CVE-2025-54186

5.5 MEDIUM

📋 TL;DR

Substance3D Modeler versions 1.22.0 and earlier contain an out-of-bounds read vulnerability that could allow attackers to read sensitive memory contents. Users who open malicious files with affected versions are vulnerable to potential information disclosure.

💻 Affected Systems

Products:
  • Adobe Substance3D Modeler
Versions: 1.22.0 and earlier
Operating Systems: Windows, macOS
Default Config Vulnerable: ⚠️ Yes
Notes: All installations of affected versions are vulnerable when processing 3D model files.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

An attacker could craft a malicious file that, when opened, reads sensitive memory contents potentially containing credentials, encryption keys, or other confidential data from the application's memory space.

🟠

Likely Case

Limited information disclosure from the application's memory, potentially revealing fragments of data but not full system compromise.

🟢

If Mitigated

No impact if users only open trusted files from verified sources.

🌐 Internet-Facing: LOW - Exploitation requires user interaction to open malicious files, not directly exploitable over network.
🏢 Internal Only: MEDIUM - Internal users could be tricked into opening malicious files via email or shared drives.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Requires user interaction (opening malicious file) and crafting of specific file format to trigger out-of-bounds read.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 1.23.0 or later

Vendor Advisory: https://helpx.adobe.com/security/products/substance3d-modeler/apsb25-76.html

Restart Required: No

Instructions:

1. Open Substance3D Modeler. 2. Go to Help > Check for Updates. 3. Install available update to version 1.23.0 or later. 4. Verify update completed successfully.

🔧 Temporary Workarounds

Restrict file sources

all

Only open Substance3D Modeler files from trusted, verified sources

Use file validation

all

Implement file validation/sandboxing for unknown 3D model files

🧯 If You Can't Patch

  • Implement application whitelisting to restrict which users can run Substance3D Modeler
  • Deploy endpoint protection that can detect and block malicious 3D model files

🔍 How to Verify

Check if Vulnerable:

Check Substance3D Modeler version in application (Help > About). If version is 1.22.0 or earlier, system is vulnerable.

Check Version:

Not applicable - check via application GUI Help > About

Verify Fix Applied:

Verify version is 1.23.0 or later in Help > About menu.

📡 Detection & Monitoring

Log Indicators:

  • Application crashes when opening 3D files
  • Unusual memory access patterns in application logs

Network Indicators:

  • Downloads of 3D model files from untrusted sources
