Arbitrary Transfer Vulnerability in Virgo_ZodiacToken Smart Contract

CVE-2018-14089 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:P/A:N

An issue was discovered in a smart contract implementation for Virgo_ZodiacToken, an Ethereum token. In this contract, 'bool sufficientAllowance = allowance <= _value' will cause an arbitrary transfer in the function transferFrom because '<=' is used instead of '>=' (which was intended). An attacker can transfer from any address to his address, and does not need to meet the 'allowance > value' condition.
