Summary
A vulnerability in the Secure Copy Protocol (SCP) and SFTP feature of Cisco IOS XR Software could allow an authenticated, local attacker to create or overwrite files in a system directory, which could lead to a denial of service (DoS) condition. The attacker would require valid user credentials to perform this attack.
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.
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.
