CVE-2025-54202 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe Substance3D - Modeler versions 1.22.0 and earlier. This vulnerability arises when the software improperly handles memory bounds while processing certain inputs, specifically when opening crafted malicious files. An out-of-bounds read can cause the application to read memory locations outside the intended buffer, potentially disclosing sensitive information stored in adjacent memory areas. Exploitation requires user interaction, meaning the victim must open a maliciously crafted file to trigger the vulnerability. The CVSS v3.1 base score is 5.5 (medium severity), reflecting that the attack vector is local (AV:L), with low attack complexity (AC:L), no privileges required (PR:N), but user interaction is necessary (UI:R). The impact is primarily on confidentiality (C:H), with no impact on integrity or availability. No known exploits are reported in the wild, and no patches are currently linked, indicating that mitigation may rely on vendor updates or user caution. This vulnerability is significant because Adobe Substance3D - Modeler is used in 3D content creation workflows, and disclosure of sensitive memory could leak proprietary or confidential project data.

For European organizations, the impact of this vulnerability could be notable in industries relying on 3D modeling and digital content creation, such as automotive design, manufacturing, gaming, media, and architecture. Disclosure of sensitive memory could expose intellectual property, trade secrets, or confidential project details, potentially leading to competitive disadvantage or regulatory compliance issues under GDPR if personal data is inadvertently exposed. Since exploitation requires user interaction and opening a malicious file, targeted spear-phishing or supply chain attacks could be vectors. The medium severity score suggests moderate risk, but the confidentiality impact is high, which is critical for organizations handling sensitive or proprietary data. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once the vulnerability is public.

To mitigate this vulnerability, European organizations should: 1) Immediately monitor Adobe's official channels for patches or updates addressing CVE-2025-54202 and apply them promptly once available. 2) Implement strict file handling policies, including restricting the opening of untrusted or unsolicited 3D model files within Substance3D - Modeler. 3) Educate users on the risks of opening files from unknown or unverified sources to reduce the likelihood of user interaction exploitation. 4) Employ endpoint protection solutions capable of detecting anomalous behavior related to file parsing or memory access in Substance3D - Modeler. 5) Consider sandboxing or isolating the application environment to limit potential data exposure if exploitation occurs. 6) Conduct regular audits of software versions in use to ensure outdated versions are identified and upgraded. These steps go beyond generic advice by focusing on user behavior, software lifecycle management, and environment hardening specific to the affected product and vulnerability characteristics.
