CVE-2018-12056

Affected software: All For One’s Ethereum-based gambling contract. Vulnerability: The maxRandom function generates a random value using publicly readable variables because the _seed can be retrieved with getStorageAt, enabling attackers to predict the outcome. Impact: Attackers could always win a...

CVE-2018-11687

An integer overflow in the distributeBTR function of a smart contract implementation for Bitcoin Red BTCR, an Ethereum ERC20 token, allows the owner to accomplish an unauthorized increase of digital assets by providing a large address array, as exploited in the wild in May 2018, aka the...

CVE-2018-12056

The maxRandom function of a smart contract implementation for All For One, an Ethereum gambling game, generates a random value with publicly readable variables because the seed value can be retrieved with a getStorageAt call. Therefore, it allows attackers to always win and get rewards...

CVE-2018-11687

The Bitcoin Red (BTCR) smart contract, an Ethereum ERC20 token, contains an integer overflow vulnerability in its distributeBTR function. By providing a large address[] array, an owner can trigger this overflow to perform an unauthorized increase of digital assets . This issue, known as the "owne...

CVE-2018-12056: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

The maxRandom function of a smart contract implementation for All For One, an Ethereum gambling game, generates a random value with publicly readable variables because the seed value can be retrieved with a getStorageAt call. Therefore, it allows attackers to always win and get rewards...

SmartMesh Replay Attack Vulnerability

SmartMesh SMT is a blockchain-based underlying protocol for the Internet of Things IoT, positioned in the areas of meshless communication, meshless payment, and more. The 'transferProxy' and 'approveProxy' functions in SMT's smart contract are vulnerable to replay attacks, which can be exploited ...

MyCryptoChamp Information Disclosure Vulnerability

MyCryptoChamp is an ethereum-based blockchain game. An information disclosure vulnerability exists in the 'randMod' function in MyCryptoChamp's smart contract implementation, which stems from the fact that the 'randMod' function generates a publicly readable variable containing a public readable...

EETHER integer overflow vulnerability

EETHER is an Ether-based digital currency. An integer overflow vulnerability exists in the unprotected 'distributeToken' function in EETHER's smart contract implementation. An attacker could exploit the vulnerability to increase their digital assets...

CVE-2018-11561
