (CWE-862) identified in Dassault Systèmes DELMIA Apriso. This flaw could allow an attacker to bypass intended access controls and gain privileged access to the application.
Exposure and applicability
This vulnerability affects organizations utilizing DELMIA Apriso as their Manufacturing Execution System (MES). Because MES platforms sit at the intersection of IT and OT—managing production schedules, work orders, and quality data—unauthorized privileged access to this layer could potentially allow an actor to modify operational parameters or view sensitive manufacturing data.
Asset owners should determine if their specific deployment of DELMIA Apriso is affected by reviewing vendor documentation. The vulnerability’s presence in the CISA Known Exploited Vulnerabilities catalog indicates a heightened risk profile for those using this software in industrial environments.
Remediation priorities
Based on our analysis, OT security leaders and plant managers should prioritize the following actions to reduce exposure:
- Vendor Mitigation Deployment: The primary priority is to apply mitigations as specified by Dassault Systèmes. If the MES is hosted via cloud services, organizations should align their response with BOD 22-01 guidance.
- Access Review: While awaiting or applying patches, administrators should review current privileged account activity for any anomalies that might indicate unauthorized access.
- Network Segmentation: Ensure the MES application is isolated from general business networks and the public internet to limit the potential paths an attacker could use to reach the vulnerable interface.
- Decommissioning Evaluation: In scenarios where vendor mitigations are unavailable or cannot be applied due to operational constraints, organizations should evaluate whether to discontinue use of the affected product version to eliminate the risk.
How to validate remediation
Validation should be conducted through a controlled change management process. We recommend the following approach:
- Version and Patch Verification: Confirm that the applied update or mitigation matches the vendor’s specified requirements for CVE-2025-6205.
- Authorization Testing: In a non-production environment, authorized security personnel should verify that users without privileged credentials cannot access restricted administrative functions previously exposed by the missing authorization flaw.
Avoid performing active vulnerability scanning or intrusive testing on production MES instances, as this could disrupt manufacturing operations.
Limits and open questions
The source does not specify which versions of DELMIA Apriso are affected, nor does it detail the exact technical mechanism used to bypass authorization. Additionally, while the vulnerability is listed in the CISA catalog, it remains unknown if it has been utilized specifically by ransomware campaigns. Users should refer directly to the Dassault Systèmes Trust Center for specific version applicability and detailed patching instructions.
