Executive brief
Adobe Substance 3D Designer, a professional tool for creating 3D materials and textures, is affected by a security flaw that could allow an attacker to take control of a user's computer. To exploit this, an attacker would need to trick a user into opening a specially crafted malicious file. Successful exploitation could lead to unauthorized access to sensitive data or the disruption of business operations.
Technical details
An out-of-bounds write vulnerability (CWE-787) exists in Adobe Substance 3D Designer versions 15.1.0 and earlier. The flaw is triggered when the application processes a specially crafted file, leading to memory corruption. An attacker can leverage this to execute arbitrary code in the context of the current user. Exploitation requires local access and user interaction, specifically the opening of a malicious file. Adobe has addressed this issue in later versions, and users are advised to update to the latest available release.
