      "value": "Reolink desktop application 8.18.12 contains a vulnerability in its local authentication mechanism. The application implements lock screen password logic entirely on the client side using JavaScript within an Electron resource file. Because the password is stored and returned via a modifiable JavaScript property(a.settingsManager.lockScreenPassword), an attacker can patch the return value to bypass authentication. NOTE: this is disputed by the Supplier because the lock-screen bypass would only occur if the local user modified his own instance of the application."

      "value": "La aplicación de escritorio Reolink 8.18.12 contiene una vulnerabilidad en su mecanismo de autenticación local. La aplicación implementa la lógica de contraseña de la pantalla de bloqueo completamente en el lado del cliente usando JavaScript dentro de un archivo de recursos de Electron. Debido a que la contraseña se almacena y se devuelve a través de una propiedad JavaScript modificable (a.settingsManager.lockScreenPassword), un atacante puede parchear el valor de retorno para omitir la autenticación. NOTA: esto es disputado por el Proveedor porque la omisión de la pantalla de bloqueo solo ocurriría si el usuario local modificara su propia instancia de la aplicación."
