Attack on Pseudo-random number generator (PRNG) used in 1000 Guess, an Ethereum lottery game. (CVE-2018–12454)

Abstract An Ethereum lottery game, 1000 Guess, has a vulnerability that it generates random numbers predictable by anyone. This game decides a winner by a random number when the number of players who bet on the contract reaches to the predetermined number. The contract generates the random number...

CVE-2018-12520

An issue was discovered in ntopng 3.4 before 3.4.180617. The PRNG involved in the generation of session IDs is not seeded at program startup. This results in deterministic session IDs being allocated for active user sessions. An attacker with foreknowledge of the operating system and standard...

1000 Guess has an unspecified vulnerability

1000 Guess is an ethereum-based random number guessing game. A security vulnerability in the 'addguess' function of the implementation of the simplelottery smart contract in 1000 Guess stems from the program's use of publicly readable variables to generate random values. An attacker could exploit...
