The application loads certain dynamic-link library (DLL) dependencies using the default Windows search order, which includes directories that may be writable by non-privileged users.\\n\\n\\n\\nBecause these directories can be modified by unprivileged users, an attacker can place a malicious DLL with the same name as a legitimate dependency in a directory that is searched before trusted system locations. When the application is executed, which is always with administrative privileges, the malicious DLL is loaded instead of the legitimate library.\\n\\n\\n\\nThe application does not enforce restrictions on DLL loading locations and does not verify the integrity or digital signature of loaded libraries. As a result, attacker-controlled code may be executed within the security context of the application, allowing arbitrary code execution with elevated privileges.\\n\\n\\n\\nSuccessful exploitation requires that an attacker place a crafted malicious DLL in a user-writable directory that is included in the application's DLL search path and then cause the affected application to be executed. Once loaded, the malicious DLL runs with the same privileges as the application.\\n\\n\\n\\nThis issue affects\u00a0\\nTR-VISION HOME\u00a0\u00a0versions up to and including 2.0.5."}, {"lang": "es", "value": "Una vulnerabilidad de secuestro del orden de b\u00fasqueda de DLL en Thermalright TR-VISION HOME en Windows (64 bits) permite a un atacante local escalar privilegios mediante la carga lateral de DLL.
