CVE-2025-6205: 3ds Delmia Apriso Privilege Escalation

CVE-2025-6205 Overview

A missing authorization vulnerability has been identified in DELMIA Apriso, a manufacturing execution system (MES) developed by Dassault Systèmes (3DS). This vulnerability affects DELMIA Apriso from Release 2020 through Release 2025 and could allow an unauthenticated attacker to gain privileged access to the application through network-based exploitation.

Critical Impact
This vulnerability is actively exploited in the wild and has been added to CISA's Known Exploited Vulnerabilities (KEV) catalog. Organizations using affected DELMIA Apriso versions should prioritize immediate remediation.

Technical Details for CVE-2025-6205

Vulnerability Analysis

This vulnerability is classified under CWE-862 (Missing Authorization), indicating that the affected DELMIA Apriso application fails to perform proper authorization checks when processing certain requests. The missing authorization control allows attackers to bypass intended access restrictions and gain elevated privileges within the application.

DELMIA Apriso is widely deployed in manufacturing environments for production operations management, quality management, and logistics operations. The critical nature of this vulnerability stems from its potential to grant attackers administrative or privileged access to manufacturing execution systems, which could lead to significant operational disruption or data compromise in industrial environments.

Root Cause

The root cause of CVE-2025-6205 is the absence of proper authorization validation in one or more application endpoints or functions within DELMIA Apriso. When authorization checks are missing, the application fails to verify whether an authenticated or unauthenticated user has the appropriate permissions to access specific resources or perform sensitive operations. This allows threat actors to directly access functionality that should be restricted to privileged users.

Attack Vector

The vulnerability is exploitable over the network without requiring authentication or user interaction. An attacker with network access to a vulnerable DELMIA Apriso instance can craft requests that bypass the missing authorization controls, effectively elevating their privileges within the application. This could enable unauthorized access to sensitive manufacturing data, configuration changes, or administrative functions.

The attack does not require prior authentication (PR:N) and can be executed without any user interaction (UI:N), making it particularly dangerous in environments where DELMIA Apriso instances are accessible from broader network segments.

Detection Methods for CVE-2025-6205

Indicators of Compromise

Unexpected privileged operations or administrative actions performed by unauthenticated or low-privileged users in DELMIA Apriso audit logs
Anomalous access patterns to restricted DELMIA Apriso endpoints or resources
Unauthorized configuration changes within the DELMIA Apriso application
Network traffic to DELMIA Apriso servers from unexpected sources or containing unusual request patterns

Detection Strategies

Review DELMIA Apriso application logs for access to administrative or privileged functionality without corresponding authentication events
Implement network-level monitoring to detect unauthorized access attempts to DELMIA Apriso servers
Deploy web application firewall (WAF) rules to detect and block exploitation attempts targeting missing authorization patterns
Utilize endpoint detection and response (EDR) solutions to monitor for post-exploitation activity on systems hosting DELMIA Apriso

Monitoring Recommendations

Enable comprehensive audit logging within DELMIA Apriso to capture all access attempts and privilege escalation events
Monitor for CISA KEV catalog updates and threat intelligence feeds related to CVE-2025-6205 exploitation
Implement alerting on failed and successful authentication events followed by privileged operations
Review network segmentation to ensure DELMIA Apriso servers are not unnecessarily exposed to untrusted network segments

How to Mitigate CVE-2025-6205

Immediate Actions Required

Identify all DELMIA Apriso installations within your environment and determine which versions are deployed
Consult the 3DS Security Advisory for CVE-2025-6205 for vendor-provided remediation guidance
Restrict network access to DELMIA Apriso servers to only authorized users and systems until patches can be applied
Review the CISA Known Exploited Vulnerabilities entry for additional remediation deadlines and guidance

Patch Information

Dassault Systèmes has released security guidance for this vulnerability. Organizations should consult the official 3DS Security Advisory for specific patch versions and upgrade instructions. Given the active exploitation status and CISA KEV listing, patching should be treated as a high-priority activity.

Workarounds

Implement network-level access controls to restrict access to DELMIA Apriso servers to trusted IP ranges and users only
Deploy a web application firewall (WAF) in front of DELMIA Apriso to filter potentially malicious requests
If feasible, temporarily disable or restrict access to non-essential DELMIA Apriso functionality until patches are applied
Enhance monitoring and logging to detect any exploitation attempts while awaiting full remediation

bash

# Example: Restrict network access to DELMIA Apriso using host-based firewall (Linux iptables)
# Allow access only from trusted management network
iptables -A INPUT -p tcp --dport 443 -s 10.0.10.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
