Descriptions
A vulnerability in the web services interface of Cisco Adaptive Security Appliance (ASA) and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to upload arbitrary-sized files to specific folders on an affected device, which could lead to an unexpected device reload. The vulnerability exists because the affected software does not efficiently handle the writing of large files to specific folders on the local file system. An attacker could exploit this vulnerability by uploading files to those specific folders. A successful exploit could allow the attacker to write a file that triggers a watchdog timeout, which would cause the device to unexpectedly reload, causing a denial of service (DoS) condition.
Una vulnerabilidad en la interfaz de servicios web de Cisco Adaptive Security Appliance (ASA) y Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado cargar archivos de tamaño arbitrario en carpetas específicas en un dispositivo afectado, que podría conllevar a una recarga inesperada del dispositivo. La vulnerabilidad se presenta porque el software afectado no maneja de manera eficiente la escritura de archivos de gran tamaño en carpetas específicas en el sistema de archivos local. Un atacante podría explotar esta vulnerabilidad mediante la carga de archivos en esas carpetas específicas. Una explotación con éxito podría permitir a un atacante escribir un archivo que desencadena un tiempo de espera del watchdog, lo que causaría la recarga inesperada del dispositivo, causando una condición de denegación de servicio (DoS)
