Descriptions
Cosmos Network Ethermint <= v0.4.0 is affected by a cross-chain transaction replay vulnerability in the EVM module. Since ethermint uses the same chainIDEpoch and signature schemes with ethereum for compatibility, a verified signature in ethereum is still valid in ethermint with the same msg content and chainIDEpoch, which enables "cross-chain transaction replay" attack.
Cosmos Network Ethermint versiones anteriores e incluyendo a v0.4.0 está afectado por una vulnerabilidad de reproducción de transacciones entre cadenas en el módulo EVM. Dado que ethermint usa los mismos esquemas de chainIDEpoch y firma con ethereum para la compatibilidad, una firma verificada en ethereum sigue siendo válida en ethermint con el mismo contenido de msg y chainIDEpoch, que permite el ataque de "cross-chain transaction replay"
