Last modified

CVE-2018-13877 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.05% chance of exploitation in the next 30 days.
