New ownerAnyone Bug Allows For Anyone to ''Own'' Certain ERC20-Based Smart Contracts (CVE-2018-10705)

This morning, our vulnerability-scanning system at PeckShield identified a new vulnerability named ownerAnyone in certain ERC20-based smart contracts such as AURA, which is deployed by a decentralized banking and finance platform – AURORA. This bug, if successfully exploited, might introduce the...

New allowAnyone Bug Identified in Multiple ERC20 Smart Contracts (CVE-2018-11397, CVE-2018-11398)

Our vulnerability-scanning system at PeckShield has so far discovered several dangerous smart contract vulnerabilities batchOverflow1, proxyOverflow2, transferFlaw3, ownerAnyone4, multiOverflow5, burnOverflow6, ceoAnyone7. Some of them could be used by attackers to generate tokens out of nowhere ...

CVE-2018-11239

CVE-2018-11239 affects Hexagon (HXG), an Ethereum ERC20 token. The vulnerability is an integer overflow in the _transfer function, where _value + burnPerTransaction can overflow, bypassing balance checks and enabling an attacker to inflate the recipient’s balance. PeckShield reports a real-world ...

CVE-2018-10944

CVE-2018-10944 concerns ROC (Rasputin Online Coin), an Ethereum ERC20 token. The smart contract’s request_dividend() function is vulnerable: it computes holder_token_balance and holder_profit and then sends Ether to the address without updating the sender’s balance, and it is declared public with...
