CVE-2025-5038 is a high-severity buffer overflow vulnerability classified under CWE-120, affecting Autodesk Shared Components version 2026.2. The vulnerability arises from improper handling of input size during the parsing of X_T files, which are typically used in CAD and 3D modeling workflows. Specifically, a maliciously crafted X_T file can trigger a buffer copy operation without adequate size checks, leading to memory corruption. This memory corruption can be exploited by an attacker to execute arbitrary code within the context of the affected Autodesk process. The vulnerability requires local access (AV:L) but does not require privileges (PR:N) and involves user interaction (UI:R), such as opening or importing the malicious file. The scope is unchanged (S:U), meaning the impact is limited to the vulnerable component. The CVSS v3.1 base score is 7.8, reflecting high confidentiality, integrity, and availability impacts due to potential arbitrary code execution. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability is significant because Autodesk products are widely used in engineering, architecture, and manufacturing sectors, where compromised systems could lead to intellectual property theft, sabotage of design files, or disruption of critical workflows.

For European organizations, this vulnerability poses a substantial risk, especially those in industries reliant on Autodesk software such as automotive, aerospace, construction, and industrial design. Successful exploitation could lead to unauthorized code execution, enabling attackers to steal sensitive design data, implant malware, or disrupt production pipelines. Given the high confidentiality and integrity impact, intellectual property theft and data manipulation are primary concerns. Availability could also be affected if the exploit causes crashes or system instability. The requirement for user interaction means phishing or social engineering could be vectors to deliver malicious X_T files. The local attack vector suggests that insider threats or compromised endpoints could be leveraged. The lack of current exploits provides a window for proactive mitigation, but the high severity score indicates that organizations should prioritize addressing this vulnerability to avoid potential targeted attacks.

European organizations should implement the following specific mitigations: 1) Restrict access to Autodesk Shared Components and related software to trusted users only, minimizing exposure to untrusted files. 2) Educate users on the risks of opening X_T files from unknown or unverified sources to reduce the likelihood of successful social engineering. 3) Employ application whitelisting and sandboxing techniques for Autodesk applications to contain potential exploitation. 4) Monitor file integrity and usage patterns for unusual activity related to X_T files. 5) Maintain strict endpoint security controls, including up-to-date antivirus and endpoint detection and response (EDR) solutions capable of detecting anomalous behavior during file parsing. 6) Prepare for rapid deployment of patches once Autodesk releases updates by establishing a vulnerability management process focused on Autodesk products. 7) Consider network segmentation to isolate systems running Autodesk software from less secure network zones. 8) Implement logging and alerting on Autodesk application crashes or suspicious process behavior to enable early detection of exploitation attempts.
