Overview

The cybersecurity community has recently identified a critical vulnerability, CVE-2025-2497, that poses a significant threat to users of Autodesk Revit, a popular software product used in the construction industry for designing and managing building projects. The vulnerability exploits a weakness in the way Autodesk Revit parses DWG files, a common file format used in the software. This vulnerability is crucial due to its potential to allow an attacker to execute arbitrary code in the context of the current process, potentially leading to system compromise or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-2497
Severity: High (7.8 CVSS)
Attack Vector: Local File
Privileges Required: None
User Interaction: Required
Impact: System Compromise, Data Leakage

Affected Products

Product | Affected Versions

Autodesk Revit | All versions prior to the vendor patch

How the Exploit Works

An attacker exploiting this vulnerability would prepare a maliciously crafted DWG file, designed to cause a Stack-Based Buffer Overflow when parsed by Autodesk Revit. This Overflow can then be used to execute arbitrary code on the victim’s machine. The code runs in the context of the current process, which means that if the user has administrative privileges, the attacker could gain complete control over the user’s system.

Conceptual Example Code

The following pseudocode provides a conceptual example of how this vulnerability might be exploited:
```
create DWG_file {
buffer: [256 bytes],
payload: {
data: [arbitrary code],
overflow: generateOverflow(256 bytes)
}
}
function generateOverflow(size) {
return new Array(size + 1).join('A');
}
send DWG_file to victim;
```
In this conceptual example, a DWG file is created with a buffer size of 256 bytes. The payload contains arbitrary code and an overflow generated by repeating the character ‘A’ more times than the buffer can handle. This overflow forces the buffer to overwrite adjacent memory, thus allowing the arbitrary code to be executed when the DWG file is opened in Autodesk Revit.

Mitigations

Users of affected versions of Autodesk Revit are advised to apply the vendor-supplied patch immediately. If the patch cannot be applied immediately, users should consider implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. Users should also exercise caution when opening DWG files, especially those received from untrusted sources.
