RIP Poisoning Routing Table Modification (Adjacent Network)
Medium Nessus Plugin ID 39587
SynopsisRouting tables can be modified.
DescriptionIt was possible to poison the remote host routing tables through the RIP protocol.
An attacker may use this to hijack network connections.
Several RIP agents reject routes that are not sent by a neighbor, so this flaw may not be exploitable from a non-adjacent network.
SolutionEither disable the RIP listener if it is not used, use RIP-2 in conjunction with authentication, or use another routing protocol.
