CVE-2025-1430 is a classic buffer overflow vulnerability (CWE-120) found in Autodesk AutoCAD versions 2022 through 2025. The vulnerability arises when AutoCAD parses maliciously crafted SLDPRT files, which are part files typically used in CAD software for 3D modeling. Specifically, the flaw involves a buffer copy operation that does not properly check the size of the input data before copying it into a fixed-size buffer. This unchecked copy can lead to memory corruption, allowing an attacker to overwrite adjacent memory regions. Exploiting this vulnerability could enable an attacker to execute arbitrary code within the context of the AutoCAD process. This means that if a user opens or previews a specially crafted SLDPRT file, the attacker could potentially run malicious code with the same privileges as the user running AutoCAD. No authentication or elevated privileges are required to trigger this vulnerability, and no user interaction beyond opening or previewing the malicious file is necessary. Although no known exploits are currently reported in the wild, the nature of the vulnerability and the widespread use of AutoCAD in engineering and design environments make it a significant risk. The vulnerability affects multiple recent versions of AutoCAD, indicating a long window of exposure for users who have not updated or patched their software. The lack of an official patch at the time of this report increases the urgency for mitigation through other means.

For European organizations, especially those in engineering, architecture, manufacturing, and construction sectors where AutoCAD is heavily used, this vulnerability poses a substantial risk. Successful exploitation could lead to unauthorized code execution, potentially resulting in data theft, sabotage of design files, or lateral movement within corporate networks. Given that AutoCAD files are often shared internally and externally, the attack surface includes both internal users and external partners or contractors. The compromise of design data could have severe intellectual property implications, including loss of proprietary designs or exposure of sensitive project information. Additionally, disruption of AutoCAD operations could delay critical projects, impacting business continuity. The medium severity rating reflects the need for vigilance, as exploitation requires user interaction (opening a malicious file), but no authentication or elevated privileges. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits following public disclosure. European organizations with large engineering departments or those involved in critical infrastructure projects are particularly at risk due to the strategic importance of their design data and the widespread use of AutoCAD.

1. Implement strict file handling policies: Restrict the acceptance and opening of SLDPRT files from untrusted or unknown sources. Use sandbox environments to open and inspect files before allowing them into production systems. 2. Employ network segmentation: Isolate systems running AutoCAD from critical network segments to limit potential lateral movement in case of compromise. 3. Use application whitelisting and behavior monitoring: Deploy endpoint detection and response (EDR) solutions that can detect anomalous behavior indicative of exploitation attempts, such as unexpected code execution within AutoCAD processes. 4. Regularly back up design files and maintain version control: Ensure that backups are immutable and stored offline to prevent data loss or tampering. 5. Monitor vendor communications closely: Since no patch is currently available, stay alert for Autodesk updates or security advisories and apply patches immediately upon release. 6. Educate users: Train employees to recognize suspicious files and avoid opening attachments or downloads from unverified sources. 7. Consider disabling or limiting preview features in AutoCAD that automatically parse SLDPRT files, if feasible, to reduce the risk of accidental exploitation. 8. Use file integrity monitoring on directories where SLDPRT files are stored or transferred to detect unauthorized changes.
