| Title: | Cisco Smart Install (SMI) Protocol Misuse (cisco-sa-20170214-smi) - Unreliable Check |
| Summary: | Several researchers have reported on the use of Smart Install; (SMI) protocol messages toward Smart Install clients, also known as integrated branch clients; (IBC), allowing an unauthenticated, remote attacker to change the startup-config file and force a; reload of the device, load a new IOS image on the device, and execute high-privilege CLI commands; on switches running Cisco IOS and IOS XE Software.;; Cisco does not consider this a vulnerability in Cisco IOS, IOS XE, or the Smart Install feature; itself but a misuse of the Smart Install protocol, which does not require authentication by; design. Customers who are seeking more than zero-touch deployment should consider deploying the; Cisco Network Plug and Play solution instead. |
| Description: | Summary: Several researchers have reported on the use of Smart Install (SMI) protocol messages toward Smart Install clients, also known as integrated branch clients (IBC), allowing an unauthenticated, remote attacker to change the startup-config file and force a reload of the device, load a new IOS image on the device, and execute high-privilege CLI commands on switches running Cisco IOS and IOS XE Software. Cisco does not consider this a vulnerability in Cisco IOS, IOS XE, or the Smart Install feature itself but a misuse of the Smart Install protocol, which does not require authentication by design. Customers who are seeking more than zero-touch deployment should consider deploying the Cisco Network Plug and Play solution instead. Solution: Cisco has updated the Smart Install Configuration Guide to include security best practices regarding the deployment of the Cisco Smart Install feature within customer infrastructures.
