CVE-2023-36980Network attack vector

Permanent fund loss via unchecked bet parameters

Published Sep 11, 2023 · Updated Sep 26, 2024

Incorrect calculation in an Ethereum casino smart contract allows remote attackers to cause permanent participant fund loss. The public betOnNumber function derives betSize from msg.value, insufficiently validates monetary parameters, and updates casino.balance without checking whether send() succeeded. Any blockchain participant can call the function, but the published record identifies neither the deployed contract address nor a canonical product.
