CVE-2024-41863

5.5 MEDIUM

📋 TL;DR

CVE-2024-41863 is an out-of-bounds read vulnerability in Adobe Substance3D Sampler that could allow an attacker to read sensitive memory contents when a user opens a malicious file. This could potentially bypass security mitigations like ASLR. Users of Substance3D Sampler versions 4.5 and earlier are affected.

💻 Affected Systems

Products:
  • Adobe Substance3D Sampler
Versions: 4.5 and earlier
Operating Systems: Windows, macOS
Default Config Vulnerable: ⚠️ Yes
Notes: All installations of affected versions are vulnerable by default when processing files.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

An attacker could read sensitive memory contents, potentially obtaining credentials, encryption keys, or other protected data, and use this information to bypass ASLR for further exploitation.

🟠

Likely Case

Limited information disclosure from memory, potentially revealing some application data but unlikely to lead to full system compromise without additional vulnerabilities.

🟢

If Mitigated

With proper controls, the impact is limited to potential information disclosure from the application's memory space only.

🌐 Internet-Facing: LOW - Exploitation requires user interaction (opening malicious file) and the software is typically not internet-facing.
🏢 Internal Only: MEDIUM - Internal users could be targeted via phishing or shared malicious files, requiring user interaction to trigger.

🎯 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: 4.5.1 or later

Vendor Advisory: https://helpx.adobe.com/security/products/substance3d-sampler/apsb24-65.html

Restart Required: Yes

Instructions:

1. Open Adobe Substance3D Sampler. 2. Go to Help > Check for Updates. 3. Follow prompts to install version 4.5.1 or later. 4. Restart the application.

🔧 Temporary Workarounds

Restrict file processing

all

Limit file processing to trusted sources only and avoid opening files from unknown or untrusted sources.

🧯 If You Can't Patch

  • Restrict user permissions to limit potential damage from information disclosure
  • Implement application whitelisting to prevent execution of malicious payloads
