Descriptions

A vulnerability in the errdisable per VLAN feature of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause the device to crash, leading to a denial of service (DoS) condition. The vulnerability is due to a race condition that occurs when the VLAN and port enter an errdisabled state, resulting in an incorrect state in the software. An attacker could exploit this vulnerability by sending frames that trigger the errdisable condition. A successful exploit could allow the attacker to cause the affected device to crash, leading to a DoS condition.

Una vulnerabilidad en la característica errdisable per VLAN en Cisco IOS XE Software podría permitir que un atacante adyacente sin autenticar haga que el dispositivo se cierre inesperadamente, provocando una denegación de servicio (DoS). La vulnerabilidad se debe a una condición de carrera que ocurre cuando VLAN y el puerto entran en estado errdisabled, lo que resulta en un estado incorrecto en el software. Un atacante podría explotar esta vulnerabilidad enviando frames que desencadenan la condición errdisabled. Si se explota con éxito, podría permitir que el atacante consiga que el dispositivo afectado se cierre inesperadamente, provocando una denegación de servicio (DoS).
