CVE-2024-9827 is an out-of-bounds read vulnerability (CWE-125) identified in Autodesk AutoCAD versions 2022 through 2025. The vulnerability arises from improper parsing of maliciously crafted CATPART files within the CC5Dll.dll component of AutoCAD. When such a file is processed, the application may read memory outside the intended buffer boundaries, leading to potential memory corruption. This flaw can be exploited by an attacker to cause a denial-of-service (application crash), leak sensitive information from memory, or potentially execute arbitrary code within the context of the AutoCAD process. Exploitation requires the victim to open or otherwise process a malicious CATPART file, which is a common file format used for 3D part models in CAD workflows. Although no public exploits are currently known, the vulnerability poses a risk due to the ability to execute code or access sensitive data, especially in environments where AutoCAD is used to handle proprietary design files. The vulnerability does not require authentication beyond the ability to open files in AutoCAD, and user interaction is necessary to trigger the flaw (i.e., opening the crafted file). The lack of a patch at the time of reporting increases the urgency for mitigation measures. Given the critical role of AutoCAD in engineering, manufacturing, and design sectors, this vulnerability could be leveraged for espionage or sabotage if exploited in targeted attacks.

For European organizations, the impact of CVE-2024-9827 could be significant, particularly in industries reliant on AutoCAD for product design, architecture, and engineering such as automotive, aerospace, construction, and manufacturing sectors. Successful exploitation could lead to unauthorized disclosure of sensitive intellectual property or design data, undermining competitive advantage and potentially violating data protection regulations. Additionally, arbitrary code execution could allow attackers to establish persistence, move laterally within networks, or deploy ransomware, disrupting critical infrastructure and business operations. The medium severity rating reflects the requirement for user interaction and the absence of widespread exploitation, but the potential for targeted attacks against high-value design assets elevates the risk profile. Organizations involved in collaborative design projects or those sharing CAD files externally are particularly vulnerable to supply chain or phishing-based attack vectors. The vulnerability could also affect government agencies and defense contractors in Europe that utilize AutoCAD for sensitive projects, increasing the risk of espionage or sabotage.

Given the absence of an official patch, European organizations should implement several specific mitigation strategies: 1) Enforce strict validation and scanning of all incoming CATPART files using sandboxed or isolated environments before opening them in AutoCAD to detect malicious content. 2) Restrict AutoCAD usage to trusted users and limit file sharing to verified sources to reduce exposure to crafted files. 3) Employ application whitelisting and endpoint detection and response (EDR) tools to monitor and block anomalous behavior indicative of exploitation attempts, such as unexpected crashes or code execution within AutoCAD processes. 4) Educate users on the risks of opening unsolicited or unverified CAD files, emphasizing the importance of verifying file origins. 5) Where possible, run AutoCAD with the least privileges necessary to limit the impact of potential code execution. 6) Maintain robust network segmentation to isolate design environments from critical infrastructure and sensitive data stores. 7) Monitor vendor communications closely for patches or updates and plan for rapid deployment once available. These measures go beyond generic advice by focusing on file validation, user training, and environment hardening tailored to the specific attack vector of malicious CATPART files.
