Vulnerability details

Impact

Without proper input validation, it is possible for attackers to pass malicious input to the contract, potentially causing unintended behavior or even allowing the attacker to exploit the contract.

Proof of Concept

an attacker could pass a negative value as the ‘amount’ parameter to the ‘burnFrom’ function, which could allow them to destroy more tokens than they are supposed to be able to. Similarly, an attacker could pass an invalid address as the ‘account’ parameter, which could cause the function to behave unexpectedly.

Tools Used

Myrthil

Recommended Mitigation Steps

add input validation to the contract to ensure that the inputs are within the expected range and conform to the required format. For example, you could add a check to ensure that the ‘amount’ parameter is greater than zero and that the ‘account’ parameter is a valid address.
