CVE-2025-1431 is a high-severity vulnerability identified in Autodesk AutoCAD versions 2022 through 2025. The vulnerability arises from an out-of-bounds read (CWE-125) triggered when AutoCAD parses a specially crafted SLDPRT file, a file format commonly used for 3D part models. This flaw allows a malicious actor to manipulate the parsing process to read memory beyond the intended buffer boundaries. The consequences of this vulnerability include causing the AutoCAD process to crash (denial of service), unauthorized reading of sensitive data from memory, or potentially executing arbitrary code within the context of the AutoCAD process. The CVSS v3.1 base score is 7.8, indicating a high severity, with the attack vector being local (AV:L), requiring low attack complexity (AC:L), no privileges (PR:N), but user interaction (UI:R) is necessary. The scope remains unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Although no known exploits are currently reported in the wild, the vulnerability's nature suggests that exploitation could lead to significant compromise of systems running vulnerable AutoCAD versions, especially in environments where untrusted SLDPRT files are opened. The lack of available patches at the time of reporting increases the urgency for mitigation. This vulnerability is particularly critical because AutoCAD is widely used in engineering, architecture, and manufacturing sectors, where sensitive intellectual property and design data are handled.

For European organizations, the impact of CVE-2025-1431 can be substantial. AutoCAD is extensively used across Europe in industries such as automotive, aerospace, construction, and manufacturing, all of which rely on the confidentiality and integrity of design files. Exploitation could lead to unauthorized disclosure of proprietary designs, intellectual property theft, or disruption of critical design workflows through crashes or code execution. This could result in financial losses, reputational damage, and potential regulatory consequences under GDPR if sensitive personal data is indirectly exposed. Additionally, compromised systems could serve as footholds for further lateral movement within corporate networks, escalating the risk of broader cyberattacks. The requirement for user interaction means phishing or social engineering campaigns could be used to deliver malicious SLDPRT files, increasing the attack surface. Given the high impact on confidentiality, integrity, and availability, organizations involved in critical infrastructure or strategic industries in Europe must prioritize addressing this vulnerability.

To mitigate CVE-2025-1431 effectively, European organizations should: 1) Immediately restrict the opening of SLDPRT files from untrusted or unknown sources, implementing strict file validation and sandboxing where possible. 2) Employ application whitelisting and endpoint protection solutions that can detect and block anomalous behavior related to AutoCAD processes. 3) Educate users, especially engineers and designers, about the risks of opening unsolicited or suspicious SLDPRT files, emphasizing safe handling practices. 4) Monitor AutoCAD application logs and system behavior for signs of crashes or unusual activity that could indicate exploitation attempts. 5) Coordinate with Autodesk for timely patch deployment once available; meanwhile, consider deploying virtual desktop infrastructure (VDI) or isolated environments for handling untrusted files to contain potential exploitation. 6) Implement network segmentation to limit the impact of a compromised AutoCAD workstation on broader corporate networks. 7) Regularly back up critical design data and verify backup integrity to ensure recovery capability in case of disruption.
