Overview
The CVE-2025-49572 is a significant vulnerability identified in Substance3D – Modeler versions 1.22.0 and earlier, posing a substantial security risk to users of the software. It is an out-of-bounds write vulnerability that could result in arbitrary code execution, potentially compromising the system security or leaking sensitive data. This vulnerability is especially concerning because it doesn’t require advanced privileges and the exploitation merely requires user interaction, such as opening a malicious file.

How the Exploit Works
The vulnerability occurs due to an out-of-bounds write in the Substance3D – Modeler. When a user opens a malicious file, the software fails to properly validate or sanitize the input data, leading to an out-of-bounds write condition. This could allow an attacker to overwrite critical memory locations with arbitrary data, potentially leading to arbitrary code execution. Consequently, an attacker could execute arbitrary commands or code within the context of the current user, potentially compromising the system or causing data leakage.
Conceptual Example Code
The following pseudocode illustrates conceptually how this vulnerability might be exploited. Please note that this is hypothetical and simplified for understanding purposes:
# Attacker creates a malicious file
malicious_file = create_malicious_file()
# Victim opens the malicious file in Substance3D - Modeler
substance3d_modeler.open(malicious_file)
# Due to the out-of-bounds write vulnerability, arbitrary code gets executed
execute_arbitrary_code(context_of_current_user)In this scenario, the attacker creates a malicious file that contains specifically crafted data that exploits the out-of-bounds write vulnerability when opened in Substance3D – Modeler. This leads to the execution of arbitrary code in the context of the current user.
Recommended Mitigations
The most effective mitigation for this vulnerability is to apply the patch provided by the vendor. If the patch cannot be immediately applied, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, these are only temporary solutions and cannot completely eliminate the risk. Therefore, it’s crucial to apply the vendor-provided patch as soon as possible to effectively mitigate this vulnerability.
