Technical ContextAI · show details

This vulnerability is classified as Exposure of Resource to Wrong Sphere (CWE-668), which allows attackers to access resources from an unintended security context. Ethermint is an Ethereum library. In Ethermint running versions before v0.17.2, the contract selfdestruct invocation permanently removes the corresponding bytecode from the internal database storage. However, due to a bug in the DeleteAccountfunction, all contracts that used the identical bytecode (i.e shared the same CodeHash) will also stop working once one contract invokes selfdestruct, even though the other contracts did not invoke the selfdestruct OPCODE. This vulnerability has been patched in Ethermint version v0.18.0. The patch has state machine-breaking changes for applications using Ethermint, so a coordinated upgrade procedure is required. A workaround is available. If a contract is subject to DoS due to this issue, the user can redeploy the same contract, i.e. with identical bytecode, so that the original contract's code is recovered. The new contract deployment restores the bytecode hash -> bytecode entry in the internal state. Affected products include: Evmos Ethermint, Kava, Crypto Cronos, Evmos.
