CVE-2025-5037 is a high-severity buffer overflow vulnerability (CWE-120) found in Autodesk Revit versions 2023 through 2026. The flaw arises from improper handling of input sizes when parsing certain file formats used by Revit—specifically RFA, RTE, and RVT files. These file types are native to Revit and commonly used for architectural and engineering design data exchange. An attacker can craft a maliciously designed file that, when opened or processed by a vulnerable Revit instance, triggers a buffer copy operation without verifying the input size, leading to memory corruption. This memory corruption can be exploited to execute arbitrary code within the context of the Revit process. The vulnerability requires local access (attack vector: local) and user interaction (opening the malicious file), but no privileges or authentication are needed. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability. While no public exploits are currently known, the potential for arbitrary code execution makes this a critical concern for organizations relying on Revit for building information modeling (BIM).

For European organizations, especially those in architecture, engineering, construction, and related sectors, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized code execution, potentially allowing attackers to steal sensitive design data, disrupt project workflows, or establish persistence within corporate networks. Given Revit's widespread use in Europe for infrastructure and building projects, exploitation could impact intellectual property confidentiality and operational continuity. The local attack vector and requirement for user interaction mean that social engineering or phishing campaigns delivering malicious Revit files could be effective. Additionally, compromised systems could serve as footholds for lateral movement or ransomware deployment, amplifying the threat to European enterprises and critical infrastructure projects.

To mitigate this vulnerability, European organizations should: 1) Immediately apply patches or updates from Autodesk once available; currently, no patches are listed, so monitoring Autodesk advisories is critical. 2) Implement strict file validation and scanning policies for all Revit files received from external sources, including sandboxing or opening files in isolated environments before use. 3) Educate users on the risks of opening unsolicited or unexpected Revit files, emphasizing cautious handling of files from untrusted origins. 4) Employ endpoint protection solutions capable of detecting anomalous behavior related to memory corruption or code execution within Revit processes. 5) Restrict local user permissions to limit the ability to execute arbitrary code or install software, reducing the impact of exploitation. 6) Maintain robust network segmentation to contain potential compromises originating from infected workstations. 7) Monitor logs and system behavior for signs of exploitation attempts, including unusual Revit process activity or crashes.
