EUVD-2025-16682

Comprehensive Technical Analysis of EUVD-2025-16682

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-16682, also known as CVE-2025-5086, is a deserialization of untrusted data vulnerability affecting DELMIA Apriso from Release 2020 through Release 2025. This vulnerability could lead to remote code execution (RCE), which is one of the most severe types of vulnerabilities due to its potential for complete system compromise.

Severity Evaluation:

• CVSS Base Score: 10.0 (Critical)
• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

The CVSS score of 10.0 indicates the highest level of severity. The vector string breaks down as follows:

• AV:N (Network): The vulnerability is exploitable over the network.
• AC:L (Low): The attack complexity is low, meaning it is relatively easy to exploit.
• PR:N (None): No privileges are required to exploit the vulnerability.
• UI:N (None): No user interaction is required.
• S:C (Changed): The vulnerability affects the confidentiality, integrity, and availability of the system.
• C:H (High), I:H (High), A:H (High): The impact on confidentiality, integrity, and availability is high.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Given the CVSS vector, the primary attack vector is network-based. An attacker could send maliciously crafted data over the network to exploit the deserialization vulnerability.
• Phishing and Social Engineering: Attackers could use phishing techniques to trick users into interacting with malicious content that exploits the vulnerability.

Exploitation Methods:

• Deserialization Exploits: The attacker could send serialized data that, when deserialized, executes arbitrary code on the target system.
• Payload Delivery: The attacker could embed malicious payloads within serialized data, which could be executed upon deserialization.

3. Affected Systems and Software Versions

The vulnerability affects multiple versions of DELMIA Apriso:

• Release 2020 Golden ≤ Release 2020 SP4
• Release 2021 Golden ≤ Release 2021 SP3
• Release 2022 Golden ≤ Release 2022 SP3
• Release 2023 Golden ≤ Release 2023 SP3
• Release 2024 Golden ≤ Release 2024 SP1
• Release 2025 Golden ≤ Release 2025 SP1

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Patch Management: Apply the latest patches and updates provided by Dassault Systèmes.
• Network Segmentation: Isolate affected systems from critical networks to limit the potential impact.
• Intrusion Detection Systems (IDS): Deploy IDS to monitor for suspicious network activity.

Long-Term Mitigation:

• Code Review: Conduct thorough code reviews to identify and mitigate similar vulnerabilities.
• Input Validation: Implement strict input validation to ensure that only trusted data is deserialized.
• Security Training: Educate developers and users on the risks associated with deserialization vulnerabilities.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations using DELMIA Apriso, particularly those in critical infrastructure sectors such as manufacturing, healthcare, and logistics. The potential for remote code execution could lead to data breaches, system compromises, and operational disruptions. Given the widespread use of DELMIA Apriso in Europe, this vulnerability could have far-reaching implications for the region's cybersecurity landscape.

6. Technical Details for Security Professionals

Deserialization Vulnerability:

• Root Cause: The vulnerability arises from the improper handling of untrusted data during the deserialization process.
• Exploitation: An attacker can craft serialized data that, when deserialized, executes arbitrary code. This can be achieved through various serialization formats such as JSON, XML, or binary.

Detection and Response:

• Log Analysis: Monitor logs for unusual deserialization activities or errors.
• Behavioral Analysis: Use behavioral analysis tools to detect anomalous behavior that may indicate an exploitation attempt.
• Incident Response: Develop and implement an incident response plan that includes steps for identifying, containing, and remediating the vulnerability.

Prevention:

• Secure Coding Practices: Adopt secure coding practices that include proper input validation and sanitization.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate potential risks.

Conclusion: The deserialization vulnerability in DELMIA Apriso is critical and requires immediate attention. Organizations should prioritize patching affected systems and implementing robust security measures to mitigate the risk of exploitation. The potential impact on European cybersecurity underscores the need for vigilance and proactive security management.
