CVE-2025-54274 is a stack-based buffer overflow vulnerability classified under CWE-121, affecting Adobe Substance3D - Viewer versions 0.25.2 and earlier. This vulnerability arises from improper handling of input data when processing files, allowing an attacker to overwrite the stack memory. Successful exploitation requires the victim to open a specially crafted malicious file, which triggers the buffer overflow. This can lead to arbitrary code execution within the context of the current user, potentially allowing attackers to execute malicious payloads, escalate privileges if combined with other vulnerabilities, or disrupt application availability. The vulnerability has a CVSS v3.1 base score of 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity but requiring user interaction. No patches or updates are currently linked, and no known exploits have been reported in the wild, indicating the vulnerability is newly disclosed. Adobe Substance3D - Viewer is widely used in digital content creation, making this vulnerability relevant to creative professionals and organizations relying on Adobe's 3D asset tools. The vulnerability's exploitation vector is local file opening, emphasizing the importance of controlling file sources and user behavior.

For European organizations, the impact of CVE-2025-54274 can be significant, especially for those in industries such as digital media, animation, gaming, and product design that rely heavily on Adobe Substance3D - Viewer. Successful exploitation could lead to unauthorized code execution, data theft, or disruption of workflows. Confidentiality breaches could expose proprietary designs or intellectual property, while integrity compromises could corrupt critical 3D assets or project files. Availability impacts could interrupt creative processes, causing operational delays. Given the user interaction requirement, social engineering or phishing campaigns could be used to deliver malicious files. The vulnerability could also serve as a foothold for lateral movement within networks if combined with other vulnerabilities. Organizations with less mature endpoint security or insufficient user training are at higher risk. The absence of a patch increases exposure time, necessitating immediate mitigation efforts.

1. Restrict file sources by enforcing strict policies on opening files only from trusted origins and verified senders. 2. Implement application whitelisting to limit execution of unauthorized or suspicious files within Adobe Substance3D - Viewer. 3. Educate users on the risks of opening unsolicited or unexpected files, emphasizing caution with files received via email or external sources. 4. Monitor endpoint behavior for anomalies indicative of exploitation attempts, such as unexpected process spawning or memory corruption alerts. 5. Employ sandboxing or containerization for running Adobe Substance3D - Viewer to limit the impact of potential exploits. 6. Regularly review and update security policies to include emerging threats related to creative software tools. 7. Coordinate with Adobe for timely updates or patches and apply them promptly once available. 8. Use network segmentation to isolate systems running Substance3D - Viewer from critical infrastructure to reduce lateral movement risk.
