Descriptions

A vulnerability in the sfmgr daemon of Cisco Firepower Management Center (FMC) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to perform directory traversal and access directories outside the restricted path. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by using a relative path in specific sfmgr commands. An exploit could allow the attacker to read or write arbitrary files on an sftunnel-connected peer device.

Una vulnerabilidad en el demonio sfmgr de Cisco Firepower Management Center (FMC) Software y Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto autenticado llevar a cabo un salto de directorio y acceder a directorios fuera de la ruta restringida. La vulnerabilidad es debido a una comprobación insuficiente de la entrada. Un atacante podría explotar esta vulnerabilidad mediante el uso de una ruta relativa en comandos sfmgr específicos. Una explotación podría permitir a un atacante leer o escribir archivos arbitrarios en un dispositivo peer conectado a sftunnel
