| CVE-2021-25836 | 1 Chainsafe | 1 Ethermint | 2021-02-12 | 5.0 MEDIUM | 7.5 HIGH |
| 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 memory(stateObject.code) and is further written to persistent store at the Endblock stage, which may be utilized to build honeypot contracts. | |||||
| CVE-2021-25835 | 1 Chainsafe | 1 Ethermint | 2021-02-12 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2021-25834 | 1 Chainsafe | 1 Ethermint | 2021-02-12 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2021-25837 | 1 Chainsafe | 1 Ethermint | 2021-02-12 | 5.0 MEDIUM | 7.5 HIGH |
| Cosmos Network Ethermint <= v0.4.0 is affected by cache lifecycle inconsistency in the EVM module. Due to the inconsistency between the Storage caching cycle and the Tx processing cycle, Storage changes caused by a failed transaction are improperly reserved in memory. Although the bad storage cache data will be discarded at EndBlock, it is still valid in the current block, which enables many possible attacks such as an "arbitrary mint token". | |||||
