Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Description

A missing authorization vulnerability affecting DELMIA Apriso from Release 2020 through Release 2025 could allow an attacker to gain privileged access to the application.

Impact

The impact of CVE-2025-6205 is substantial for organizations using DELMIA Apriso in their manufacturing and industrial operations. Unauthorized privileged access can lead to exposure of sensitive operational data, intellectual property theft, and unauthorized manipulation of production processes. This can result in production downtime, compromised product quality, financial losses, and damage to reputation. Since the vulnerability requires no authentication or user interaction, attackers can exploit it remotely and at scale, increasing the risk of widespread attacks. Industrial environments often rely on the integrity and confidentiality of their operational technology systems; thus, this vulnerability poses a direct threat to business continuity and safety. Additionally, regulatory compliance issues may arise if sensitive data is compromised. The lack of known exploits currently provides a window for mitigation, but the potential for rapid exploitation once publicized is high.

Mitigation

Organizations should immediately prepare to apply security patches from Dassault Systèmes once they become available, as patching is the definitive mitigation. Until patches are released, network segmentation should be enforced to restrict access to DELMIA Apriso instances, limiting exposure to trusted internal networks only. Implement strict access controls and monitor network traffic for unusual or unauthorized access attempts targeting the application. Employ intrusion detection and prevention systems (IDS/IPS) tuned to detect exploitation attempts related to missing authorization. Conduct thorough audits of user privileges and application logs to identify any suspicious activity. Additionally, consider deploying web application firewalls (WAFs) with custom rules to block unauthorized requests. Organizations should also engage with Dassault Systèmes support for guidance and stay informed about updates or advisories. Finally, incorporate this vulnerability into incident response plans to ensure rapid containment if exploitation occurs.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
