The vulnerability is due to how the SMB protocol handles a case in which a large file transfer fails. This case occurs when some pieces of the file are successfully transferred to the remote endpoint, but ultimately the file transfer fails and is reset. An attacker could exploit this vulnerability by sending a crafted SMB file transfer request through the targeted device. An exploit could allow the attacker to pass an SMB file that contains malware, which the device is configured to block. This vulnerability affects Cisco Firepower System Software when one or more file action policies are configured, on software releases prior to 6.2.3.

La vulnerabilidad se debe a c\u00f3mo el protocolo SMB gestiona un caso en el que fracasa una transferencia de un archivo grande. Este caso ocurre cuando algunas partes del archivo se transfieren con \u00e9xito al endpoint remoto pero, en \u00faltima instancia, la transferencia fracasa y se reinicia. Un atacante podr\u00eda explotar esta vulnerabilidad mediante el env\u00edo de una petici\u00f3n de transferencia de SMB manipulada al dispositivo objetivo. Su explotaci\u00f3n podr\u00eda permitir que el atacante pase un archivo SMB que contiene malware, que el dispositivo debe bloquear.
