Descriptions
A vulnerability in the handling of Inter-Access Point Protocol (IAPP) messages by Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. The vulnerability exist because the software improperly validates input on fields within IAPP messages. An attacker could exploit the vulnerability by sending malicious IAPP messages to an affected device. A successful exploit could allow the attacker to cause the Cisco WLC Software to reload, resulting in a DoS condition. Software versions prior to 8.2.170.0, 8.5.150.0, and 8.8.100.0 are affected.
Una vulnerabilidad en el manejo de mensajes de Protocolo Inter-Access Point (IAPP) para el software Wireless LAN Controller (WLC) de Cisco, podría permitir que un atacante no identificado, adyacente causa una condición de denegación de servicio (DoS). La vulnerabilidad existe porque el software comprueba incorrectamente la entrada en los campos dentro de los mensajes IAPP. Un atacante podría aprovechar la vulnerabilidad enviando mensajes IAPP maliciosos a un dispositivo afectado. Una operación con éxito podría permitir que el atacante hiciera que el software WLC de Cisco se recargue, resultando en una condición DoS. Las versiones de software anteriores a 8.2.170.0, 8.5.150.0 y 8.8.100.0 se ven afectadas.
