CVE-2024-47431
📋 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
- Adobe Substance3D Painter
📦 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.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) and buffer overflow exploitation knowledge. No public exploits known at this time.
