Comprehensive Technical Analysis of EUVD-2025-34051

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-34051 is an OS Command Injection vulnerability affecting the Station Launcher App in the 3DEXPERIENCE platform. This type of vulnerability allows an attacker to execute arbitrary commands on the user's machine, potentially leading to full system compromise.

Severity Evaluation:

• CVSS Base Score: 9.0
• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H

The CVSS score of 9.0 indicates a critical vulnerability. The vector breakdown reveals the following:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): Low (L)
• User Interaction (UI): Required (R)
• Scope (S): Changed (C)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

This high score underscores the potential for significant impact on confidentiality, integrity, and availability of the affected systems.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Given the network attack vector (AV:N), an attacker could exploit this vulnerability remotely over the network.
• User Interaction: The requirement for user interaction (UI:R) suggests that the attacker might need to trick the user into performing an action, such as clicking a malicious link or opening a crafted file.

Exploitation Methods:

• Command Injection: The attacker could inject malicious commands into the Station Launcher App, which would then be executed by the underlying operating system.
• Phishing: An attacker could use phishing techniques to deliver a payload that exploits this vulnerability.

3. Affected Systems and Software Versions

The vulnerability affects the following versions of the Station Launcher App in the 3DEXPERIENCE platform:

• Release 3DEXPERIENCE R2022x Golden ≤ Release 3DEXPERIENCE R2022x.FP.CFA.2540
• Release 3DEXPERIENCE R2023x Golden ≤ Release 3DEXPERIENCE R2023x.FP.CFA.2532
• Release 3DEXPERIENCE R2024x Golden ≤ Release 3DEXPERIENCE R2024x.FP.CFA.2537
• Release 3DEXPERIENCE R2025x Golden ≤ Release 3DEXPERIENCE R2025x.FP.CFA.2532

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Patching: Apply the latest patches and updates provided by Dassault Systèmes.
• Input Validation: Implement strict input validation and sanitization to prevent command injection.
