CVE-2021-43839

Cronos is a commercial implementation of a blockchain. In Cronos nodes running versions before v0.6.5, it is possible to take transaction fees from Cosmos SDK's FeeCollector for the current block by sending a custom crafted MsgEthereumTx. This problem has been patched in Cronos v0.6.5. There are ...

CVE-2021-25836

Cosmos Network Ethermint = v0.4.0 is affected by cache lifecycle inconsistency in the EVM module. The bytecode set in a FAILED transaction wrongfully remains in memorystateObject.code and is further written to persistent store at the Endblock stage, which may be utilized to build honeypot contrac...

CVE-2021-25835

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 conte...

CVE-2021-25834

Cosmos Network Ethermint = v0.4.0 is affected by a transaction replay vulnerability in the EVM module. If the victim sends a very large nonce transaction, the attacker can replay the transaction through the application...
