Technical details
The broadcast_and_verify function fails to validate whether the client-supplied gas_limit is sufficient before broadcasting a transaction. When wait_for_confirmation is true (default), no simulation occurs; when false, simulation omits the gas parameter and misses out-of-gas conditions. An unauthenticated remote attacker can craft transactions with insufficient gas, forcing the fee-payer server to absorb the consumed gas cost while the transaction reverts, enabling a zero-cost denial-of-service attack.
Affected products
- ZenHive mpp 0.4.0
