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...

Code injection

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...

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-2018-10666

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...

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...

Integer overflow

An integer overflow in the transferProxy function of a smart contract implementation for SmartMesh aka SMT, an Ethereum ERC20 token, allows attackers to accomplish an unauthorized increase of digital assets via crafted fee and value parameters, as exploited in the wild in April 2018, aka the...

CVE-2018-10376

CVE-2018-10376 concerns an integer overflow in the transferProxy function of the SmartMesh (SMT) ERC20 smart contract. The root cause is an overflow when values are computed with the input parameters _fee and _value, enabling an attacker to increase token balances beyond legitimate amounts. The v...

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...
