CVE-2025-43554: Out-of-bounds Write (CWE-787) in Adobe Substance3D - Modeler
Substance3D - Modeler versions 1.21.0 and earlier are affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
AI Analysis
Technical Summary
CVE-2025-43554 is a high-severity out-of-bounds write vulnerability (CWE-787) affecting Adobe Substance3D - Modeler versions 1.21.0 and earlier. This vulnerability arises when the software improperly handles memory boundaries during processing, allowing an attacker to write data outside the allocated buffer. Such out-of-bounds writes can corrupt memory, potentially leading to arbitrary code execution within the context of the current user. Exploitation requires user interaction, specifically the opening of a maliciously crafted 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. No known exploits are currently reported in the wild, and no patches have been linked yet. Adobe Substance3D - Modeler is a 3D modeling application used primarily by creative professionals for digital content creation, including in industries such as gaming, film, and design. The vulnerability could be leveraged by attackers to execute arbitrary code, potentially leading to system compromise, data theft, or further lateral movement within a network if the compromised user has elevated privileges or access to sensitive resources.
Potential Impact
For European organizations, this vulnerability poses a significant risk especially to those in creative industries, digital media, advertising, and manufacturing sectors that utilize Adobe Substance3D - Modeler for product design and visualization. Successful exploitation could lead to unauthorized access to intellectual property, disruption of design workflows, and potential data breaches. Given the high confidentiality and integrity impact, sensitive design files and proprietary models could be exposed or altered. The requirement for user interaction means phishing or social engineering campaigns could be used to deliver malicious files. Organizations with remote or hybrid workforces may face increased risk due to file sharing and remote access to design tools. Additionally, if exploited within enterprise environments, attackers could use the foothold to escalate privileges or move laterally, impacting broader IT infrastructure.
Mitigation Recommendations
Organizations should implement the following specific mitigations: 1) Immediately inventory and identify all instances of Adobe Substance3D - Modeler in use, prioritizing those at version 1.21.0 or earlier. 2) Monitor Adobe’s official channels for patches or updates addressing CVE-2025-43554 and apply them promptly once available. 3) Until patches are released, restrict the opening of untrusted or unsolicited files within Substance3D - Modeler by enforcing strict file validation policies and user training to recognize suspicious files. 4) Employ endpoint protection solutions capable of detecting anomalous behavior related to memory corruption exploits. 5) Use application whitelisting and sandboxing techniques to limit the impact of potential exploitation. 6) Enhance email and file transfer security controls to block or flag potentially malicious attachments. 7) Conduct targeted user awareness training focusing on the risks of opening files from unknown or untrusted sources, especially for creative teams. 8) Implement network segmentation to isolate design workstations from critical infrastructure to limit lateral movement opportunities.
