CVE-2025-54276 is an out-of-bounds read vulnerability classified under CWE-125 affecting Adobe Substance3D - Modeler versions 1.22.3 and earlier. The vulnerability arises during the parsing of a crafted file, where the software reads beyond the allocated memory buffer. This memory corruption can be leveraged by an attacker to execute arbitrary code with the privileges of the current user. The attack vector requires the victim to open a maliciously crafted file, making user interaction mandatory. The vulnerability impacts confidentiality, integrity, and availability, as arbitrary code execution can lead to data theft, modification, or system compromise. The CVSS 3.1 base score is 7.8, reflecting a high severity with local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), and user interaction required (UI:R). The vulnerability scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). No patches or exploits are currently publicly available, but the risk remains significant due to the potential for code execution. Adobe Substance3D - Modeler is widely used in digital content creation, making this vulnerability relevant to creative professionals and organizations relying on this software.

For European organizations, the impact of CVE-2025-54276 can be substantial, especially for those in industries such as digital media, gaming, advertising, and product design that rely heavily on Adobe Substance3D - Modeler. Successful exploitation could lead to unauthorized access to sensitive design files, intellectual property theft, or disruption of creative workflows. The arbitrary code execution capability could also serve as a foothold for further network compromise, lateral movement, or deployment of ransomware. Since exploitation requires user interaction, targeted phishing or social engineering campaigns could be used to deliver malicious files. The high confidentiality, integrity, and availability impacts mean that organizations could face data breaches, loss of trust, operational downtime, and financial losses. Additionally, regulatory compliance risks under GDPR may arise if personal or sensitive data is exposed or compromised due to this vulnerability.

European organizations should implement the following specific mitigations: 1) Immediately verify the Adobe Substance3D - Modeler version in use and upgrade to the latest patched version once available from Adobe. 2) Until patches are released, restrict the opening of files from untrusted or unknown sources within the application environment. 3) Implement application whitelisting and sandboxing to limit the execution context of Substance3D - Modeler and contain potential exploits. 4) Conduct targeted user awareness training focusing on the risks of opening files from unverified sources, emphasizing the need for caution with email attachments and downloads. 5) Employ endpoint detection and response (EDR) solutions to monitor for suspicious behaviors indicative of exploitation attempts. 6) Utilize network segmentation to isolate creative workstations and limit lateral movement in case of compromise. 7) Regularly back up critical design data and verify backup integrity to enable recovery from potential ransomware or data corruption incidents. 8) Monitor Adobe security advisories and threat intelligence feeds for updates or emerging exploit reports related to this vulnerability.
