CVE-2025-54189
📋 TL;DR
Substance3D Painter versions 11.0.2 and earlier contain an out-of-bounds read vulnerability that could allow attackers to read sensitive memory contents. This affects users who open malicious project files, potentially exposing confidential data like passwords or encryption keys. Only users of Substance3D Painter 11.0.2 and earlier are vulnerable.
💻 Affected Systems
- Adobe Substance3D Painter
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could read sensitive memory contents including passwords, encryption keys, or other confidential data from the application's memory space, potentially leading to credential theft or further system compromise.
Likely Case
Limited information disclosure from the application's memory, potentially exposing some user data or system information but unlikely to lead to full system compromise.
If Mitigated
With proper controls, the impact is minimal as it requires user interaction and only affects the application's memory space, not the underlying operating system.
🎯 Exploit Status
Exploitation requires user interaction (opening a malicious file) and knowledge of memory layout. No public exploits are known at this time.
