The P2P protocols lack of rate limit. For example, in relay protocol, when a node receives a broadcasted tx_hashes, it will mark it in memory to avoid duplicated requests. code → .
It is easy to establish a DoS attach by generating random tx hashes.
Impact
It affects all nodes connected to the P2P network.
Workarounds
Apply rate limit on the data sent to CKB P2P port.
