`RAACToken.setFeeCollector()` function doesn't allow zero address

pabloperezacc6

Summary

The RAACToken.setFeeCollector() function sets feeCollector of RAACToken and there is a check for param _feeCollector. This param should be not zero, however RAACToken allows zero address for feeCollector. Therefore, zero address can't be set as feeCollector in RAACToken.

Vulnerability Details

The check of RAACToken.setFeeCollector() function enforces the _feeCollector should not be zero.

function setFeeCollector(address _feeCollector) external onlyRole(UPDATER_ROLE) {
@> if (_feeCollector == address(0)) revert FeeCollectorCannotBeZeroAddress();
raacToken.setFeeCollector(_feeCollector);
emit ParameterUpdated("feeCollector", uint256(uint160(_feeCollector)));
}

However, feeCollector can be set to zero address to disable fee collection. As result, the feeCollector can be set zero address.

function setFeeCollector(address _feeCollector) external onlyOwner {
// Fee collector can be set to zero address to disable fee collection
if(feeCollector == address(0) && _feeCollector != address(0)){
emit FeeCollectionEnabled(_feeCollector);
}
if (_feeCollector == address(0)){
emit FeeCollectionDisabled();
}
feeCollector = _feeCollector;
emit FeeCollectorSet(_feeCollector);
}

Impact

The feeCollector in RAACToken can't be set zero.

raacToken.setFeeCollector(_feeCollector);
emit ParameterUpdated("feeCollector", uint256(uint160(_feeCollector)));
}
