CVE-2018-12454 (GCVE-0-2018-12454)

Vulnerability from cvelistv5 – Published: 2018-06-17 12:00 – Updated: 2024-08-05 08:38

Summary

The _addguess function of a simplelottery smart contract implementation for 1000 Guess, an Ethereum gambling game, generates a random value with publicly readable variables such as the current block information and a private variable (which can be read with a getStorageAt call). Therefore, it allows attackers to always win and get rewards.

Severity

No CVSS data available.
