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...

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...

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...
