CVE-2025-54187: Out-of-Bounds Write Vulnerability in Substance3D – Painter Resulting in Arbitrary Code Execution

Overview

A critical vulnerability, CVE-2025-54187, has been discovered in Substance3D – Painter versions 11.0.2 and earlier, which could potentially lead to arbitrary code execution in the context of the current user. This vulnerability is of high concern due to its ability to compromise system integrity and result in possible data leakage. The exploitation of this vulnerability requires user interaction, such as opening a malicious file, making the issue more significant as it raises the potential for social engineering attacks.

Substance3D – Painter | 11.0.2 and earlier

How the Exploit Works

The vulnerability arises from an out-of-bounds write condition within Substance3D – Painter. An attacker can craft a malicious file that, when opened in Substance3D – Painter, triggers this condition and leads to an overflow of data beyond the allocated memory boundaries. This overflow can overwrite other data and can potentially be exploited to execute arbitrary code in the software’s context.

Conceptual Example Code

Given the nature of this vulnerability, a direct HTTP request or shell command example may not be applicable. However, conceptually, the exploit process might involve the creation of a specially crafted file that triggers the out-of-bounds write condition when opened in Substance3D – Painter.

# Pseudocode
malicious_file = create_malicious_file() # Function to create a file that triggers out-of-bounds write
send_malicious_file_to_victim(malicious_file) # Function to send the file to the victim

In this pseudocode, `create_malicious_file` represents a function that creates a file designed to trigger the out-of-bounds write condition in Substance3D – Painter. The `send_malicious_file_to_victim` function represents the method used to deliver the malicious file to the victim, which could be through phishing, social engineering, or other means.

Mitigation

To mitigate this vulnerability, users are urged to apply the vendor-supplied patch as soon as it is available. In the interim, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) may provide temporary mitigation. However, these measures do not guarantee complete protection, and patching the affected software remains the most effective solution.
