CVE-2025-20202

A vulnerability in Cisco IOS XE Wireless Controller Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of access point (AP) Cisco Discovery Protocol (CDP) neighbor reports when they are processed by the wireless controller. An attacker could exploit this vulnerability by sending a crafted CDP packet to an AP. A successful exploit could allow the attacker to cause an unexpected reload of the wireless controller that is managing the AP, resulting in a DoS condition that affects the wireless network.

Una vulnerabilidad en Cisco IOS XE Wireless Controller Software podría permitir que un atacante adyacente no autenticado provoque una denegación de servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad se debe a una validación insuficiente de los informes de vecino del Protocolo de Descubrimiento de Cisco (CDP) del punto de acceso (AP) cuando son procesados por el controlador inalámbrico. Un atacante podría explotar esta vulnerabilidad enviando un paquete CDP manipulado a un AP. Una explotación exitosa podría permitir al atacante provocar una recarga inesperada del controlador inalámbrico que administra el AP, lo que resultaría en una denegación de servicio (DoS) que afectaría a la red inalámbrica.
