CVE-2025-1429 is a high-severity heap-based buffer overflow vulnerability (CWE-122) affecting multiple recent versions of Autodesk AutoCAD (2022 through 2025). The vulnerability arises when AutoCAD parses a maliciously crafted MODEL file, which can trigger a heap overflow condition. This memory corruption flaw enables an attacker to cause a denial of service (application crash), read sensitive memory contents, or execute arbitrary code within the context of the AutoCAD process. Exploitation requires the victim to open or otherwise process the malicious MODEL file, which implies user interaction is necessary. The CVSS v3.1 base score of 7.8 reflects a high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required, but user interaction is needed. No known public exploits have been reported yet, but the vulnerability is enriched by CISA, indicating government-level awareness. The lack of available patches at the time of disclosure highlights the urgency for affected organizations to implement mitigations and monitor for updates. Given AutoCAD's widespread use in engineering, architecture, and construction industries, exploitation could lead to significant operational disruption and data compromise.

For European organizations, the impact of CVE-2025-1429 could be substantial, especially for those in sectors heavily reliant on AutoCAD for design and engineering workflows, such as manufacturing, construction, automotive, aerospace, and infrastructure development. Successful exploitation could lead to unauthorized disclosure of intellectual property embedded in design files, disruption of critical design processes through application crashes, and potential system compromise if arbitrary code execution is achieved. This could result in project delays, financial losses, and reputational damage. Additionally, given the integration of AutoCAD files in collaborative environments, a compromised system could serve as a pivot point for broader network intrusion. The requirement for user interaction (opening a malicious MODEL file) means that social engineering or phishing campaigns targeting employees are plausible attack vectors. European organizations must be vigilant due to stringent data protection regulations (e.g., GDPR), where data breaches involving sensitive design data could lead to regulatory penalties.

1. Implement strict file handling policies: Restrict the acceptance and opening of MODEL files from untrusted or unknown sources. 2. Employ network segmentation and least privilege principles to limit AutoCAD's access to sensitive network resources and data. 3. Use application whitelisting and endpoint protection solutions capable of detecting anomalous behavior related to AutoCAD processes. 4. Educate users on the risks of opening unsolicited or suspicious MODEL files, emphasizing phishing awareness. 5. Monitor vendor communications closely for Autodesk patches or updates addressing CVE-2025-1429 and apply them promptly once available. 6. Utilize sandboxing or isolated environments for opening untrusted MODEL files to contain potential exploitation. 7. Conduct regular security assessments and penetration testing focused on CAD environments to identify potential exposure. 8. Maintain comprehensive logging and alerting on AutoCAD process crashes or unusual activity to enable rapid incident response.
