CVE-2021-1615

A vulnerability in the packet processing functionality of Cisco Embedded Wireless Controller (EWC) Software for Catalyst Access Points (APs) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected AP. This vulnerability is due to insufficient buffer allocation. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to exhaust available resources and cause a DoS condition on an affected AP, as well as a DoS condition for client traffic traversing the AP.

Una vulnerabilidad en la funcionalidad packet processing de Cisco Embedded Wireless Controller (EWC) Software for Catalyst Access Points (APs) podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un AP afectado. Esta vulnerabilidad es debido a una asignación insuficiente del búfer. Un atacante podría explotar esta vulnerabilidad mediante el envío de tráfico diseñado a un dispositivo afectado. Una explotación con éxito podría permitir al atacante agotar los recursos disponibles y causar una condición de DoS en un AP afectado, así como una condición de DoS para el tráfico del cliente que atraviesa el AP
