CVE-2018-12702

The approveAndCallcode function of a smart contract implementation for Globalvillage ecosystem GVE, an Ethereum ERC20 token, allows attackers to steal assets e.g., transfer the contract's balances into their account because the callcode i.e., spender.callextraData is not verified, aka the...

CVE-2018-12702

The CVE-2018-12702 entry concerns Globalvillage ecosystem (GVE) ERC20 contracts where approveAndCallcode allows an attacker to hijack a callback via a non-verified _spender.call(_extraData), enabling token transfers from the vulnerable contract (evilReflex). Connected sources describe the mechani...

CVE-2018-12703

The CVE-2018-12703 vulnerability affects the approveAndCallcode flow in Block 18 (18T) ERC20 contracts. The issue is that _spender.call(_extraData) is not verified, enabling an attacker to hijack the callback and trigger arbitrary contract calls from the vulnerable contract. According to the Seeb...

CVE-2018-12454

The CVE-2018-12454 entry concerns the _addguess function of the simplelottery contract in 1000 Guess. The root cause is the use of publicly readable variables (block data) combined with a private variable (readable via getStorageAt) to generate the random value. This allows an attacker to predict...

FuturXE has an unspecified vulnerability

FuturXE FXE is an ethereum-based virtual currency. A security vulnerability exists in the 'transferFrom' function of the smart contract implementation in FXE, which stems from a logic error in the program. An attacker could exploit the vulnerability to make an unauthorized transfer of digital...
