CVE-2025-61833 is an out-of-bounds read vulnerability classified under CWE-125 affecting Adobe Substance3D - Stager versions 3.1.5 and earlier. The flaw arises during the parsing of crafted files, where the software reads beyond the allocated memory buffer, potentially exposing sensitive data or corrupting memory. This memory corruption can be leveraged by attackers to execute arbitrary code within the context of the current user, thereby compromising system integrity and confidentiality. Exploitation requires user interaction, specifically the victim opening a maliciously crafted file, which suggests a vector through phishing or social engineering. The vulnerability has a CVSS 3.1 base score of 7.8, indicating 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). No patches or known exploits are currently available, highlighting the importance of proactive mitigation. Adobe Substance3D - Stager is widely used in digital content creation, making this vulnerability relevant to organizations relying on this software for 3D design and visualization workflows.

For European organizations, especially those in creative industries such as gaming, animation, advertising, and industrial design, this vulnerability poses a significant risk. Exploitation could lead to unauthorized code execution, data leakage, or disruption of critical design workflows, potentially causing intellectual property theft or operational downtime. Since the attack requires user interaction, phishing campaigns targeting employees could be an effective delivery method. The compromise of design workstations could also serve as a foothold for lateral movement within corporate networks, escalating the threat to broader enterprise systems. The high impact on confidentiality, integrity, and availability underscores the potential for severe business disruption and reputational damage. Organizations handling sensitive client projects or proprietary designs are particularly vulnerable to exploitation consequences.

Organizations should immediately verify the version of Adobe Substance3D - Stager in use and upgrade to the latest version once Adobe releases a patch addressing CVE-2025-61833. Until a patch is available, implement strict file handling policies, including disabling or restricting the opening of untrusted or unsolicited files in Substance3D - Stager. Employ endpoint security solutions capable of detecting anomalous behavior related to file parsing or memory corruption. Conduct user awareness training focused on recognizing phishing attempts that could deliver malicious files. Network segmentation of design workstations can limit lateral movement if a compromise occurs. Additionally, monitor logs and system behavior for signs of exploitation attempts. Collaborate with Adobe support channels for updates and advisories. Finally, consider application whitelisting and sandboxing techniques to contain potential exploits.
