CVE-2025-47108 is a high-severity out-of-bounds write vulnerability (CWE-787) affecting Adobe Substance3D - Painter versions 11.0.1 and earlier. This vulnerability arises when the software improperly handles memory boundaries, allowing an attacker to write data outside the allocated buffer. Such memory corruption can lead to arbitrary code execution within the context of the current user. Exploitation requires user interaction, specifically opening a maliciously crafted file designed to trigger the vulnerability. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required, but user interaction is necessary. The vulnerability could allow attackers to execute arbitrary code, potentially leading to data theft, system compromise, or further malware deployment. No known exploits are currently reported in the wild, and no patches have been published yet. Given the nature of the vulnerability, attackers could craft files that, when opened by users of affected versions, trigger the out-of-bounds write and gain control over the affected system at user privilege level.

For European organizations, the impact of CVE-2025-47108 can be significant, especially in industries relying on digital content creation, design, and media production where Adobe Substance3D - Painter is used. Successful exploitation could lead to unauthorized access to sensitive design files, intellectual property theft, and potential lateral movement within corporate networks. Since the vulnerability allows arbitrary code execution at the user level, attackers could deploy ransomware, spyware, or other malware, disrupting business operations and causing financial and reputational damage. The requirement for user interaction (opening a malicious file) means phishing or social engineering campaigns could be vectors for exploitation. Organizations with remote or hybrid workforces may face increased risk due to file sharing and email attachments. Furthermore, the high confidentiality, integrity, and availability impacts mean that critical projects and data could be compromised or destroyed, affecting compliance with European data protection regulations such as GDPR.

To mitigate this vulnerability, European organizations should: 1) Immediately inventory and identify all installations of Adobe Substance3D - Painter, focusing on versions 11.0.1 and earlier. 2) Restrict or disable the opening of untrusted or unsolicited files within the application, especially from email attachments or external sources. 3) Implement strict email filtering and phishing awareness training to reduce the risk of malicious file delivery and user interaction. 4) Employ application whitelisting and sandboxing techniques to limit the execution scope of Adobe Substance3D - Painter and contain potential exploitation. 5) Monitor for unusual application behavior or crashes that could indicate exploitation attempts. 6) Maintain up-to-date backups of critical design data to enable recovery in case of compromise. 7) Stay alert for official patches or updates from Adobe and apply them promptly once available. 8) Consider network segmentation to isolate systems running Substance3D - Painter from sensitive environments. These targeted measures go beyond generic advice by focusing on controlling file handling, user behavior, and application execution context specific to this vulnerability.
