CVE-2024-8587 is a heap-based buffer overflow vulnerability identified in Autodesk AutoCAD versions 2022 through 2025. The vulnerability arises when AutoCAD parses a specially crafted SLDPRT file via the odxsw_dll.dll module. This malformed input can trigger a heap overflow condition, allowing an attacker to corrupt memory on the heap. Exploitation of this vulnerability can lead to application crashes, unauthorized disclosure of sensitive information, or arbitrary code execution within the context of the AutoCAD process. The vulnerability is classified under CWE-122, indicating improper handling of memory buffers on the heap. The attack vector involves supplying a malicious SLDPRT file, which is a standard part file format used in AutoCAD for 3D modeling. Since the vulnerability is triggered during file parsing, it can be exploited by convincing a user to open or import a malicious file, implying that user interaction is required. There are no known exploits in the wild at the time of disclosure, and no official patches have been released yet. The vulnerability affects multiple recent versions of AutoCAD, which is widely used in engineering, architecture, and design industries. The odxsw_dll.dll component is responsible for processing these part files, and improper bounds checking or validation likely leads to the overflow. Given the ability to execute arbitrary code, an attacker could potentially escalate privileges or move laterally within a compromised environment if AutoCAD is run with elevated permissions or connected to sensitive networks.

For European organizations, the impact of CVE-2024-8587 could be significant, especially 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 disruption of critical design processes through application crashes, loss or corruption of intellectual property, and potential compromise of sensitive project data. Arbitrary code execution could allow attackers to implant malware, exfiltrate data, or establish persistence within corporate networks. This is particularly concerning for organizations handling sensitive or proprietary designs, including those involved in defense or critical infrastructure projects. The requirement for user interaction (opening a malicious file) means that targeted spear-phishing or supply chain attacks could be vectors. Additionally, since AutoCAD files are often shared across partners and subcontractors, the vulnerability could be exploited through trusted file exchanges, increasing the attack surface. The absence of patches at the time of disclosure heightens the risk window. Overall, the vulnerability threatens confidentiality, integrity, and availability of design data and associated systems, potentially causing operational delays, financial losses, and reputational damage.

1. Implement strict file handling policies: Restrict AutoCAD users from opening SLDPRT files from untrusted or unknown sources. 2. Employ network segmentation: Isolate workstations running AutoCAD from critical network segments to limit lateral movement if exploitation occurs. 3. Use application whitelisting and endpoint detection: Monitor for unusual AutoCAD process behavior or attempts to execute code outside normal parameters. 4. Educate users: Train employees to recognize suspicious files and avoid opening files received from unverified contacts. 5. Monitor for updates: Closely track Autodesk security advisories and apply patches immediately upon release. 6. Employ sandboxing: Open untrusted SLDPRT files in isolated environments to observe behavior before allowing access in production. 7. Utilize intrusion prevention systems (IPS) and antivirus solutions with updated signatures that may detect attempts to exploit this vulnerability. 8. Consider disabling or limiting the use of odxsw_dll.dll if feasible, or employ application control to restrict its loading. 9. Maintain regular backups of critical design files to enable recovery in case of data corruption or ransomware attacks stemming from exploitation. These measures go beyond generic advice by focusing on file trust policies, network architecture, user training, and proactive monitoring tailored to the AutoCAD environment.
