Overview

CVE-2025-54260 is a critical vulnerability that exists in Substance3D – Modeler versions 1.22.2 and earlier. The vulnerability could lead to an out-of-bounds read when parsing a specially crafted file, potentially allowing an attacker to execute arbitrary code. This vulnerability is of high concern as it could potentially allow unauthorized access to systems and data, subject to the privileges of the user running the application.

How the Exploit Works

The exploit takes advantage of an out-of-bounds read vulnerability in Substance3D – Modeler. When the application parses a maliciously crafted file, it can result in a read past the end of an allocated memory structure. An attacker can craft a specific file that, when opened by the application, triggers the vulnerability and executes code within the context of the current user.

Conceptual Example Code

This is a conceptual example and does not reflect a specific code that could exploit this vulnerability. However, the exploit would likely involve a crafted file that triggers the out-of-bounds read.

# Pseudo code for crafted file
crafted_file = {
"header": "valid header",
"data": "valid data",
"malicious_code": "code that triggers out-of-bounds read"
}

The malicious_code part is crafted in such a way that it triggers the out-of-bounds read when the application tries to parse the file, leading to the execution of the malicious code.
