This attack is mainly because the keeper of the EthCrossChainData contract can be modified by the EthCrossChainManager contract, and the verifyHeaderAndExecuteTx function of the EthCrossChainManager contract can execute the data passed in by the user through ...
the _executeCrossChainTx function. Therefore, the attacker uses this function to pass in carefully constructed data to modify the keeper of the EthCrossChainData contract. It is not the case that this event occurred due to the leakage of the keeper's private key.
