An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected system. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected system, which could cause the system to reload, resulting in a denial of service (DoS) condition."},{"lang":"es","value":"Una vulnerabilidad en la interfaz de servicios web del software Cisco Secure Firewall Adaptive Security Appliance (ASA) y del software Cisco Secure Firewall Threat Defense (FTD) podría permitir que un atacante remoto no autenticado provoque un desbordamiento de búfer en un sistema afectado. Esta vulnerabilidad se debe a comprobaciones de los límites insuficientes para datos específicos que se proporcionan a la interfaz de servicios web de un sistema afectado. Un atacante podría explotar esta vulnerabilidad enviando una solicitud HTTP manipulada al sistema afectado.
