CVE-2018-12975

UnknownEPSS 1.25%

Last modified

CVE-2018-12975 is a vulnerability of currently unknown severity. The random() function of the smart contract implementation for CryptoSaga, an Ethereum game, generates a random value with publicly readable variables such as timestamp, the current block's blockhash, and a private variable (which can be read with a getStorageAt call). Therefore, attackers can precompute the random number and manipulate the game (e.g., get powerful characters or get critical damages).. EPSS estimates a 1.25% chance of exploitation in the next 30 days.
