Descriptions

Amazon AWS SDK <=2.8.5 for Android uses Android SharedPreferences to store plain text AWS STS Temporary Credentials retrieved by AWS Cognito Identity Service. An attacker can use these credentials to create authenticated and/or authorized requests. Note that the attacker must have "root" privilege access to the Android filesystem in order to exploit this vulnerability (i.e. the device has been compromised, such as disabling or bypassing Android's fundamental security mechanisms).

Amazon AWS SDK, en versiones 2.8.5 y anteriores, utiliza la clase "Android SharedPreferences" para almacenar las credenciales temporales de AWS STS recuperadas por AWS Cognito Identity Service. Un atacante puede utilizar estas credenciales para crear peticiones autenticadas y/o autorizadas. Nótese que el atacante deberá tener acceso de privilegios root en sistema de archivos de Android para poder explotar esta vulnerabilidad; es decir, el dispositivo se ha comprometido, por ejemplo, deshabilitando u omitiendo los mecanismos fundamentales de seguridad de Android.
