CVE-2025-9452 is a classic buffer overflow vulnerability (CWE-120) identified in Autodesk Shared Components version 2026.0. The flaw occurs due to a lack of proper bounds checking when parsing SLDPRT files, which are proprietary 3D part files used in Autodesk CAD products. A specially crafted SLDPRT file can trigger memory corruption by overflowing a buffer during the file parsing process. This memory corruption can be exploited by an attacker to execute arbitrary code within the context of the current process, potentially leading to full compromise of the affected application. The vulnerability has a CVSS v3.1 score of 7.8, indicating high severity, with an attack vector classified as local (AV:L), meaning the attacker must have local access to the system. No privileges are required (PR:N), but user interaction is necessary (UI:R), such as opening or importing the malicious file. The vulnerability affects Autodesk Shared Components 2026.0, a core library used by multiple Autodesk products, which increases the attack surface. Although no known exploits have been reported in the wild, the potential for arbitrary code execution makes this a critical concern for organizations relying on Autodesk software for design and engineering tasks. No patches or fixes have been published yet, so users remain vulnerable. The vulnerability was reserved in August 2025 and published in December 2025, indicating a recent discovery.

For European organizations, especially those in manufacturing, engineering, architecture, and product design sectors that heavily rely on Autodesk software, this vulnerability poses a significant risk. Exploitation could lead to unauthorized code execution, resulting in data theft, intellectual property compromise, or disruption of critical design workflows. Given the local attack vector and requirement for user interaction, the threat is more likely to arise from targeted attacks or insider threats where malicious files are introduced into the environment. The high confidentiality, integrity, and availability impacts could affect sensitive design files and project timelines, potentially causing financial losses and reputational damage. Additionally, compromised systems could serve as footholds for further lateral movement within corporate networks. The lack of patches increases exposure duration, emphasizing the need for proactive mitigation.

1. Restrict the sources of SLDPRT files by enforcing strict file acceptance policies and validating file origins before opening or importing them. 2. Implement application whitelisting and sandboxing for Autodesk products to limit the impact of potential exploitation. 3. Educate users on the risks of opening files from untrusted or unknown sources to reduce the likelihood of user interaction with malicious files. 4. Monitor system and application logs for unusual behavior indicative of exploitation attempts, such as crashes or unexpected process activity. 5. Employ endpoint detection and response (EDR) solutions capable of detecting anomalous memory corruption or code injection activities. 6. Coordinate with Autodesk for timely patch deployment once available and apply updates promptly. 7. Consider network segmentation to isolate design workstations and limit lateral movement if compromise occurs. 8. Use file integrity monitoring on critical design files and shared components to detect unauthorized changes.
