Descriptions

A Denial of Service (Dos) vulnerability in Nozomi Networks Guardian, caused by improper input validation in certain fields used in the Radius parsing functionality of our IDS, allows an unauthenticated attacker sending specially crafted malformed network packets to cause the IDS module to stop updating nodes, links, and assets.



Network traffic may not be analyzed until the IDS module is restarted.

Una vulnerabilidad de denegación de servicio (DOS) en Nozomi Networks Guardian, causada por una validación de entrada incorrecta en ciertos campos utilizados en la funcionalidad de análisis Radius de nuestro IDS, permite que un atacante no autenticado envíe paquetes de red mal formados especialmente manipulados para provocar que el módulo IDS deje de actualizar los nodos, enlaces y activos. Es posible que el tráfico de red no se analice hasta que se reinicie el módulo IDS.
