CVE-2018-15552

The "PayWinner" function of a simplelottery smart contract implementation for The Ethereum Lottery, an Ethereum gambling game, generates a random value with publicly readable variable "maxTickets" which is private, yet predictable and readable by the eth.getStorageAt function. Therefore, it allow...

CVE-2018-15552

The CVE describes a vulnerability in the PayWinner function of a simplelottery smart contract used by The Ethereum Lottery. The root cause is that the function uses the publicly readable storage variable maxTickets (private in code) to generate a random value, which is readable via eth.getStorage...

Bitcoin Red Integer Overflow Vulnerability

Bitcoin Red BTCR is an Ether-based digital currency. An integer overflow vulnerability exists in the 'distributeBTR' function in BTCR's smart contract implementation. An attacker can exploit the vulnerability to increase the balance of their own account...

All For One Information Disclosure Vulnerability

All For One is an Ether-based gambling game. An information disclosure vulnerability exists in the 'maxRandom' function in All For One's smart contract implementation, which stems from the program's use of publicly readable variables to generate arbitrary values. An attacker could use the...

Design/Logic Flaw

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...

Integer overflow

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-2018-11687

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 ...

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...

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...

CVE-2018-11561

An integer overflow in the unprotected distributeToken function of a smart contract implementation for EETHER EETHER, an Ethereum ERC20 token, will lead to an unauthorized increase of an attacker's digital assets...

CVE-2018-11561

An integer overflow in the unprotected distributeToken function of a smart contract implementation for EETHER EETHER, an Ethereum ERC20 token, will lead to an unauthorized increase of an attacker's digital assets...

CVE-2018-11561

CVE-2018-11561 affects the EETHER ERC20 smart contract; an integer overflow in the unprotected distributeToken function enables an attacker to illegitimately increase their digital assets. The vulnerability is described in multiple sources (NVD/CNVD) as a token-amount overflow in the distributeTo...

Design/Logic Flaw

The randMod function of the smart contract implementation for MyCryptoChamp, an Ethereum 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, attackers can get powerful...
