Descriptions
A vulnerability in the Cisco Aironet Series Access Points (APs) software could allow an authenticated, adjacent attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to a deadlock condition that may occur when an affected AP attempts to dequeue aggregated traffic that is destined to an attacker-controlled wireless client. An attacker who can successfully transition between multiple Service Set Identifiers (SSIDs) hosted on the same AP while replicating the required traffic patterns could trigger the deadlock condition. A watchdog timer that detects the condition will trigger a reload of the device, resulting in a DoS condition while the device restarts.
Una vulnerabilidad en el software de Cisco Aironet Series Access Points (APs) podría permitir que un atacante autenticado adyacente haga que el dispositivo afectado se reinicie inesperadamente y provoque una denegación de servicio (DoS) como consecuencia. La vulnerabilidad se debe a una condición deadlock que podría ocurrir cuando un AP afectado intenta quitar de la cola el tráfico agregado que está destinado a un cliente inalámbrico controlado por el atacante. Un atacante que pueda moverse exitosamente entre múltiples SSID (Service Set Identifiers) alojados en el mismo AP al replicar los patrones de tráfico requeridos podría desencadenar la condición deadlock. Un temporizador "watchdog" que detecte esta condición desencadenará la recarga del dispositivo, lo que resulta en una condición de denegación de servicio (DoS) mientras se reinicia el dispositivo.
