CVE-2025-27180

5.5 MEDIUM

📋 TL;DR

CVE-2025-27180 is an out-of-bounds read vulnerability in Substance3D Modeler 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 Modeler versions 1.15.0 and earlier are affected.

💻 Affected Systems

Products:
  • Adobe Substance3D Modeler
Versions: 1.15.0 and earlier
Operating Systems: Windows, macOS
Default Config Vulnerable: ⚠️ Yes
Notes: All installations of affected versions are vulnerable by default when opening files.

📦 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 application data or system information that could aid in developing further attacks.

🟢

If Mitigated

Limited information disclosure with no direct code execution, though memory layout information could still be exposed.

🌐 Internet-Facing: LOW - Exploitation requires user interaction to open malicious files, not network-accessible services.
🏢 Internal Only: MEDIUM - Internal users could be targeted via phishing or shared malicious files, but still requires user interaction.

🎯 Exploit Status

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

Exploitation requires user interaction (opening malicious file) and knowledge of memory layout. No public exploits known at this time.

🛠️ Fix & Mitigation
