CVE-2025-7675 is a high-severity vulnerability classified as CWE-787 (Out-of-Bounds Write) affecting Autodesk Shared Components, specifically version 2026.2. The vulnerability arises when a maliciously crafted 3DM file is parsed by Autodesk products that utilize these shared components. An out-of-bounds write occurs when the software writes data outside the boundaries of allocated memory buffers, which can lead to memory corruption. Exploiting this flaw, an attacker can cause a denial of service by crashing the application, corrupt data processed by the software, or potentially execute arbitrary code within the context of the current process. The CVSS 3.1 base score is 7.8, indicating a high severity level. The attack vector is local (AV:L), meaning the attacker must have local access to the system, but no privileges are required (PR:N). User interaction is required (UI:R), such as opening or importing the malicious 3DM file. The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Currently, no known exploits are reported in the wild, and no patches have been linked yet. Autodesk Shared Components are widely used across multiple Autodesk products, including AutoCAD, Revit, and Fusion 360, which are prevalent in design, engineering, and architecture sectors. The vulnerability's exploitation could allow attackers to compromise sensitive design data or disrupt critical workflows.

For European organizations, particularly those in architecture, engineering, construction, and manufacturing sectors relying heavily on Autodesk products, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized code execution, enabling attackers to steal intellectual property, manipulate design files, or disrupt operations by crashing critical design software. This could result in financial losses, project delays, and reputational damage. Additionally, the high impact on confidentiality and integrity is concerning for organizations handling sensitive or regulated data under GDPR, as data corruption or leakage could lead to compliance violations and penalties. The requirement for local access and user interaction somewhat limits remote exploitation but does not eliminate risk, especially in environments where files are shared or imported from external sources. The lack of available patches increases exposure until Autodesk releases updates. The absence of known exploits in the wild suggests the threat is currently theoretical but should be proactively addressed to prevent future attacks.

European organizations should implement a multi-layered mitigation approach: 1) Restrict and monitor the sources of 3DM files, especially those received from external or untrusted parties, to reduce the risk of opening malicious files. 2) Employ application whitelisting and sandboxing techniques to isolate Autodesk applications, limiting the potential damage from exploitation. 3) Enforce strict user training and awareness programs emphasizing the risks of opening unverified files and recognizing suspicious activity. 4) Maintain up-to-date backups of critical design data to enable recovery in case of data corruption or ransomware-like scenarios. 5) Monitor Autodesk's security advisories closely and apply patches promptly once available. 6) Use endpoint detection and response (EDR) solutions to identify anomalous behaviors indicative of exploitation attempts. 7) Limit local user privileges where possible to reduce the attack surface, ensuring users operate with the least privilege necessary. 8) Consider network segmentation to isolate systems running Autodesk products from broader enterprise networks, minimizing lateral movement opportunities.
