CVE-2025-6204 is a code injection vulnerability in Dassault Systèmes DELMIA Apriso. CISA added it to the Known Exploited Vulnerabilities catalogue on 28 October 2025, which means attackers have used it in real attacks. Dassault Systèmes DELMIA Apriso contains a code injection vulnerability that could allow an attacker to execute arbitrary code.
What the vulnerability means in practice
Code injection in an enterprise application is dangerous because it can turn application input handling into direct execution. In a product such as DELMIA Apriso, that can move the issue from a data-layer weakness into full application compromise, especially when the vulnerable service is reachable by trusted users, partners, or exposed interfaces.
For readers tracking the record itself, the authoritative sources for version and patch detail are the CVE Program entry and the CISA KEV catalogue, not secondary summaries.
Why this class of flaw is high impact
Code injection is high impact because it can collapse the separation between user-controlled content and server-side execution. Once an attacker can run arbitrary code, the issue is no longer just malformed input, it becomes a path to data access, process takeover, lateral movement, or persistent foothold inside the environment.
That is why exploitation of code injection is usually treated as a priority vulnerability class rather than a routine application bug. Even where the vulnerable product is not internet-facing, the blast radius can still be large if the application has access to operational data, integrations, or downstream systems.
For broader vulnerability triage, the NIST National Vulnerability Database and the NIST Cybersecurity Framework 2.0 are useful reference points for prioritising, tracking, and responding to exploitable software flaws.
How organisations assess exposure and reduce the attack surface
Exposure checks start with asset inventory, application ownership, and deployment location. Teams need to know where DELMIA Apriso is installed, which environments are reachable from the internet, and whether vendors, integrators, or remote operators can reach affected functions through trusted paths.
Vendor advisories matter because patching and mitigation details are version-specific and often change as exploitability becomes clearer. If patching is delayed, compensating controls usually focus on reducing reachability, tightening authentication paths, and limiting which accounts or systems can interact with the application.
For structured remediation prioritisation, FIRST EPSS helps estimate exploitation likelihood, while FIRST CVSS provides severity context. Where security governance is broader than a single flaw, Vulnerability Management Guide is a practical companion for asset scoping, prioritisation, and verification.
Detection, remediation, and compromise review
Detection should focus on abnormal application behaviour, unexpected child processes, unusual command execution, web-shell-like artefacts, and changes that do not align with normal Apriso administration or integration activity. After patching, organisations should still review logs, server integrity, scheduled tasks, service accounts, and outbound connections for signs that the flaw was already used.
Post-patch review matters because code injection often leaves behind more than the initial exploit. Attackers may have created new access paths, altered configuration, or captured credentials and session material while inside the application boundary. That means a “patched” state is not the same as a “clean” state.
Teams that want a benchmark for what real-world exploitation looks like can compare the incident pattern with Gladinet Hard-Coded Keys RCE Exploitation, ASP.NET machine key attacks 2025, and ToolShell SharePoint exploitation 2025, all of which show how code execution flaws can persist beyond the initial disclosure.
Risk and Threat Considerations
Code injection matters because it is one of the shortest paths from application weakness to full compromise. When the vulnerable system is an enterprise manufacturing or workflow platform, the attacker may gain access not just to the app itself but to connected business processes, credentials, and downstream operational data.
Failure mechanism: An attacker supplies crafted input that the application interprets as executable code, then uses the resulting execution context to read data, alter processes, or establish a foothold.
Impact: Successful exploitation can lead to remote code execution, operational disruption, credential exposure, lateral movement, and follow-on compromise of connected systems.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-53 Rev 5, CIS Controls v8 and OWASP ASVS set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-53 Rev 5 | SI-10 — Information Input Validation | Code injection directly concerns validating untrusted input before execution. |
| SI-2 — Flaw Remediation | Exploited code injection requires timely remediation and post-patch verification. | |
| SC-7 — Boundary Protection | Exposure depends on whether the vulnerable application is reachable across trust boundaries. | |
| Recommendation — Enforce SI-10 to validate all application input before it reaches execution paths. Use SI-2 to track, patch, and verify remediation for exploitable application flaws. Apply SC-7 to restrict network paths that can reach the vulnerable service. | ||
| CIS Controls v8 | CIS-7 — Continuous Vulnerability Management | The term centers on prioritising and remediating an actively exploited vulnerability. |
| Recommendation — Use CIS-7 to inventory, prioritise, and remediate the affected application quickly. | ||
| OWASP ASVS | V15 — Secure Coding and Architecture | Code injection is a secure-architecture and secure-coding failure mode. |
| Recommendation — Apply V15 to remove unsafe execution flows and harden server-side processing paths. | ||
Practitioner Guidance
What to watch for: Treat any confirmed code injection in a business application as a compromise-prone condition, not a simple patch ticket. The key judgement is whether the application can reach sensitive data, automation, or admin functions, because that determines the likely blast radius and the urgency of containment.
Practical response: Prioritise exposure reduction first, then verify patching with log review and integrity checks. If exploitation is suspected, rotate any credentials, tokens, or service accounts that the application could have accessed during the compromise window.
