CVE-2021-25834 Open this link in a new tabHow to fix?
Upgrade github.com/cosmos/ethermint/rpc/namespaces/eth
to version 0.4.1 or higher.
Overview
github.com/cosmos/ethermint/rpc/namespaces/eth is an a scalable, high-throughput Proof-of-Stake blockchain that is fully compatible and interoperable with Ethereum.
Affected versions of this package are vulnerable to Authentication Bypass. Signaturecheck
uses the nonce field of the transaction itself, so transactions larger than the current cached nonce can still pass it. Thus, if the victim sends a very large nonce transaction, the attacker can replay the transaction through the application.
