CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2021-43839 – Drainage of FeeCollector's Block Transaction Fees
https://notcve.org/view.php?id=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 no tested workarounds. All validator node operators are recommended to upgrade to Cronos v0.6.5 at their earliest possible convenience. • https://github.com/crypto-org-chain/cronos/commit/150ef237b37ac28c8136e1c0f494932860b9ebe8 https://github.com/crypto-org-chain/cronos/pull/270 https://github.com/crypto-org-chain/cronos/security/advisories/GHSA-f854-hpxv-cw9r • CWE-670: Always-Incorrect Control Flow Implementation •
