CVE-2025-9458 is a classic buffer overflow vulnerability (CWE-120) identified in Autodesk Shared Components version 2026.3. The flaw occurs due to insufficient validation of input size when parsing PRT files, a file format used by Autodesk for 3D CAD models. A maliciously crafted PRT file can overflow a buffer, causing memory corruption that enables an attacker to execute arbitrary code within the context of the running Autodesk process. The vulnerability requires the victim to open or process the malicious PRT file, implying user interaction is necessary. No privileges or authentication are required, but the attack vector is local (AV:L), meaning the attacker must have access to the system or trick the user into opening the file. The CVSS 3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability. While no exploits have been reported in the wild, the vulnerability poses a significant risk due to the potential for remote code execution via social engineering or spear phishing with malicious PRT attachments. Autodesk has not yet released a patch, so organizations must rely on interim mitigations. This vulnerability is particularly concerning for industries relying heavily on Autodesk software for design and manufacturing workflows.

For European organizations, the impact of CVE-2025-9458 is substantial, especially in sectors such as automotive, aerospace, industrial manufacturing, and engineering services where Autodesk products are widely used. Successful exploitation can lead to full compromise of affected systems, enabling attackers to steal intellectual property, disrupt design processes, or deploy further malware. The confidentiality of proprietary CAD designs and trade secrets is at risk, as is the integrity of design files, potentially causing downstream production errors. Availability may also be affected if the exploited process crashes or is manipulated. Given the reliance on Autodesk software in critical infrastructure and manufacturing supply chains across Europe, this vulnerability could have cascading effects on operational continuity and competitive advantage. The requirement for user interaction limits mass exploitation but does not eliminate targeted attacks, particularly spear phishing campaigns aimed at design engineers and CAD operators.

1. Monitor Autodesk’s official channels for patches addressing CVE-2025-9458 and apply updates immediately upon release. 2. Until patches are available, restrict access to PRT files from untrusted sources and implement strict file handling policies. 3. Employ application whitelisting to prevent unauthorized execution of malicious files. 4. Use endpoint protection solutions that include behavior-based detection to identify exploitation attempts. 5. Enable and enforce Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) on systems running Autodesk software to mitigate exploitation success. 6. Conduct user awareness training focused on the risks of opening unsolicited or unexpected PRT files. 7. Implement network segmentation to isolate systems running Autodesk products from general user networks, reducing exposure. 8. Regularly audit and monitor logs for unusual activity related to Autodesk processes. 9. Consider sandboxing or opening PRT files in controlled environments when possible. 10. Develop incident response plans specific to potential exploitation scenarios involving design software.
