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.

Weakness

The product does not verify, or incorrectly verifies, the cryptographic signature for data.
