CVE-2018-17968

CVE-2018-17968 concerns a gambling smart contract for RuletkaIo on Ethereum. The vulnerability arises from a flawed random() function that relies on block timestamp and block hash, enabling an external contract to predict the generated random value. The description notes that an attacker could re...

CVE-2018-17877

CVE-2018-17877 concerns a lottery Smart Contract for Greedy 599 (Ethereum). The vulnerability: the contract generates a random value that is predictable through an external contract call. The developer attempted to prevent malicious contracts with extcodesize(), but an attacker can bypass this by...

Design/Logic Flaw

The fallback function of a simple lottery smart contract implementation for Lucky9io, an Ethereum gambling game, generates a random value with the publicly readable variable entrynumber. This variable is private, yet it is readable by eth.getStorageAt function. Also, attackers can purchase a tick...

CVE-2018-17071

The CVE (CVE-2018-17071) concerns the fallback function of a simple lottery smart contract used in Lucky9io, an Ethereum gambling game.
