CVE-2025-1429 is a heap-based buffer overflow vulnerability classified under CWE-122, affecting Autodesk AutoCAD versions 2022, 2023, 2024, and 2025. The vulnerability is triggered when AutoCAD parses a maliciously crafted MODEL file, which can overflow heap memory buffers. This overflow can lead to several adverse outcomes: application crashes (denial of service), unauthorized reading of sensitive memory contents, or execution of arbitrary code within the AutoCAD process context. The vulnerability requires user interaction, specifically opening or importing the malicious MODEL file, but does not require any prior authentication or elevated privileges. The CVSS v3.1 base score is 7.8, indicating a high severity level, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), and user interaction required (UI:R). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). No patches or fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. The vulnerability is particularly critical because AutoCAD is widely used in engineering, architecture, and manufacturing industries, where compromise could lead to intellectual property theft, operational disruption, or further network compromise.

The potential impact of CVE-2025-1429 is significant for organizations relying on Autodesk AutoCAD for design and engineering workflows. Exploitation can lead to arbitrary code execution, enabling attackers to gain control over the AutoCAD process and potentially pivot to broader network compromise. Confidentiality is at risk due to possible unauthorized memory reads, which could expose sensitive design files or proprietary information. Integrity and availability are also threatened, as attackers can cause application crashes or manipulate design data. This could disrupt critical operations in sectors such as manufacturing, construction, and infrastructure development. The requirement for user interaction (opening a malicious MODEL file) means social engineering or phishing campaigns could be used to deliver the exploit. The lack of current patches increases exposure, and organizations without strict file validation or sandboxing controls are particularly vulnerable. The widespread use of AutoCAD globally amplifies the risk of targeted attacks against high-value engineering and architectural firms.

To mitigate CVE-2025-1429, organizations should implement the following specific measures: 1) Restrict AutoCAD file imports to trusted sources only and enforce strict file validation policies to detect malformed MODEL files. 2) Employ application whitelisting and sandboxing techniques to isolate AutoCAD processes and limit the impact of potential exploitation. 3) Educate users on the risks of opening unsolicited or unexpected MODEL files, emphasizing cautious handling of email attachments and downloads. 4) Monitor AutoCAD process behavior for anomalies such as unexpected crashes or memory access violations that may indicate exploitation attempts. 5) Coordinate with Autodesk for timely patch deployment once fixes become available, and subscribe to vendor security advisories. 6) Implement network segmentation to limit lateral movement if an AutoCAD host is compromised. 7) Use endpoint detection and response (EDR) tools to detect exploitation attempts based on known heap overflow behaviors. These targeted actions go beyond generic advice and address the specific attack vector and exploitation method of this vulnerability.
