Last modified
CVE-2018-15552 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The "PayWinner" function of a simplelottery smart contract implementation for The Ethereum Lottery, an Ethereum gambling game, generates a random value with publicly readable variable "maxTickets" (which is private, yet predictable and readable by the eth.getStorageAt function). Therefore, it allows attackers to always win and get rewards.. EPSS estimates a 1.17% chance of exploitation in the next 30 days.
