CVE-2025-49569 is a high-severity out-of-bounds write vulnerability (CWE-787) affecting Adobe Substance3D - Viewer versions 0.25 and earlier. This vulnerability arises when the application improperly handles memory boundaries during processing of certain input data, leading to the possibility of writing data outside the allocated buffer. Such out-of-bounds writes can corrupt memory, potentially allowing an attacker to execute arbitrary code within the context of the current user. Exploitation requires user interaction, specifically the victim opening a maliciously crafted file designed to trigger the vulnerability. The CVSS v3.1 base score is 7.8, reflecting a high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required, but user interaction is necessary. No patches or known exploits in the wild have been reported as of the publication date. Given the nature of the vulnerability, successful exploitation could lead to full compromise of the affected user's environment, including data theft, system manipulation, or further malware deployment. The vulnerability affects a specialized 3D content viewing application used primarily in digital content creation and visualization workflows.

For European organizations, especially those involved in digital media, design, gaming, and industrial visualization sectors, this vulnerability poses a significant risk. Compromise of systems running Adobe Substance3D - Viewer could lead to unauthorized access to sensitive intellectual property, design files, and proprietary data. Since the vulnerability allows arbitrary code execution with the privileges of the current user, attackers could leverage it to move laterally within corporate networks, escalate privileges, or deploy ransomware and other malware. The requirement for user interaction (opening a malicious file) suggests phishing or social engineering campaigns could be vectors for exploitation. Additionally, organizations relying on collaborative workflows involving 3D assets may face supply chain risks if malicious files are introduced via third parties. The lack of a patch increases exposure time, and the high CVSS score underscores the criticality of addressing this issue promptly to prevent potential data breaches and operational disruptions.

1. Immediate mitigation should include restricting the use of Adobe Substance3D - Viewer to trusted files and sources only, avoiding opening files from unverified or unknown origins. 2. Implement robust email and file filtering solutions to detect and block potentially malicious 3D asset files or attachments. 3. Employ endpoint detection and response (EDR) tools capable of monitoring and alerting on suspicious process behaviors related to Adobe Substance3D - Viewer. 4. Enforce the principle of least privilege by ensuring users operate with minimal necessary permissions to limit the impact of any successful exploitation. 5. Educate users on the risks of opening unsolicited or unexpected files, emphasizing caution with 3D asset files. 6. Monitor Adobe’s official channels for patches or updates addressing this vulnerability and apply them immediately upon release. 7. Consider network segmentation for systems handling sensitive 3D content to contain potential compromises. 8. Conduct regular security assessments and penetration testing focused on the software and its integration within the organizational environment to identify and remediate related risks.
