Descriptions

A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) Discovery Request parsing functionality of Cisco Wireless LAN Controllers could allow an unauthenticated, remote attacker to cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to incomplete input validation of fields in CAPWAP Discovery Request packets by the affected device. An attacker could exploit this vulnerability by sending crafted CAPWAP Discovery Request packets to an affected device. A successful exploit could allow the attacker to cause the affected device to restart unexpectedly, resulting in a DoS condition. Cisco Bug IDs: CSCvb95842.

Una vulnerabilidad en la funcionalidad de análisis sintáctico de Control and Provisioning of Wireless Access Points (CAPWAP) Discovery Request podría permitir que un atacante remoto sin autenticar provoque que el dispositivo afectado se reinicie de manera inesperada, resultando en una denegación de servicio (DoS). Esta vulnerabilidad se debe a la validación incompleta de los valores de entrada de los campos en los paquetes CAPWAP Discovery Request por parte del dispositivo afectado. Un atacante podría explotar esta vulnerabilidad enviando paquetes CAPWAP Discovery Request manipulados al dispositivo afectado. Si se explota con éxito, podría permitir que el atacante consiga que el dispositivo afectado se reinicie de manera inesperada, provocando una denegación de servicio. Cisco Bug IDs: CSCvb95842.
