A design flaw in all versions of Go-Ethereum allows an attacker node to send 5120 pending transactions of a high gas price from one account that all fully spend the full balance of the account to a victim Geth node, which can purge all of pending transactions in a victim nodes memory pool and then occupy the memory pool to prevent new transactions from entering the pool, resulting in a denial of service (DoS).

Weakness

The product does not properly control the allocation and maintenance of a limited resource.

Potential Mitigations

  • Mitigation of resource exhaustion attacks requires that the target system either:

  • The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.

  • The second solution is simply difficult to effectively institute – and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
