Vulnerability from github – Published: 2022-05-14 02:21 – Updated: 2022-05-14 02:21

Details

The doPayouts() function of the smart contract implementation for MegaCryptoPolis, an Ethereum game, has a Denial of Service vulnerability. If a smart contract that has a fallback function always causing exceptions buys a land, users cannot buy lands near that contract's land, because those purchase attempts will not be completed unless the doPayouts() function successfully sends Ether to certain neighbors.

Severity

7.5 (High)


                  
                    CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
