CVE-2025-1432 is a Use-After-Free (UAF) vulnerability identified in Autodesk AutoCAD versions 2022 through 2025. The vulnerability arises when AutoCAD parses maliciously crafted 3DM files, which are native design files used by AutoCAD for 3D modeling. Specifically, the flaw involves improper handling of memory objects that have been freed but are still accessed afterward, leading to undefined behavior. An attacker who crafts a specially designed 3DM file can trigger this vulnerability by convincing a user to open or import the file in AutoCAD. Exploitation can result in a range of impacts including application crashes (denial of service), unauthorized disclosure of sensitive data residing in memory, or even arbitrary code execution within the context of the AutoCAD process. This means an attacker could potentially execute malicious payloads with the same privileges as the user running AutoCAD. The vulnerability does not require prior authentication or elevated privileges, but does require user interaction in the form of opening or importing the malicious 3DM file. As of the publication date, no known exploits have been observed in the wild, and no official patches have been released by Autodesk. The vulnerability is classified under CWE-416, a common and dangerous memory corruption issue that has historically been a frequent vector for remote code execution in software handling complex file formats.

European organizations using Autodesk AutoCAD, particularly in industries such as architecture, engineering, construction, manufacturing, and design, face significant risks from this vulnerability. Successful exploitation could lead to operational disruptions due to application crashes, potentially delaying critical design workflows. More seriously, arbitrary code execution could allow attackers to compromise workstations, steal intellectual property embedded in design files, or move laterally within corporate networks. Given AutoCAD's widespread use in European industrial and infrastructure sectors, this vulnerability could be leveraged for espionage or sabotage, especially targeting firms involved in sensitive projects. The confidentiality of proprietary designs and client data is at risk, as is the integrity of design files, which could be altered maliciously. The availability of AutoCAD could also be impacted if attackers induce repeated crashes or deploy ransomware post-exploitation. The lack of known exploits currently reduces immediate risk, but the medium severity rating and the nature of the vulnerability suggest a high potential for exploitation once weaponized. Organizations relying heavily on AutoCAD should consider this a priority threat vector.

1. Implement strict file handling policies: Restrict AutoCAD users from opening 3DM files from untrusted or unknown sources. Use sandboxing or isolated environments for analyzing suspicious files. 2. Monitor and control file sharing channels: Since exploitation requires opening malicious 3DM files, enforce scanning of design files with advanced malware detection tools before distribution. 3. Employ application whitelisting and behavior monitoring: Detect anomalous AutoCAD process behavior indicative of exploitation attempts, such as unexpected memory access patterns or crashes. 4. Network segmentation: Limit AutoCAD workstations' network access to reduce lateral movement opportunities if a system is compromised. 5. Backup and integrity verification: Maintain regular backups of design files and use cryptographic hashes to detect unauthorized modifications. 6. Stay updated on vendor advisories: Although no patches are currently available, monitor Autodesk’s security bulletins closely and apply updates immediately upon release. 7. User training: Educate users on the risks of opening unsolicited or suspicious 3DM files and encourage reporting of unusual application behavior. 8. Consider deploying endpoint detection and response (EDR) solutions capable of detecting exploitation attempts related to memory corruption vulnerabilities.
