CVE-2018-10706

An integer overflow in the transferMulti function of a smart contract implementation for Social Chain SCA, an Ethereum ERC20 token, allows attackers to accomplish an unauthorized increase of digital assets, aka the "multiOverflow" issue...

CVE-2018-10973

KoreaShow (an Ethereum ERC20 token) is affected by CVE-2018-10973 due to an integer overflow in the transferMulti function. The vulnerability arises from accumulating _value into amount with a for loop and then transferring funds, allowing a crafted _value array to overflow the total and bypass b...

CVE-2018-10705

The Owned smart contract implementation for Aurora DAO AURA, an Ethereum ERC20 token, allows attackers to acquire contract ownership because the setOwner function is declared as public. An attacker can then conduct a lockBalances denial of service attack...

CVE-2018-10705

CVE-2018-10705 affects Aurora DAO (AURA) Ethereum ERC20 token. The Owned contract’s setOwner() is public and unprotected, allowing an attacker to acquire contract ownership. Once ownership is changed, privileged functions like lockBalances() can be called, enabling a Denial-of-Service (DoS) by pr...

CVE-2018-10666

CVE-2018-10666 concerns the Owned smart contract implementation of Aurora IDEX Membership (IDXM). The vulnerability arises because setOwner is public, enabling an attacker to become contract owner. A new owner can then invoke functions protected by onlyOwner, potentially altering important variab...

Useless Ethereum Token Information Disclosure Vulnerability

Useless Ethereum Token UET is a virtual currency. A security vulnerability exists in the 'transferFrom' function implemented by smart contract in UET, which stems from the program's failure to correctly compute calculations containing the 'value' parameter. The vulnerability can be exploited by a...

CVE-2018-10468

The transferFrom function of a smart contract implementation for Useless Ethereum Token UET, an Ethereum ERC20 token, allows attackers to steal assets e.g., transfer all victims' balances into their account because certain computations involving value are incorrect, as exploited in the wild...

CVE-2018-10468

CVE-2018-10468 affects the Useless Ethereum Token (UET) ERC20 contract. The transferFrom function mishandles calculations involving _value, enabling an attacker to steal funds (e.g., drain victims’ balances). Exploitation has been observed in the wild since 2017-12. Related tokens (e.g., DimonCoi...

New proxyOverflow Bug in Multiple ERC20 Smart Contracts (CVE-2018-10376)

On 4/24/2018, 01:17:50 p.m. UTC, PeckShield again detected an unusual MESH token transaction shown in Figure 1. In this particular transaction, someone transferred a large amount of MESH token — 0x8fff,ffff,ffff,ffff,ffff,ffff,ffff,ffff,ffff,ffff,ffff,ffff,ffff,ffff,ffff,ffff 63 f’s to herself...

New batchOverflow Bug in Multiple ERC20 Smart Contracts (CVE-2018–10299)

Built on our earlier efforts in analyzing EOS tokens, we have developed an automated system to scan and analyze Ethereum-based ERC-20 token transfers. Specifically, our system will automatically send out alerts if any suspicious transactions e.g., involving unreasonably large tokens occur. In...

Beauty Ecosystem Coin smart contract integer overflow vulnerability

Beauty Ecosystem Coin BEC is a virtual currency system based on blockchain technology by the Beauty Chain Foundation. smart contract is one of the smart contracts. An integer overflow vulnerability exists in the 'batchTransfer' function of the smart contract implementation in BEC. An attacker cou...

CVE-2018-10299

An integer overflow in the batchTransfer function of a smart contract implementation for Beauty Ecosystem Coin BEC, the Ethereum ERC20 token used in the Beauty Chain economic system, allows attackers to accomplish an unauthorized increase of digital assets by providing two receivers arguments in...

CVE-2018-10299

Beauty Ecosystem Coin (BEC) smart-contract vulnerability: batchTransfer suffers an integer overflow when calculating the amount as the product of cnt and _value, enabling an attacker to inflate balances for two _receivers with a large _value. The issue is documented as batchOverflow and was obser...
