CVE-2019-5061

An exploitable denial-of-service vulnerability exists in the hostapd 2.6, where an attacker could trigger AP to send IAPP location updates for stations, before the required authentication process has completed. This could lead to different denial of service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby Aps of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.

Se presenta una vulnerabilidad de denegación de servicio explotable en el hostapd versión 2.6, donde un atacante podría activar AP para enviar actualizaciones de ubicación IAPP para las estaciones, antes de que el proceso de autenticación requerido se complete . Esto podría conllevar a diferentes escenarios de denegación de servicio, ya sea causando ataques a la tabla CAM o conllevando un aleteo de tráfico si falsifica clientes existentes en otros Aps cercanos de la misma infraestructura inalámbrica. Un atacante puede falsificar paquetes de petición de Autenticación y Asociación para activar esta vulnerabilidad.
