The attacker would require valid user credentials to perform this attack.\r\n\r This vulnerability is due to a lack of proper validation of SCP and SFTP CLI input parameters. An attacker could exploit this vulnerability by authenticating to the device and issuing SCP or SFTP CLI commands with specific parameters. A successful exploit could allow the attacker to impact the functionality of the device, which could lead to a DoS condition. The device may need to be manually rebooted to recover.\r\n\r Note: This vulnerability is exploitable only when a local user invokes SCP or SFTP commands at the Cisco IOS XR CLI. A local user with administrative privileges could exploit this vulnerability remotely."}, {"lang": "es", "value": "Una vulnerabilidad en Secure Copy Protocol (SCP) y la funci\u00f3n SFTP del software Cisco IOS XR podr\u00eda permitir que un atacante local autenticado cree o sobrescriba archivos en un directorio del sistema, lo que podr\u00eda provocar una condici\u00f3n de denegaci\u00f3n de servicio (DoS). El atacante requerir\u00eda credenciales de usuario v\u00e1lidas para realizar este ataque.
