Descriptions
A vulnerability in the multicast DNS (mDNS) gateway feature of Cisco IOS XE Software for Wireless LAN Controllers (WLCs) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition.
This vulnerability is due to improper management of mDNS client entries. An attacker could exploit this vulnerability by connecting to the wireless network and sending a continuous stream of specific mDNS packets. A successful exploit could allow the attacker to cause the wireless controller to have high CPU utilization, which could lead to access points (APs) losing their connection to the controller and result in a DoS condition.
Una vulnerabilidad en la función de puerta de enlace DNS de multidifusión (mDNS) del software Cisco IOS XE para controladores de LAN inalámbrica (WLC) podría permitir que un atacante adyacente no autenticado provoque una condición de denegación de servicio (DoS). Esta vulnerabilidad se debe a una gestión inadecuada de las entradas del cliente mDNS. Un atacante podría aprovechar esta vulnerabilidad conectándose a la red inalámbrica y enviando un flujo continuo de paquetes mDNS específicos. Un exploit exitoso podría permitir que el atacante haga que el controlador inalámbrico tenga una alta utilización de la CPU, lo que podría llevar a que los puntos de acceso (AP) pierdan su conexión con el controlador y resulte en una condición DoS.
