A heap-based buffer overflow vulnerability in Autodesk Revit allows an attacker to execute arbitrary code or cause a system crash through the use of a specially crafted RTE file.

This is a heap-based buffer overflow (CWE-122) triggered when the application parses a malformed RTE file. The vulnerability requires user interaction, such as opening a malicious file, and can be exploited by an unauthenticated attacker to achieve remote code execution or unauthorized data access.

Successful exploitation poses a severe risk to organizational data and system integrity. Because this flaw allows for arbitrary code execution, an attacker could gain control over the local workstation, potentially leading to the theft of sensitive project intellectual property or lateral movement within the corporate network. With a CVSS score of 7.8, this vulnerability is classified as High severity.

Immediate Action: Update all instances of Autodesk Revit to the latest patched versions as specified in the Autodesk security advisory (ADSK-SA-2025-0012).

Proactive Monitoring: Monitor endpoint processes for unusual behavior or unexpected crashes associated with the Revit application.

Compensating Controls: Implement strict file access policies that prevent users from opening untrusted or unsolicited RTE files from external or unknown sources.

Public Exploit Available: No (exploit_available: false)

Given the potential for remote code execution, organizations should prioritize the deployment of the provided patches across all affected Revit environments. Users should be educated on the risks of opening files from untrusted sources to mitigate the primary vector of this vulnerability while updates are being applied.
