CVE-2025-30322 is a high-severity out-of-bounds write vulnerability (CWE-787) affecting Adobe Substance3D - Painter versions 11.0 and earlier. This vulnerability arises when the software improperly handles memory boundaries, allowing an attacker to write data outside the intended buffer limits. Such an out-of-bounds write can corrupt memory, potentially enabling arbitrary code execution within the context of the current user. Exploitation requires user interaction, specifically that the victim opens a crafted malicious 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 code, escalate privileges, or disrupt application functionality. No known exploits are currently reported in the wild, and no patches have been linked yet. Adobe Substance3D - Painter is a professional 3D painting software widely used in digital content creation, including industries such as gaming, film, and design. The vulnerability's exploitation vector through malicious files suggests that threat actors could distribute weaponized assets via email, shared projects, or compromised repositories to target users.

For European organizations, particularly those in creative industries, digital media, gaming, and design sectors, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized code execution, data breaches, or disruption of critical creative workflows. Since the vulnerability executes code with the current user's privileges, the impact depends on the user's access level; however, it could facilitate lateral movement or further compromise if the user has elevated rights. The requirement for user interaction means social engineering or phishing campaigns could be leveraged to deliver malicious files. Organizations relying on Adobe Substance3D - Painter for content creation may face operational downtime, intellectual property theft, or reputational damage if exploited. Additionally, the high confidentiality impact could expose sensitive design assets or proprietary information. The absence of known exploits currently provides a window for proactive mitigation before active attacks emerge.

European organizations should implement targeted mitigations beyond generic advice: 1) Restrict usage of Adobe Substance3D - Painter to trusted users and environments, limiting exposure. 2) Educate users on the risks of opening files from untrusted sources, emphasizing verification of file origins. 3) Employ application whitelisting and sandboxing techniques to contain potential exploitation within isolated environments. 4) Monitor network and endpoint logs for unusual activity related to Substance3D - Painter processes or file access patterns. 5) Coordinate with Adobe for timely patch deployment once available, and subscribe to official security advisories. 6) Implement strict access controls and least privilege principles for users operating the software to minimize impact scope. 7) Use advanced email filtering and endpoint protection solutions capable of detecting malicious payloads embedded in files. 8) Maintain regular backups of critical project files to enable recovery in case of compromise.
