Cisco Smart Install Detection

info Nessus Plugin ID 105161
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The Cisco Smart Install feature is enabled on the remote host.


The Cisco Smart Install (SMI) feature is enabled on the remote host.
If the SMI Client role enabled, it is subject to protocol misuse, which could allow an unauthenticated, remote attacker to:

- Substitute the switch's startup-config file with a file that the attacker prepared and force a reload of the switch after a defined time interval.

- Load the attacker-supplied IOS image onto the switch.

- Execute high-privilege configuration mode CLI commands on the switch, including do-exec CLI commands.

- Copy arbitrary files from the switch to the attacker-controlled TFTP server.


Disable the Smart Install feature if not needed.
