Privileged Access Risk in Dassault Systèmes DELMIA Apriso (CVE-2025-6205)

Historical catalog analysis: CISA added this entry on October 28, 2025. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.

What the vulnerability is

CVE-2025-6205 is a missing authorization vulnerability (CWE-862) identified in Dassault Systèmes DELMIA Apriso. The flaw allows an attacker to bypass intended authorization checks, potentially granting them privileged access to the application.

Exposure and applicability

This vulnerability affects organizations utilizing DELMIA Apriso. Because the flaw involves a failure to properly authorize requests, any asset running the affected software is susceptible to unauthorized privilege escalation if the attacker can reach the application interface. Infrastructure owners should identify all instances of this product across their environment, including those deployed in cloud configurations.

Remediation priorities

Based on our analysis, vulnerability management teams should prioritize the following actions:

1. Apply Vendor Mitigations: The primary corrective action is to implement the specific mitigations provided by Dassault Systèmes. This is the most direct method to address the missing authorization logic.
2. Cloud Service Review: For organizations utilizing this software via cloud services, we recommend reviewing and applying guidance consistent with BOD 22-01 to ensure that service provider configurations do not exacerbate the exposure.
3. Decommissioning Assessment: In scenarios where vendor mitigations are unavailable or cannot be applied due to environment constraints, the risk should be managed by discontinuing use of the product to eliminate the attack surface.

How to validate remediation

Verification must go beyond a simple version check, as a software update does not inherently prove that authorization controls are functioning as intended in a specific deployment.

To verify that exposure has been reduced, defenders should perform authorized testing of the application’s authorization boundaries. This involves attempting to access privileged functions using an account with low or no privileges to confirm that the system now correctly denies these requests. Evidence of remediation is established when the application consistently enforces authorization checks and rejects unauthorized attempts to gain privileged access.

Limits and open questions

While the vulnerability is documented, it remains unknown whether this flaw has been utilized by ransomware campaigns. Additionally, while CISA has established a remediation deadline for federal agencies, this date does not automatically apply to private sector organizations, though it serves as a benchmark for urgency. Residual risk remains if compensating controls are used instead of a direct patch, as these may only limit the paths to exploitation rather than fixing the underlying authorization failure.
