Abstract:

We present new OSPF attacks that exploit design vulnerabilities in the protocol specification. These new attacks can affect the Link State Advertisements (LSA) of routers not controlled by the attacker while evading the OSPF “fight-back” mechanism. As a result, an attacker can persistently control the routing tables of routers it does not control, thereby enabling the attacker to eavesdrop and modify traffic.
