CVE-2024-41861
📋 TL;DR
CVE-2024-41861 is an out-of-bounds read vulnerability in Adobe Substance3D Sampler that could allow an attacker to read sensitive memory contents. This affects users of Substance3D Sampler versions 4.5 and earlier who open malicious files. The vulnerability could help bypass security mitigations like ASLR.
💻 Affected Systems
- Adobe Substance3D Sampler
📦 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.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) and knowledge of memory layout. No public exploits have been reported as of the advisory date.
🛠️ Fix & Mitigation
✅ Official Fix
