CVE-2024-52998
📋 TL;DR
CVE-2024-52998 is an out-of-bounds read vulnerability in Substance3D Stager that could allow an attacker to read sensitive memory contents when a victim opens a malicious file. This could potentially bypass security mitigations like ASLR. Users of Substance3D Stager versions 3.0.2 and earlier are affected.
💻 Affected Systems
- Adobe Substance3D Stager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could read sensitive memory contents, potentially obtaining credentials, encryption keys, or other confidential data, and bypass ASLR to enable further exploitation.
Likely Case
Information disclosure of random memory contents, potentially revealing some sensitive data but requiring additional vulnerabilities for full system compromise.
If Mitigated
Limited impact with proper file handling controls and user awareness about opening untrusted files.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) and understanding of memory layout for effective information disclosure.
