CVE-2025-1275 is a heap-based buffer overflow vulnerability identified in Autodesk Revit versions 2023, 2024, and 2025. The vulnerability arises when a maliciously crafted JPG file is linked or imported into the application. Specifically, the flaw is triggered by improper handling of the JPG file data in memory, leading to a heap overflow condition. This type of vulnerability (CWE-122) occurs when data is written beyond the boundaries of allocated heap memory, potentially corrupting adjacent memory structures. Exploitation of this vulnerability can result in several adverse outcomes: forced application crashes (denial of service), unauthorized reading of sensitive data from memory, or execution of arbitrary code within the context of the Revit process. The arbitrary code execution capability means an attacker could potentially escalate privileges or execute malicious payloads on the affected system. Notably, exploitation requires the victim to import or link the crafted JPG file into Revit, implying some level of user interaction. There are no known exploits in the wild at the time of publication, and no patches have been released yet. Autodesk has acknowledged the vulnerability and assigned it a medium severity rating. The vulnerability affects multiple recent versions of Revit, a widely used Building Information Modeling (BIM) software in architecture, engineering, and construction industries.

For European organizations, the impact of CVE-2025-1275 can be significant, especially for those in architecture, engineering, construction, and related sectors that rely heavily on Autodesk Revit for design and project management. Successful exploitation could lead to unauthorized disclosure of sensitive design data, intellectual property theft, or disruption of critical workflows due to application crashes. In worst-case scenarios, arbitrary code execution could allow attackers to establish persistence within corporate networks, potentially leading to broader compromise. Given that Revit files often contain detailed building plans and infrastructure information, exposure could have implications for physical security and regulatory compliance. The medium severity rating reflects the need for caution but also the requirement of user interaction (importing a malicious JPG), which somewhat limits the attack vector. However, targeted spear-phishing or supply chain attacks embedding malicious JPGs in project files could increase risk. The absence of known exploits currently reduces immediate threat but does not preclude future exploitation. Organizations with extensive use of Revit in critical infrastructure projects or government contracts should consider this vulnerability a priority for risk management.

1. Implement strict file validation and sandboxing: Until patches are available, restrict the import of JPG files from untrusted sources into Revit projects. Use file integrity monitoring and scanning tools to detect anomalous or suspicious image files. 2. User training and awareness: Educate users about the risks of importing files from unknown or unverified origins, emphasizing caution with project files containing embedded images. 3. Network segmentation: Isolate systems running Revit from broader corporate networks to limit lateral movement in case of exploitation. 4. Monitor application behavior: Deploy endpoint detection and response (EDR) solutions to identify abnormal Revit process behavior, such as unexpected crashes or memory access violations. 5. Maintain up-to-date backups: Regularly back up critical project data to enable recovery in case of disruption. 6. Engage with Autodesk: Monitor Autodesk advisories for patches or updates addressing this vulnerability and apply them promptly once available. 7. Use application whitelisting and least privilege: Limit the permissions of Revit processes to reduce the impact of potential code execution. 8. Consider disabling or restricting the import/linking of JPG files temporarily if feasible within project workflows.
