CVE-2025-1430 is a high-severity buffer overflow vulnerability (CWE-120) found in Autodesk AutoCAD versions 2022 through 2025. The vulnerability arises from improper handling of SLDPRT files, which are typically used for 3D part models. When AutoCAD parses a specially crafted SLDPRT file, it triggers a buffer copy operation without verifying the size of the input data, leading to memory corruption. This classic buffer overflow can be exploited by an attacker to execute arbitrary code within the context of the AutoCAD process. The vulnerability requires local access (attack vector: local), low attack complexity, no privileges, but user interaction is required (opening the malicious file). The impact on confidentiality, integrity, and availability is high, as arbitrary code execution can lead to full system compromise, data theft, or disruption of AutoCAD operations. Although no known exploits are currently reported in the wild, the presence of this vulnerability in widely used AutoCAD versions makes it a significant risk, especially in environments where AutoCAD is used to open untrusted or externally sourced SLDPRT files. The lack of an official patch at the time of reporting increases the urgency for mitigation.

For European organizations, especially those in engineering, manufacturing, architecture, and construction sectors where AutoCAD is heavily utilized, this vulnerability poses a critical risk. Successful exploitation could lead to unauthorized code execution, potentially allowing attackers to steal intellectual property, disrupt design workflows, or gain a foothold in corporate networks. Given the high confidentiality and integrity impact, sensitive design data and proprietary models could be exposed or altered. The availability impact could also be significant if attackers use this vulnerability to crash AutoCAD or deploy ransomware. Since the vulnerability requires user interaction (opening a malicious file), targeted phishing or supply chain attacks distributing compromised SLDPRT files could be effective attack vectors. The risk is amplified in collaborative environments where files are frequently exchanged across organizations and borders.

European organizations should implement the following specific mitigations: 1) Restrict AutoCAD usage to trusted users and environments; enforce strict file handling policies to avoid opening SLDPRT files from unverified sources. 2) Employ application whitelisting and sandboxing techniques to limit the impact of potential code execution within AutoCAD. 3) Monitor and control file exchange channels, including email and shared drives, to detect and block suspicious SLDPRT files. 4) Use endpoint detection and response (EDR) tools to identify anomalous behavior related to AutoCAD processes. 5) Coordinate with Autodesk for timely patch deployment once available; meanwhile, consider disabling or restricting the import of SLDPRT files if feasible. 6) Conduct user awareness training focused on the risks of opening files from untrusted sources. 7) Implement network segmentation to isolate systems running AutoCAD from critical infrastructure to limit lateral movement in case of compromise.
