CVE-2025-6633: Autodesk 3ds Max Out-of-Bounds Write Vulnerability Exploitation via RBG File

Overview

The Common Vulnerabilities and Exposures (CVE) system has identified a significant vulnerability labeled CVE-2025-6633. This vulnerability affects Autodesk 3ds Max, a powerful 3D modeling and rendering software used extensively in industries such as architecture, gaming, and film. When a maliciously crafted RBG file is parsed through the software, an Out-of-Bounds Write vulnerability can be triggered. This exploit is of critical concern as it may lead to system compromise, data corruption, or even arbitrary code execution within the context of the current process.

Vulnerability Summary

CVE ID: CVE-2025-6633

How the Exploit Works

The vulnerability is an Out-of-Bounds Write issue that arises when Autodesk 3ds Max software parses a maliciously crafted RBG file. An attacker can exploit this vulnerability by tricking a victim into opening the contaminated file using the software. This action can lead to an Out-of-Bounds Write, which, in turn, can force the software to crash, corrupt data, or worse, allow the attacker to execute arbitrary code within the context of the current process.

Conceptual Example Code

While the exact code to exploit this vulnerability is beyond the scope of this article, a conceptual illustration would involve crafting a malicious RBG file designed to trigger an Out-of-Bounds Write when parsed by Autodesk 3ds Max:

def create_malicious_rbg_file():
data = bytearray()
# Fill the data with specific bytes that cause an Out-of-Bounds Write when parsed by 3ds Max
# This is a conceptual example, the actual bytes would depend on the specific vulnerability in the software
data.extend(b'\x00\x00\x00\x00')
with open('malicious.rbg', 'wb') as file:
file.write(data)

In this hypothetical scenario, the attacker would then send this malicious RBG file to the victim, who, upon opening the file with Autodesk 3ds Max, would trigger the vulnerability.
Please note that this is a simplified and abstract representation of how such an exploit might work. The actual method to craft a malicious file that would exploit this vulnerability would be significantly more complex and is dependent on the specific details of the vulnerability.
