CVE-2025-9455 is an out-of-bounds read vulnerability classified under CWE-125, affecting Autodesk Shared Components version 2026.0. The vulnerability is triggered when the software parses specially crafted CATPRODUCT files, which are typically used in CAD environments to represent product assemblies. An attacker can craft such a file to cause the software to read memory beyond the intended buffer boundaries. This can lead to several adverse effects: application crashes (denial of service), unauthorized disclosure of sensitive information from memory, or even arbitrary code execution within the context of the affected process. The vulnerability requires local access and user interaction (opening or importing the malicious file) but does not require elevated privileges, making it accessible to a wide range of threat actors who can trick users into opening malicious files. The CVSS 3.1 base score is 7.8, indicating high severity, with a vector showing low attack complexity, no privileges required, but user interaction necessary. Although no exploits are currently known in the wild, the potential for impactful exploitation exists, especially in environments where Autodesk products are widely used for design and manufacturing workflows. The lack of available patches at the time of publication necessitates immediate risk mitigation through other controls. This vulnerability affects confidentiality, integrity, and availability, as it can lead to data leakage, unauthorized code execution, and service disruption.

For European organizations, the impact of CVE-2025-9455 is significant, particularly for those in sectors relying heavily on Autodesk products, such as automotive, aerospace, industrial manufacturing, and engineering design. Successful exploitation can lead to leakage of intellectual property and sensitive design data, which could have severe economic and competitive consequences. Arbitrary code execution could allow attackers to establish persistence, move laterally within networks, or deploy ransomware and other malware, disrupting critical business operations. The requirement for user interaction means phishing or social engineering could be vectors for exploitation, increasing risk in environments with less stringent user awareness. Additionally, the vulnerability could undermine trust in design data integrity, affecting product quality and compliance with regulatory standards. The potential for denial of service through crashes could interrupt design workflows, causing operational delays. Given the interconnected nature of supply chains in Europe, a compromise in one organization could cascade, affecting partners and customers.

1. Monitor Autodesk’s official channels closely for patches addressing CVE-2025-9455 and apply them promptly once released. 2. Until patches are available, restrict the opening of CATPRODUCT files to trusted sources only, employing strict file validation and sandboxing where possible. 3. Implement application whitelisting and endpoint protection solutions capable of detecting anomalous behavior related to file parsing and memory access violations. 4. Educate users about the risks of opening unsolicited or unexpected CAD files, emphasizing caution with email attachments and downloads. 5. Employ network segmentation to isolate systems running Autodesk products from broader enterprise networks, limiting lateral movement if exploitation occurs. 6. Utilize advanced threat detection tools that can identify exploitation attempts based on memory corruption or unusual process activity. 7. Regularly back up critical design data and verify the integrity of backups to enable recovery in case of compromise. 8. Review and harden user privilege assignments to minimize the impact of potential code execution within user contexts. 9. Consider deploying application-level sandboxing or virtualization to contain the effects of malicious file processing.
