CVE-2025-6637 is a high-severity vulnerability classified as CWE-787, an Out-of-Bounds Write, affecting Autodesk Shared Components version 2026.2. This vulnerability arises when a specially crafted PRT (part) file is parsed by certain Autodesk products that utilize these shared components. The flaw allows an attacker to write data outside the bounds of allocated memory buffers, which can lead to memory corruption. Exploitation can cause application crashes, data corruption, or potentially arbitrary code execution within the context of the affected process. The vulnerability requires local access (AV:L), no privileges (PR:N), but does require user interaction (UI:R) to open or process the malicious PRT file. The scope is unchanged (S:U), meaning the impact is limited to the vulnerable component without affecting other system components. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability. Although no known exploits are reported in the wild yet, the nature of the vulnerability—memory corruption leading to code execution—makes it a critical concern for organizations using Autodesk products, especially those handling sensitive design and engineering data. The vulnerability is present in a shared component, which may be used by multiple Autodesk applications, potentially broadening the attack surface if multiple products are installed.

For European organizations, the impact of CVE-2025-6637 can be significant, particularly in industries relying heavily on Autodesk software such as manufacturing, automotive, aerospace, architecture, and engineering. Successful exploitation could lead to unauthorized code execution, enabling attackers to compromise intellectual property, disrupt design workflows, or implant persistent malware. Data corruption could result in loss or alteration of critical design files, causing operational delays and financial losses. The requirement for user interaction means phishing or social engineering could be vectors for attack, increasing risk in environments with less stringent user training. Additionally, the local attack vector suggests that attackers may need some level of access to the victim’s environment, but this could be achieved through compromised user accounts or insider threats. The confidentiality impact is high, as design files often contain proprietary information. Integrity and availability impacts are also high, given the potential for data corruption and application crashes. The lack of known exploits in the wild currently reduces immediate risk but does not preclude future exploitation, especially as threat actors often develop exploits for high-impact vulnerabilities once disclosed.

To mitigate CVE-2025-6637, European organizations should: 1) Apply patches or updates from Autodesk as soon as they become available, as no patch links are currently provided but monitoring Autodesk advisories is critical. 2) Implement strict file handling policies to restrict opening PRT files from untrusted or unknown sources, including disabling automatic parsing or previewing of such files where possible. 3) Employ endpoint protection solutions capable of detecting anomalous behavior related to memory corruption or code execution attempts within Autodesk processes. 4) Conduct user awareness training focused on the risks of opening unsolicited or suspicious design files, emphasizing social engineering vectors. 5) Use application whitelisting and sandboxing techniques to limit the impact of potential exploitation by isolating Autodesk applications from critical system components. 6) Monitor logs and system behavior for crashes or unusual activity in Autodesk applications that could indicate attempted exploitation. 7) Restrict local user privileges to minimize the ability of attackers to execute malicious code even if a file is opened. These measures go beyond generic advice by focusing on controlling file sources, user behavior, and application isolation specific to the Autodesk environment.
