CVE-2025-54275 identifies an out-of-bounds write vulnerability (CWE-787) in Adobe Substance3D - Viewer, a software tool used for viewing 3D content. The vulnerability exists in versions 0.25.2 and earlier, where improper bounds checking during file processing allows an attacker to write data outside the intended memory buffer. This memory corruption can cause the application to crash, resulting in a denial-of-service condition. Exploitation requires that a victim user opens a maliciously crafted file, making user interaction necessary. The vulnerability does not allow for code execution or data leakage but impacts application availability. The CVSS 3.1 base score is 5.5, reflecting a medium severity with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), no confidentiality or integrity impact (C:N/I:N), and high availability impact (A:H). No patches or exploits are currently known, but the risk lies in potential disruption of workflows relying on the Substance3D - Viewer application. The vulnerability highlights the importance of secure memory handling in file parsing components of creative software.

For European organizations, especially those in digital media, design, and manufacturing sectors that utilize Adobe Substance3D - Viewer, this vulnerability could lead to operational disruptions due to application crashes. While it does not compromise sensitive data or allow unauthorized code execution, denial-of-service conditions can delay project timelines and reduce productivity. Organizations relying on automated or batch processing of 3D files may experience interruptions if malicious or malformed files are introduced, whether inadvertently or through targeted attacks. The requirement for user interaction limits large-scale automated exploitation but does not eliminate risk from social engineering or insider threats. The impact is primarily on availability, which can be critical in time-sensitive creative workflows and collaborative environments common in European creative industries.

To mitigate this vulnerability, organizations should implement strict file handling policies, including verifying the source and integrity of 3D files before opening them in Substance3D - Viewer. User training to recognize suspicious files and avoid opening untrusted attachments is essential. Employ application whitelisting and sandboxing techniques to isolate the viewer application and limit the impact of crashes. Monitor Adobe’s security advisories closely for patches or updates addressing this vulnerability and apply them promptly once available. Additionally, consider using alternative tools or workflows that do not rely solely on the vulnerable software until a fix is released. Implementing endpoint detection and response (EDR) solutions can help detect abnormal application crashes that may indicate exploitation attempts. Regular backups of critical project files ensure recovery in case of disruption.
