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 when the software parses specially crafted files, leading to a read operation beyond the allocated memory buffer. This memory corruption can be leveraged by an attacker to execute arbitrary code within the context of the current user, potentially compromising system confidentiality, integrity, and availability. Exploitation requires user interaction, specifically the victim opening a maliciously crafted file, which makes social engineering or phishing a likely attack vector. The CVSS v3.1 score of 7.8 reflects high severity due to the high impact on confidentiality, integrity, and availability, combined with low attack complexity and no privileges required. Although no known exploits have been reported in the wild, the vulnerability poses a significant risk to users of Substance3D - Stager, a tool widely used in 3D design and digital content creation. The absence of publicly available patches at the time of disclosure necessitates immediate defensive measures to reduce exposure. The vulnerability's exploitation could allow attackers to gain code execution capabilities, potentially leading to further compromise of enterprise environments where the software is deployed.

For European organizations, the impact of CVE-2025-61805 can be substantial, especially for those in industries relying heavily on Adobe Substance3D - Stager, such as digital media, gaming, advertising, and product design. Successful exploitation could lead to unauthorized access to sensitive design files, intellectual property theft, and disruption of creative workflows. The ability to execute arbitrary code elevates the risk of lateral movement within networks, data exfiltration, or deployment of ransomware. Given the requirement for user interaction, phishing campaigns or malicious file distribution could be effective attack vectors. The high confidentiality, integrity, and availability impacts mean that affected organizations could suffer significant operational and reputational damage. Additionally, organizations with regulatory obligations under GDPR may face compliance risks if personal data is exposed or systems are compromised. The lack of known exploits in the wild currently provides a window for proactive defense, but the high severity score indicates urgency in addressing the vulnerability.

1. Immediately restrict the opening of untrusted or unsolicited files in Adobe Substance3D - Stager by implementing strict file source controls and user policies. 2. Educate users on the risks of opening files from unknown or unverified sources, emphasizing the potential for malicious crafted files. 3. Monitor and audit file access and application behavior for anomalies indicative of exploitation attempts, such as unexpected crashes or unusual process activity. 4. Employ application whitelisting and sandboxing techniques to limit the impact of potential code execution within Substance3D - Stager. 5. Coordinate with Adobe for timely patch deployment once available; in the interim, consider disabling or limiting the use of Substance3D - Stager in high-risk environments. 6. Integrate endpoint detection and response (EDR) solutions to detect exploitation patterns and respond rapidly to incidents. 7. Review and enhance email and file transfer security controls to reduce the likelihood of malicious files reaching end users. 8. Implement network segmentation to contain potential breaches originating from compromised workstations running the vulnerable software.
