Targeted transaction denial via erroneous nonce increment
Published Jul 13, 2023 · Updated Oct 22, 2024
Transaction-processing error in MultiversX mx-chain-go before 1.4.17 allows remote attackers to block a targeted account's transactions. Relayed transaction processing increments the inner sender account's nonce even when the inner transaction fails validation. An attacker able to submit repeated relayed transactions can advance the target's expected nonce, preventing ordinary transactions until the paid attack stops.
