Executive brief
Adobe Substance 3D Painter, a professional 3D texturing and painting application, is affected by a security flaw that could allow an attacker to take control of a user's computer. To exploit this, an attacker must trick a user into opening a specially crafted malicious file. Successful exploitation could lead to unauthorized software execution, data theft, or complete system compromise in the context of the logged-in user.
Technical details
An out-of-bounds write vulnerability (CWE-787) exists in Adobe Substance 3D Painter versions 12.0.2 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 with the privileges of the current user. Exploitation requires local delivery of a malicious file and user interaction (opening the file). Adobe has addressed this in version 12.0.3.
