Submission Details
Severity:
Missing zero address check in YieldFacet
Vulnerability Details
Identifier: M-08
Description: No checks for
_dittonot being the zero address.
Code Snippet:
In YieldFacet.sol:31,
IAsset private immutable DITTO;
constructor(address _ditto) {
DITTO = IAsset(_ditto);
}
Impact
If the _ditto address provided to the constructor is the zero address, the smart contract would set its DITTO state variable to this invalid address. Any interactions or operations using this address can lead to unexpected behavior.
Tools Used
Manual Review
Recommendations
Add a validation check in the constructor to ensure that the _ditto address is not the zero address.
