Descriptions

Hyperledger Iroha versions v1.0_beta and v1.0.0_beta-1 are vulnerable to transaction and block signature verification bypass in the transaction and block validator allowing a single node to sign a transaction and/or block multiple times, each with a random nonce, and have other validating nodes accept them as separate valid signatures.

Hyperledger Iroha en versiones v1.0_beta y v1.0.0_beta-1 es vulnerable a una omisión de verificación de firma de transacción y bloqueo en el validador de transacción y bloqueo. Esto permite que un único nodo firme una transacción y/o bloquee múltiples veces, cada una con un nonce aleatorio, y haga que otros nodos en validación los acepten como firmas válidas separadas.
