A vulnerability in the CLI of Cisco IOS XE Software could allow an authenticated, local attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability exists because incorrect privileges are associated with the start maintenance command. An attacker could exploit this vulnerability by accessing the management CLI of the affected device as a low-privileged user and using the start maintenance command. A successful exploit could allow the attacker to put the device in maintenance mode, which shuts down interfaces, resulting in a denial of service (DoS) condition. In case of exploitation, a device administrator can connect to the CLI and use the stop maintenance command to restore operations.
