Descriptions

RouterOS versions 6.45.6 Stable, 6.44.5 Long-term, and below allow remote unauthenticated attackers to trigger DNS queries via port 8291. The queries are sent from the router to a server of the attacker's choice. The DNS responses are cached by the router, potentially resulting in cache poisoning

RouterOS versión 6.45.6 Stable, RouterOS versión 6.44.5 Long-Term y anteriores, permiten a atacantes remotos no autenticados activar consultas DNS mediante el puerto 8291. Las consultas son enviadas desde el router hacia un servidor de elección del atacante. El router almacena en caché las respuestas DNS, resultando potencialmente en envenenamiento
