Description
Bootp is a user datagram protocol (UDP) that can be used by Cisco routers to access copies of Cisco IOS Software on another Cisco router running the Bootp service. In this scenario, one Cisco router acts as a Cisco IOS Software server that can download the software to other Cisco routers acting as Bootp clients. In reality, this service is rarely used and can allow an attacker to download a copy of a router’s Cisco IOS Software.
