"value": "A vulnerability in Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to overwrite or append arbitrary data to system files using root-level privileges. The attacker must have administrative credentials on the device. This vulnerability is due to incomplete validation of user input for a specific CLI command. An attacker could exploit this vulnerability by authenticating to the device with administrative privileges and issuing a CLI command with crafted user parameters. A successful exploit could allow the attacker to overwrite or append arbitrary data to system files using root-level privileges."

El atacante debe tener credenciales administrativas en el dispositivo. Esta vulnerabilidad es debido a una comprobaci\u00f3n incompleta de la entrada del usuario para un comando CLI espec\u00edfico. Un atacante podr\u00eda explotar esta vulnerabilidad al autenticarse en el dispositivo con privilegios administrativos y emitiendo un comando CLI con par\u00e1metros de usuario dise\u00f1ados.
