{"id":"CVE-2024-32644","state":"PUBLISHED","title":"Evmos' transaction execution not accounting for all state transition after interaction with precompiles","description":"Evmos is a scalable, high-throughput Proof-of-Stake EVM blockchain that is fully compatible and interoperable with Ethereum. Prior to 17.0.0, there is a way to mint arbitrary tokens due to the possibility to have two different states not in sync during the execution of a transaction. The exploit is based on the fact that to sync the Cosmos SDK state and the EVM one, we rely on the `stateDB.Commit()` method. When we call this method, we iterate though all the `dirtyStorage` and, **if and only if** it is different than the `originStorage`, we set the new state. Setting the new state means we update the Cosmos SDK KVStore.  If a contract storage state that is the same before and after a transaction, but is changed during the transaction and can call an external contract after the change, it can be exploited to make the transaction similar to non-atomic. The vulnerability is **critical** since this could lead to drain of funds through creative SC interactions.
