CVE-2025-9454 is an Out-of-Bounds Read vulnerability classified under CWE-125 found in Autodesk Shared Components version 2026.0. The vulnerability is triggered when a specially crafted PRT file is parsed by Autodesk products utilizing these shared components. The flaw allows an attacker to read memory outside the intended buffer boundaries, which can lead to application crashes, unauthorized disclosure of sensitive information, or even arbitrary code execution within the context of the affected process. The attack vector is local (AV:L), requiring the attacker to have access to the system and to convince a user to open or process the malicious PRT file (UI:R). No privileges are required (PR:N), and the scope is unchanged (S:U), meaning the impact is confined to the vulnerable component. The CVSS 3.1 base score is 7.8, indicating a high severity level due to the combined impact on confidentiality, integrity, and availability. Although no public exploits are known at this time, the potential for exploitation exists, especially in environments where Autodesk products are widely used for CAD and design workflows. The vulnerability underscores the risks of processing untrusted file inputs and highlights the need for robust input validation and memory safety in software handling complex file formats.

For European organizations, the impact of CVE-2025-9454 can be significant, particularly in sectors reliant on Autodesk software such as manufacturing, automotive, aerospace, architecture, and engineering. Exploitation could lead to unauthorized disclosure of intellectual property or sensitive design data, potentially causing competitive disadvantages or regulatory compliance issues under GDPR if personal data is involved. Additionally, arbitrary code execution could allow attackers to establish persistence, move laterally, or disrupt operations by crashing critical design applications, impacting productivity and project timelines. The requirement for local access and user interaction somewhat limits remote exploitation but does not eliminate risk, especially in environments with shared workstations or insufficient endpoint security controls. The vulnerability could also be leveraged as part of a multi-stage attack chain, increasing overall threat severity. Given the strategic importance of design and engineering data in European industry, the potential economic and operational consequences are considerable.

1. Monitor Autodesk’s official channels and apply security patches or updates for the Shared Components as soon as they become available. 2. Implement strict file handling policies to restrict the opening of PRT files from untrusted or unknown sources, including email attachments and downloads. 3. Employ application whitelisting and sandboxing techniques to limit the execution context of Autodesk products, reducing the impact of potential exploitation. 4. Educate users on the risks of opening unsolicited or suspicious PRT files and enforce security awareness training focused on social engineering tactics. 5. Use endpoint detection and response (EDR) solutions to monitor for anomalous behavior indicative of exploitation attempts, such as unexpected crashes or memory access violations. 6. Conduct regular security assessments and code audits for custom integrations or plugins interacting with Autodesk products to ensure they do not introduce additional vulnerabilities. 7. Network segmentation can help contain potential breaches by limiting access to critical design systems. 8. Maintain robust backup and recovery procedures to minimize downtime in case of successful exploitation causing data corruption or loss.
