CVE-2025-1275 is a high-severity heap-based buffer overflow vulnerability (CWE-122) affecting Autodesk Revit versions 2023, 2024, and 2025. The vulnerability arises when a maliciously crafted JPG file is linked or imported into the application. This specially crafted image file triggers a heap overflow condition, allowing an attacker to corrupt memory in the context of the Revit process. Exploitation can lead to application crashes, unauthorized reading of sensitive data from memory, or arbitrary code execution with the privileges of the current user running Revit. The vulnerability requires local access to the system (Attack Vector: Local) and user interaction (UI:R) to import or link the malicious JPG file. No privileges are required to exploit the vulnerability (PR:N), but the attacker must convince the user to perform the import action. The vulnerability impacts confidentiality, integrity, and availability, as it can disclose sensitive project data, alter application behavior, or cause denial of service. The CVSS v3.1 base score is 7.8, reflecting high severity due to the potential for remote code execution and data compromise. No known exploits are currently reported in the wild, and no patches have been published yet. Autodesk Revit is a widely used Building Information Modeling (BIM) software in architecture, engineering, and construction sectors, making this vulnerability significant for organizations relying on these workflows. The heap overflow nature of the flaw suggests that exploitation may be complex but feasible, especially for skilled attackers targeting specific organizations or projects.

For European organizations, especially those in architecture, engineering, construction, and related industries, this vulnerability poses a substantial risk. Revit is commonly used across Europe for designing and managing building projects, including critical infrastructure and commercial developments. Exploitation could lead to unauthorized disclosure of sensitive design data, intellectual property theft, or sabotage of project files, potentially causing financial loss and reputational damage. The ability to execute arbitrary code could allow attackers to establish persistence, move laterally within corporate networks, or deploy ransomware. Given the local attack vector and user interaction requirement, insider threats or targeted phishing campaigns could facilitate exploitation. Additionally, disruption of Revit workflows could delay project timelines, impacting business operations. The confidentiality and integrity impacts are particularly concerning for organizations handling government contracts or critical infrastructure projects subject to strict regulatory compliance in Europe, such as GDPR and NIS Directive requirements.

European organizations should implement a multi-layered mitigation strategy beyond generic patching advice. First, restrict Revit usage to trusted users and environments, minimizing exposure to untrusted files. Implement strict file validation and scanning policies for all imported image files, using advanced malware detection tools capable of analyzing JPG content for anomalies. Educate users on the risks of importing files from unverified sources and enforce policies to avoid opening suspicious attachments or downloads. Employ application whitelisting and sandboxing techniques to limit the impact of potential exploitation. Monitor Revit process behavior and system logs for unusual activity indicative of exploitation attempts, such as unexpected crashes or memory access violations. Network segmentation should isolate systems running Revit from critical infrastructure to contain potential breaches. Since no patches are currently available, coordinate closely with Autodesk for timely updates and apply them immediately upon release. Finally, consider implementing endpoint detection and response (EDR) solutions with heuristics tuned to detect heap overflow exploitation patterns.
