CVE-2025-1431 is an out-of-bounds read vulnerability classified under CWE-125 that affects Autodesk AutoCAD versions 2022, 2023, 2024, and 2025. The vulnerability is triggered when AutoCAD parses a specially crafted SLDPRT file, a file format commonly used for 3D part models. Due to insufficient bounds checking during the parsing process, an attacker can cause the application to read memory outside the intended buffer boundaries. This can lead to multiple adverse outcomes: application crashes (denial of service), unauthorized disclosure of sensitive memory contents, or even arbitrary code execution within the context of the AutoCAD process. The attack vector requires the victim to open or import a malicious SLDPRT file, implying user interaction but no need for prior authentication or elevated privileges. The CVSS v3.1 base score of 7.8 reflects high severity, with metrics indicating local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Currently, there are no publicly known exploits in the wild, but the vulnerability poses a significant risk given AutoCAD's widespread use in engineering, architecture, and manufacturing industries. Autodesk has not yet published patches, so users must rely on interim mitigations and monitoring. The vulnerability is enriched by CISA, indicating recognition by US cybersecurity authorities.

The potential impact of CVE-2025-1431 is substantial for organizations relying on Autodesk AutoCAD for design and engineering workflows. Successful exploitation can lead to denial of service through application crashes, disrupting critical design processes and causing operational downtime. More critically, arbitrary code execution allows attackers to execute malicious payloads with the privileges of the AutoCAD process, potentially leading to full system compromise, lateral movement within networks, and theft or manipulation of sensitive intellectual property and design data. The confidentiality breach risks exposure of proprietary designs and client information, while integrity violations could result in corrupted or maliciously altered design files, undermining product safety and quality. Availability impacts may halt production or project timelines, causing financial and reputational damage. Given AutoCAD’s integration into industrial control environments and critical infrastructure projects, the vulnerability could also have cascading effects on national security and economic stability in affected sectors.

Until official patches are released by Autodesk, organizations should implement several targeted mitigations: 1) Restrict the sources of SLDPRT files by enforcing strict file validation and limiting file imports to trusted suppliers and internal sources only. 2) Employ sandboxing or application containment techniques to isolate AutoCAD processes, minimizing the impact of potential exploitation. 3) Monitor AutoCAD application behavior and system logs for anomalies indicative of exploitation attempts, such as unexpected crashes or unusual memory access patterns. 4) Educate users about the risks of opening untrusted SLDPRT files and enforce policies requiring verification of file provenance. 5) Use endpoint detection and response (EDR) tools to detect and block suspicious activities related to AutoCAD processes. 6) Prepare incident response plans specific to AutoCAD compromise scenarios. Once Autodesk releases patches, prioritize immediate deployment across all affected versions. Additionally, consider network segmentation to limit AutoCAD workstation exposure and apply principle of least privilege to user accounts operating AutoCAD.
