CVE-2025-2497 is a heap-based buffer overflow vulnerability identified in Autodesk Revit versions 2024 and 2025. The vulnerability arises when the application parses a maliciously crafted DWG file, a common file format used for CAD drawings. Specifically, the flaw is a heap-based buffer overflow (CWE-122), which occurs when the software improperly handles input data size, leading to memory corruption. This memory corruption can be exploited by an attacker to execute arbitrary code within the context of the Revit process. The vulnerability does not require user authentication but does require the user to open or import a malicious DWG file into Revit. There are no known exploits in the wild at the time of publication, and no patches have been released yet. However, the vulnerability is significant because Revit is widely used in architecture, engineering, and construction (AEC) industries for building information modeling (BIM). Successful exploitation could allow attackers to compromise the confidentiality, integrity, and availability of systems running Revit, potentially leading to unauthorized access, data theft, or disruption of critical design workflows.

For European organizations, especially those in the AEC sector, this vulnerability poses a substantial risk. Autodesk Revit is extensively used across Europe in large engineering firms, architectural studios, and construction companies. Exploitation could lead to unauthorized code execution, enabling attackers to implant malware, steal intellectual property such as proprietary building designs, or disrupt project timelines. Given the critical nature of infrastructure projects in Europe, such disruptions could have cascading effects on supply chains and regulatory compliance. Furthermore, compromised systems could be leveraged as entry points for broader network intrusions, threatening sensitive client data and potentially violating GDPR requirements. The medium severity rating suggests moderate ease of exploitation but significant potential impact, emphasizing the need for timely mitigation to protect the integrity of design and construction processes.

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Restrict the handling of DWG files to trusted sources only; implement strict file validation and scanning for malicious content before importing into Revit. 2) Employ application whitelisting and sandboxing techniques to isolate Revit processes, limiting the impact of any potential code execution. 3) Monitor network and endpoint activity for unusual behavior indicative of exploitation attempts, such as unexpected process spawning or memory anomalies. 4) Educate users on the risks of opening unverified DWG files and enforce policies to avoid importing files from unknown or untrusted origins. 5) Coordinate with Autodesk for timely patch deployment once available and consider temporary use of alternative software or disabling DWG import features if feasible. 6) Implement robust backup and recovery procedures to minimize downtime in case of successful exploitation. These targeted actions go beyond generic advice by focusing on controlling the attack vector (malicious DWG files) and limiting the execution context.
