CVE-2025-6631 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 PRT file is parsed by certain 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. Exploitation of this vulnerability can result in a range of impacts including application crashes, data corruption, or potentially arbitrary code execution within the context of the affected process. The vulnerability requires local access (AV:L), low attack complexity (AC:L), no privileges (PR:N), but user interaction (UI:R) to trigger the exploit. The scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). This means an attacker who convinces a user to open a malicious PRT file could execute code, potentially taking control of the affected Autodesk application or causing denial of service. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is specific to the 2026.2 version of Autodesk Shared Components, which are used by multiple Autodesk products, particularly those handling PRT files, commonly associated with CAD and 3D modeling workflows.

For European organizations, especially those in engineering, manufacturing, architecture, and design sectors that rely heavily on Autodesk products, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized code execution, allowing attackers to compromise sensitive intellectual property, disrupt design workflows, or cause data loss through corruption or application crashes. Given the high confidentiality and integrity impact, attackers could steal or manipulate proprietary designs or blueprints, potentially affecting competitive advantage and compliance with data protection regulations such as GDPR. The requirement for user interaction means phishing or social engineering could be used to deliver malicious PRT files, increasing the risk in environments where users exchange design files frequently. Disruption of critical design and manufacturing processes could also have downstream effects on supply chains and project timelines across European industries.

Organizations should implement targeted mitigations beyond generic advice: 1) Restrict and monitor the receipt and opening of PRT files, especially from untrusted or external sources. 2) Employ application whitelisting and sandboxing techniques for Autodesk products to contain potential exploitation. 3) Educate users on the risks of opening unsolicited or suspicious PRT files and implement strict email filtering to block potentially malicious attachments. 4) Maintain strict version control and inventory of Autodesk software to identify and prioritize patching once updates become available. 5) Use endpoint detection and response (EDR) tools to monitor for anomalous behavior indicative of exploitation attempts. 6) Coordinate with Autodesk support channels for timely updates and patches, and apply them promptly upon release. 7) Consider network segmentation to isolate systems running vulnerable Autodesk components from critical infrastructure.
