CVE-2025-61805 is an out-of-bounds read vulnerability classified under CWE-125 affecting Adobe Substance3D - Stager versions 3.1.4 and earlier. The vulnerability arises during the parsing of specially crafted files, where the software reads beyond the allocated memory buffer. This memory corruption can be exploited by an attacker to execute arbitrary code within the context of the current user. The attack vector requires local user interaction, specifically the victim opening a malicious file, which makes social engineering or phishing a likely exploitation method. The vulnerability impacts confidentiality, integrity, and availability, as arbitrary code execution can lead to data theft, system compromise, or denial of service. The CVSS v3.1 score of 7.8 reflects a high severity, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Currently, no public exploits are known, but the presence of this vulnerability in a widely used creative software suite poses a significant risk. Adobe has not yet released patches, so users must rely on mitigations until updates are available.

For European organizations, especially those in digital content creation, media, and design sectors that rely on Adobe Substance3D - Stager, this vulnerability could lead to severe consequences. Exploitation could allow attackers to execute arbitrary code, potentially leading to data breaches, intellectual property theft, or disruption of creative workflows. Since the vulnerability requires user interaction, targeted phishing campaigns or malicious file distribution could be effective attack vectors. The compromise of workstations could also serve as a foothold for lateral movement within corporate networks, escalating risks to broader IT infrastructure. Confidentiality of sensitive design files and proprietary assets is at risk, as is the integrity of the creative output. Availability may also be impacted if attackers deploy destructive payloads or ransomware. The lack of known exploits currently reduces immediate risk but does not eliminate the threat, especially as threat actors may develop exploits rapidly once the vulnerability is public.

Organizations should implement a multi-layered defense approach. First, restrict the opening of files from untrusted or unknown sources, especially unsolicited files received via email or downloads. Employ robust endpoint protection solutions capable of detecting anomalous behavior related to memory corruption exploits. Enable application whitelisting and sandboxing where possible to limit the impact of malicious files. Monitor user activity and network traffic for signs of exploitation attempts. Educate users about the risks of opening files from unknown sources and train them to recognize phishing attempts. Since no patches are currently available, consider isolating systems running Adobe Substance3D - Stager from critical networks until updates are released. Once Adobe issues a patch, prioritize timely deployment. Additionally, maintain regular backups of critical data to mitigate potential ransomware or destructive attacks stemming from exploitation.
