CVE-2025-61807 is an integer overflow or wraparound vulnerability (CWE-190) found in Adobe Substance3D - Stager versions 3.1.4 and earlier. This vulnerability arises when the software improperly handles integer values, causing an overflow that can lead to memory corruption. An attacker can exploit this flaw by crafting a malicious file that, when opened by the user, triggers the overflow condition. This can result in arbitrary code execution within the context of the current user, potentially allowing the attacker to execute malicious payloads, manipulate data, or disrupt application functionality. The vulnerability requires user interaction—specifically, the victim must open the malicious file—and does not require prior authentication, making it accessible to remote attackers who can deliver the file via email, downloads, or other file-sharing methods. The CVSS v3.1 base score is 7.8, indicating high severity, with metrics reflecting low attack complexity, no privileges required, user interaction needed, and high impact on confidentiality, integrity, and availability. No patches or exploit code are currently publicly available, but the risk remains significant due to the potential for arbitrary code execution. Adobe Substance3D - Stager is widely used in digital content creation, making this vulnerability relevant to industries relying on 3D modeling and rendering workflows.

For European organizations, the impact of CVE-2025-61807 can be substantial, particularly for those in creative sectors such as media production, advertising, gaming, and industrial design that rely on Adobe Substance3D - Stager. Successful exploitation could lead to unauthorized code execution, resulting in data theft, intellectual property compromise, or disruption of critical design workflows. Since the vulnerability executes code with the current user's privileges, the extent of damage depends on user rights; users with administrative privileges could face complete system compromise. The requirement for user interaction means social engineering or phishing campaigns could be leveraged to deliver malicious files, increasing the risk of targeted attacks. Additionally, compromised systems could serve as footholds for lateral movement within corporate networks, threatening broader organizational security. The absence of known exploits in the wild currently limits immediate widespread impact, but the high severity score and potential for damage necessitate proactive measures. European organizations must consider the confidentiality of proprietary designs and the integrity of their production pipelines as critical assets at risk.

To mitigate CVE-2025-61807 effectively, European organizations should implement a multi-layered approach: 1) Educate users about the risks of opening files from untrusted or unknown sources, emphasizing caution with email attachments and downloads. 2) Enforce the principle of least privilege by limiting user rights, ensuring that users operate with minimal necessary permissions to reduce the impact of potential code execution. 3) Employ application whitelisting and endpoint protection solutions capable of detecting anomalous behaviors associated with exploitation attempts. 4) Monitor network and endpoint logs for suspicious activity indicative of exploitation or lateral movement. 5) Maintain strict control over file sharing and collaboration platforms to prevent distribution of malicious files internally. 6) Regularly check for and apply security updates from Adobe as soon as patches become available, and consider temporary workarounds such as disabling or restricting the use of Substance3D - Stager until patched. 7) Implement sandboxing or isolated environments for opening untrusted files to contain potential exploits. 8) Collaborate with cybersecurity teams to conduct threat hunting focused on this vulnerability and related attack vectors.
