CVE-2025-10889 is a classic buffer overflow vulnerability (CWE-120) identified in Autodesk Shared Components version 2026.0. The vulnerability occurs due to a lack of proper bounds checking when parsing CATPART files, which are proprietary 3D CAD part files used by Autodesk products. A specially crafted CATPART file can trigger memory corruption, allowing an attacker to overwrite memory buffers and potentially execute arbitrary code within the context of the affected process. The vulnerability is exploitable when a user opens or processes the malicious file, requiring user interaction but no prior authentication or elevated privileges. The CVSS 3.1 base score of 7.8 reflects high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required, but user interaction needed. While no exploits have been reported in the wild yet, the vulnerability poses a significant risk due to the widespread use of Autodesk software in design and manufacturing sectors. The lack of available patches at the time of disclosure necessitates immediate attention to mitigate potential exploitation. Attackers could leverage this flaw to execute code remotely if combined with social engineering or phishing to deliver the malicious file. The vulnerability highlights the critical need for secure input validation and memory management in software handling complex file formats.

For European organizations, especially those in manufacturing, engineering, and design sectors relying on Autodesk products, this vulnerability can lead to severe consequences. Successful exploitation could result in arbitrary code execution, enabling attackers to compromise system confidentiality by accessing sensitive design data, alter integrity by modifying CAD files or software behavior, and disrupt availability by crashing applications or systems. This could lead to intellectual property theft, sabotage of design processes, and operational downtime. Given the reliance on Autodesk software in automotive, aerospace, and industrial manufacturing hubs across Europe, the threat could affect critical supply chains and innovation pipelines. Additionally, exploitation could serve as a foothold for lateral movement within corporate networks, escalating the risk of broader compromise. The requirement for user interaction limits remote exploitation but does not eliminate risk, as attackers may use phishing or social engineering to deliver malicious CATPART files. The absence of known exploits in the wild currently reduces immediate risk but does not preclude future attacks once exploit code becomes available.

1. Monitor Autodesk’s official channels for patches or updates addressing CVE-2025-10889 and apply them promptly once released. 2. Implement strict file handling policies to restrict opening CATPART files from untrusted or unknown sources, including email attachments and external downloads. 3. Employ application whitelisting and sandboxing techniques to limit the execution context of Autodesk applications, reducing the impact of potential exploitation. 4. Educate users about the risks of opening unsolicited or suspicious CAD files, emphasizing caution with email attachments and downloads. 5. Utilize endpoint detection and response (EDR) solutions capable of detecting anomalous behavior indicative of exploitation attempts, such as unexpected memory access patterns or process injections. 6. Consider network segmentation to isolate design and engineering workstations from critical infrastructure to limit lateral movement. 7. Conduct regular backups of critical design files and systems to enable recovery in case of compromise. 8. Review and harden system configurations, including disabling unnecessary features or plugins in Autodesk products that may increase attack surface.
