CVE-2025-61807 identifies an integer overflow or wraparound vulnerability (CWE-190) in Adobe Substance3D - Stager, a 3D design and staging application widely used in digital content creation. The vulnerability exists in versions 3.1.4 and earlier, where improper handling of integer values during file processing can cause an overflow condition. This overflow can lead to memory corruption, enabling an attacker to execute arbitrary code within the context of the current user. Exploitation requires a victim to open a maliciously crafted file, making user interaction mandatory. The CVSS v3.1 base score is 7.8, reflecting high severity with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), and user interaction required (UI:R). The impact includes full compromise of confidentiality, integrity, and availability of the affected system. No patches or known exploits have been reported at the time of publication, but the vulnerability is publicly disclosed and should be treated with urgency. The flaw is particularly concerning for environments where Adobe Substance3D - Stager is used to process untrusted files or where users may be targeted with social engineering attacks to open malicious content.

For European organizations, the impact of CVE-2025-61807 can be significant, especially in sectors relying on Adobe Substance3D - Stager for digital content creation, such as media, advertising, gaming, and industrial design. Successful exploitation could lead to arbitrary code execution, allowing attackers to steal sensitive intellectual property, deploy malware, or move laterally within networks. Given the local attack vector and requirement for user interaction, phishing or social engineering campaigns could be leveraged to deliver malicious files. The compromise of design assets or proprietary models could result in financial loss, reputational damage, and intellectual property theft. Additionally, disruption of creative workflows could impact business continuity. The vulnerability’s high severity and potential for full system compromise necessitate immediate attention to prevent exploitation in European organizations.

1. Immediately restrict the opening of files from untrusted or unknown sources within Adobe Substance3D - Stager environments. 2. Implement strict email and file filtering to block or quarantine suspicious attachments that could exploit this vulnerability. 3. Employ application whitelisting and sandboxing techniques to limit the execution scope of Substance3D - Stager and contain potential exploits. 4. Educate users on the risks of opening unsolicited or unexpected files, emphasizing caution with files received via email or external sources. 5. Monitor system and application logs for unusual behavior indicative of exploitation attempts, such as crashes or unexpected process activity. 6. Coordinate with Adobe for timely patch releases and apply updates as soon as they become available. 7. Consider deploying endpoint detection and response (EDR) solutions capable of detecting exploitation patterns related to integer overflow vulnerabilities. 8. Maintain regular backups of critical design data to enable recovery in case of compromise.
