CVE-2018-12511: Integer Overflow or Wraparound

In the mintToken function of a smart contract implementation for Substratum SUB, an Ethereum ERC20 token, the administrator can control mintedAmount, leverage an integer overflow, and modify a user account's balance arbitrarily...

CVE-2018-17071

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. The vulnerability arises because the contract generates a random value using the publicly readable storage variable entry_number, which is privately defined but ...

CVE-2018-17111

The onlyOwner modifier of a smart contract implementation for Coinlancer CL, an Ethereum ERC20 token, has a potential access control vulnerability. All contract users can access functions that use this onlyOwner modifier, because the comparison between msg.sender and owner is incorrect...

PT-2018-13903

Name of the Vulnerable Software and Affected Versions Coinlancer CL affected versions not specified Description The issue concerns a smart contract implementation for an Ethereum ERC20 token. It involves an access control problem with the onlyOwner modifier. Due to an incorrect comparison between...

PT-2018-13876

Name of the Vulnerable Software and Affected Versions Lucky9io affected versions not specified Description The issue concerns a simple lottery smart contract implementation for Lucky9io, an Ethereum gambling game. It allows attackers to always win and get rewards due to a couple of flaws. Firstly...

CVE-2018-17071: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

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-2018-17111: Undefined Security Weakness

The onlyOwner modifier of a smart contract implementation for Coinlancer CL, an Ethereum ERC20 token, has a potential access control vulnerability. All contract users can access functions that use this onlyOwner modifier, because the comparison between msg.sender and owner is incorrect...

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...

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...

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...

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...

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...
