CVE-2024-47431

7.8 HIGH

📋 TL;DR

Substance3D Painter versions 10.1.0 and earlier contain a heap-based buffer overflow vulnerability that could allow attackers to execute arbitrary code on a victim's system. This affects users who open malicious files with the vulnerable software. Successful exploitation requires user interaction but could lead to full system compromise.

💻 Affected Systems

Products:
  • Adobe Substance3D Painter
Versions: 10.1.0 and earlier
Operating Systems: Windows, macOS, Linux
Default Config Vulnerable: ⚠️ Yes
Notes: All default installations of affected versions are vulnerable when processing malicious files.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system takeover with attacker gaining the same privileges as the logged-in user, potentially leading to data theft, ransomware deployment, or lateral movement.

🟠

Likely Case

Local privilege escalation or arbitrary code execution within the user context, allowing attackers to steal files, install malware, or compromise credentials.

🟢

If Mitigated

Limited impact if proper application sandboxing, least privilege principles, and file validation are implemented.

🌐 Internet-Facing: LOW - Exploitation requires local file access and user interaction, not directly exposed to internet attacks.
🏢 Internal Only: MEDIUM - Internal users could be targeted via phishing or malicious file shares, but requires user interaction to trigger.

🎯 Exploit Status

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

Exploitation requires user interaction (opening malicious file) and buffer overflow exploitation knowledge. No public exploits known at this time.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 10.2.0 or later
