Wi-Fi Protected Access II (WPA2) protocolo de vulnerabilidad.

Los investigadores Mathy Vanhoef y Frank Piessens de la Universidad de Leuven descubrieron vulnerabilidades de seguridad en las negociaciones claves en los protocolos Wi-Fi Protected Access (WPA) y Wi-Fi Protected Access II (WPA2). Un atacante dentro del alcance de un punto de acceso inalámbrico afectado (AP) y el cliente pueden aprovechar estas vulnerabilidades para realizar ataques utilizando protocolos de confidencialidad de datos susceptibles. Estas vulnerabilidades podrían permitir la reinstalación de la clave temporal del grupo (GTK) durante el intercambio de claves de grupo, lo que podría permitir que un atacante dentro del rango de alcance repetir cuadros desde los puntos de acceso a los clientes.

Alcance de impacto:

Clientes de Wi-Fi con seguridad WPA o WPA2 son afectados. Esto significa que cualquier computadora con wireless puede verse afectada.
