Descriptions

A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol component of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to retrieve memory contents, which could lead to the disclosure of confidential information. The vulnerability is due to insufficient condition checks in the part of the code that handles CAPWAP keepalive requests. An attacker could exploit this vulnerability by sending a crafted CAPWAP keepalive packet to a vulnerable Cisco WLC device. A successful exploit could allow the attacker to retrieve the contents of device memory, which could lead to the disclosure of confidential information.

Una vulnerabilidad en el componente del protocolo CAPWAP (Control and Provisioning of Wireless Access Points) de Cisco Wireless LAN Controller (WLC) Software podría permitir que un atacante remoto no autenticado recupere el contenido de la memoria, lo que podría conducir a la divulgación de información confidencial. La vulnerabilidad se debe a comprobaciones de condición insuficientes en la parte del código que gestiona las peticiones CAPWAP keepalive. Un atacante podría explotar esta vulnerabilidad enviando un paquete CAPWAP keepalive manipulado a un dispositivo Cisco WLC vulnerable. Su explotación con éxito podría permitir que el atacante recupere el contenido de la memoria del dispositivo, lo que podría conducir a la divulgación de información confidencial.
