Descriptions

The Multicast DNS (mDNS) responder in Synology DiskStation Manager (DSM) before 3.1 inadvertently responds to unicast queries with source addresses that are not link-local, which allows remote attackers to cause a denial of service (traffic amplification) or obtain potentially sensitive information via port-5353 UDP packets to the Avahi component.

El contestador Multicast DNS (mDNS) en Synology DiskStation Manager (DSM) anterior a 3.1 responde inadvertidamente a consultas unicast con las direcciones de fuentes que no son enlazadas locales, lo que permite a atacantes remotos causar una denegación de servicio (amplificación de trafico) o obtener información potencialmente sensible a través de paquetes UDP del puerto 5353 en el componente Avahi.
