CVE-2025-54201 is an out-of-bounds read vulnerability (CWE-125) identified in Adobe Substance3D - Modeler versions 1.22.0 and earlier. This vulnerability arises when the software improperly handles memory boundaries, allowing an attacker to read memory locations outside the intended buffer. The consequence of this flaw is the potential disclosure of sensitive information residing in adjacent memory areas, which could include confidential data or cryptographic material. Exploitation requires user interaction, specifically the victim opening a crafted malicious file designed to trigger the out-of-bounds read condition. The vulnerability does not allow modification of data or denial of service but compromises confidentiality by leaking sensitive memory contents. The CVSS 3.1 base score is 5.5 (medium severity), reflecting a local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), high impact on confidentiality (C:H), and no impact on integrity or availability (I:N/A:N). No known public exploits or patches are currently available, indicating that the vulnerability is newly disclosed and may not yet be actively exploited in the wild. The issue affects a niche product used primarily for 3D modeling and content creation, which may limit the attack surface but still poses a risk to users who handle untrusted files in this application.

For European organizations, the primary impact of this vulnerability lies in the potential leakage of sensitive information through crafted files opened in Adobe Substance3D - Modeler. Organizations involved in digital content creation, media production, gaming, and design sectors that utilize this software could face confidentiality breaches if malicious files are introduced via email, file sharing, or insider threats. Although the vulnerability does not allow code execution or system compromise, the exposure of sensitive memory could lead to further targeted attacks or intellectual property theft. The requirement for user interaction reduces the risk of widespread automated exploitation but does not eliminate the threat, especially in environments where users frequently exchange 3D model files. Given the medium severity and local attack vector, the threat is more relevant to endpoint security and user awareness. European companies with creative teams using Adobe Substance3D - Modeler should be vigilant about file provenance and implement controls to prevent opening untrusted files. The absence of known exploits suggests a window of opportunity for proactive mitigation before attackers develop weaponized payloads.

1. Implement strict file validation and sandboxing: Configure Adobe Substance3D - Modeler to open files in a restricted environment or sandbox to limit potential memory exposure. 2. Enforce strict file origin policies: Educate users to only open 3D model files from trusted sources and implement email and file transfer scanning to detect potentially malicious files. 3. Monitor and restrict usage: Limit the installation and use of Substance3D - Modeler to essential personnel and isolate workstations handling untrusted content. 4. Apply application whitelisting and endpoint detection: Use endpoint security solutions to monitor for anomalous behavior related to the application. 5. Stay updated on vendor advisories: Since no patch is currently available, monitor Adobe’s security bulletins for updates or hotfixes and apply them promptly once released. 6. Employ memory protection technologies: Utilize operating system-level protections such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) to reduce exploitation risk. 7. Conduct user training: Raise awareness about the risks of opening unverified files and encourage reporting of suspicious files or behavior.
