CVE-2025-6204: Dassault Systèmes DELMIA Apriso Code Injection Vulnerability

CVE-2025-6204 is a code injection vulnerability affecting Dassault Systèmes DELMIA Apriso. An attacker who can reach a vulnerable instance may be able to execute arbitrary code on the system. In manufacturing and operations environments where DELMIA Apriso is typically deployed, that level of access can lead to disruption of production processes, data theft, or further lateral movement, so teams should treat it as a high-priority item to inventory and remediate.

Public detail is limited to the CISA summary and the CWE classification; exact affected versions, attack vectors, and scoring must be confirmed against the vendor advisory before making final risk decisions.

How it works

The vulnerability is classified as CWE-94, improper control of generation of code (code injection). In this class of flaw, the application constructs or evaluates code or commands using untrusted input without sufficient validation or sanitization. An attacker who can supply that input may cause the application to execute attacker-controlled code in the context of the DELMIA Apriso process.

Because the CISA summary states only that the issue “could allow an attacker to execute arbitrary code,” defenders should assume that successful exploitation grants the privileges of the service account under which DELMIA Apriso runs. No further exploit mechanics, preconditions, or payload details are provided in the available facts; treat any claims of specific remote or authenticated paths as unverified until the vendor advisory is reviewed.

Am I affected? How to find it in your systems

DELMIA Apriso is manufacturing execution system (MES) software used to manage shop-floor operations, production tracking, and related industrial workflows. It commonly runs on Windows or Linux servers inside plant or enterprise networks, often integrated with other Dassault or third-party systems.

• Inventory: Query asset-management databases, CMDB records, software inventory agents, and package managers for any installation of Dassault Systèmes DELMIA Apriso. Check both production and non-production environments.
• Version and configuration review: Compare installed versions and any exposed interfaces against the vendor advisory for CVE-2025-6204. Confirm whether the product is reachable from untrusted networks or by lower-privileged users.
• Telemetry: Look for anomalous process creation, script or interpreter launches under the Apriso service account, unexpected outbound connections, or authentication failures around Apriso endpoints. Because no specific indicators of compromise are supplied in the facts, baseline normal behavior and escalate any deviation for investigation.

If the product is present and the advisory lists the installed version as affected, treat the system as vulnerable until patched or mitigated.

How to remediate

The primary action is to apply the vendor-supplied update or mitigation instructions for CVE-2025-6204. CISA’s required action is to apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for any cloud-hosted instances, or discontinue use of the product if mitigations are unavailable.

• Obtain and test the official patch or configuration change in a non-production environment first, then deploy according to your change-control process.
• After patching, verify the version string and re-scan to confirm the vulnerability is no longer present.
• For the broader code-injection class, enforce least-privilege service accounts, disable unnecessary scripting or dynamic-code features if the product allows it, and ensure input validation and output encoding are enabled wherever configurable.

Document the remediation date and retain evidence for compliance or audit purposes.

If you can't patch immediately

Until the vendor update can be applied, reduce exposure with compensating controls appropriate to a code-injection vulnerability in an MES platform:

• Network segmentation: Place DELMIA Apriso servers in a restricted zone reachable only from authorized plant-floor or operations subnets; block direct internet access and unnecessary lateral paths.
• Access restriction: Limit interactive and API access to a small set of authenticated administrative accounts; enforce multi-factor authentication where supported.
• Virtual patching / filtering: If a web application firewall or reverse proxy sits in front of the application, apply rules that reject unexpected or malformed input patterns associated with code injection; confirm any signatures against the vendor advisory.
• Feature disablement: Turn off any optional modules, scripting engines, or remote-administration interfaces that are not required for production.
• Heightened monitoring: Increase logging verbosity for the Apriso service, forward logs to a SIEM, and alert on process creation, file writes outside expected directories, or new network connections originating from the service account.

These measures lower risk but do not eliminate it; schedule the permanent patch as soon as operationally feasible.

If your data may have been exposed

Actively exploited vulnerabilities of this type can lead to unauthorized access and data exfiltration. Known ransomware use of CVE-2025-6204 is not documented in the available facts, yet any confirmed compromise should still be treated as a potential breach. Review access logs, check for unexpected data transfers, and follow your incident-response plan. As a quick additional check, individuals can run a free exposure scan of their work email addresses against known breach data sets to see whether credentials or personal information have already appeared in public dumps.
