CVE-2024-7305 is an out-of-bounds write vulnerability (CWE-787) found in Autodesk AutoCAD, specifically within the AdDwfPdk.dll component responsible for parsing DWF (Design Web Format) files. This vulnerability affects AutoCAD versions 2022 through 2025. When a maliciously crafted DWF file is processed, the vulnerability can trigger an out-of-bounds write operation, which may lead to memory corruption. The consequences of exploiting this flaw include application crashes, data corruption, or potentially arbitrary code execution within the context of the AutoCAD process. Since AutoCAD is widely used for computer-aided design (CAD) in engineering, architecture, and manufacturing, exploitation could allow attackers to disrupt workflows or gain code execution privileges on affected systems. The vulnerability does not currently have any known exploits in the wild, and no official patches have been released as of the publication date (August 19, 2024). The attack vector requires the victim to open or parse a malicious DWF file, which implies user interaction is necessary. The vulnerability does not require prior authentication but depends on the victim handling a crafted file. Given the nature of the vulnerability, exploitation could be leveraged for targeted attacks, especially in environments where AutoCAD is used to handle sensitive design data. The lack of a CVSS score necessitates an independent severity assessment based on impact and exploitability factors.

For European organizations, the impact of CVE-2024-7305 could be significant, particularly in sectors relying heavily on AutoCAD for design and engineering tasks, such as construction, manufacturing, automotive, aerospace, and infrastructure development. Successful exploitation could lead to denial of service through application crashes, resulting in operational disruption and productivity loss. More critically, arbitrary code execution could allow attackers to execute malicious payloads, potentially leading to data theft, sabotage of design files, or lateral movement within corporate networks. This could compromise intellectual property and sensitive project data, which are often valuable assets in European industries. Additionally, corrupted design files could cause errors in manufacturing or construction processes, leading to financial losses or safety risks. The requirement for user interaction (opening a malicious DWF file) limits mass exploitation but does not preclude targeted spear-phishing or supply chain attacks. The absence of known exploits currently reduces immediate risk but does not eliminate the threat, especially as threat actors may develop exploits once patches are released or if the vulnerability is reverse-engineered.

1. Implement strict file handling policies: Restrict AutoCAD users from opening DWF files from untrusted or unknown sources. Use email filtering and endpoint protection to block suspicious attachments. 2. Employ sandboxing: Run AutoCAD in isolated environments or virtual machines where possible to contain potential exploitation impact. 3. Monitor and alert: Deploy endpoint detection and response (EDR) tools to monitor for unusual AutoCAD process behavior or memory corruption indicators. 4. Network segmentation: Limit AutoCAD workstations' network access to reduce lateral movement opportunities if exploitation occurs. 5. Backup and integrity checks: Maintain regular backups of design files and implement file integrity monitoring to detect corruption early. 6. Stay updated: Although no patches are currently available, closely monitor Autodesk advisories and apply security updates promptly once released. 7. User awareness training: Educate users about the risks of opening unsolicited or unexpected DWF files, emphasizing cautious handling of design files received via email or external sources. 8. Consider application whitelisting to prevent unauthorized code execution within AutoCAD processes. These measures, combined, reduce the attack surface and mitigate potential exploitation consequences beyond generic patching advice.
