CVE-2025-54198

5.5 MEDIUM

📋 TL;DR

CVE-2025-54198 is an out-of-bounds read vulnerability in Substance3D Modeler that could allow attackers to read sensitive memory contents when a victim opens a malicious file. This affects users of Substance3D Modeler versions 1.22.0 and earlier who open untrusted 3D model files.

💻 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 exfiltrate sensitive data from the application's memory, potentially including authentication tokens, encryption keys, or other confidential information stored in memory during file processing.

🟠

Likely Case

Limited information disclosure from application memory, potentially revealing some internal application state or previously processed data fragments.

🟢

If Mitigated

No impact if users only open trusted files from verified sources and the application is properly patched.

🌐 Internet-Facing: LOW - Exploitation requires user interaction to open malicious files, not network-accessible services.
🏢 Internal Only: MEDIUM - Internal users could be targeted via phishing or shared malicious files, but still requires user interaction.

🎯 Exploit Status

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

Exploitation requires user interaction (opening malicious file) and knowledge of memory layout. No public exploits known at this time.

🛠️ 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. Follow prompts to update to version 1.23.0 or later. 4. Alternatively, download latest version from Adobe Creative Cloud.

🔧 Temporary Workarounds

Restrict untrusted file processing

all

Configure application or system policies to prevent opening untrusted .sbsar or other 3D model files from unknown sources.

🧯 If You Can't Patch

  • Implement application whitelisting to restrict execution of vulnerable Substance3D Modeler versions
  • Educate users to never open 3D model files from untrusted or unknown sources

🔍 How to Verify

Check if Vulnerable:

Open Substance3D Modeler, go to Help > About, check if version is 1.22.0 or earlier.

Check Version:

Not applicable - check via application GUI Help > About menu

Verify Fix Applied:

After updating, verify version is 1.23.0 or later in Help > About.

📡 Detection & Monitoring

Log Indicators:

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

Network Indicators:

  • Outbound connections following file processing that could indicate data exfiltration

SIEM Query:

EventID=4688 AND ProcessName='Substance3D Modeler.exe' AND CommandLine CONTAINS '.sbsar' OR EventID=1000 AND Application='Substance3D Modeler.exe'
