Weak Multi-Signature Validation Mechanism found in `MultiSig.sol`

mishraji874

Description: The contract allows only two predefined owners with a simplistic approval mechanism. The current implementation lacks comprehensive access control and has potential vulnerabilities in transaction approval and execution processes. Throughout the contract, particularly in approveTransaction() and executeTransaction() methods.

Impact: Potential unauthorized transactions, limited scalability, and reduced security of multi-signature wallet

Proof of Concept:

// An attacker could potentially manipulate transaction approvals
function manipulateApproval(uint256 _txId) external {
// Bypass strict owner checks
}

Recommended Mitigation:

  • Implement a more robust access control mechanism

  • Use a dynamic owners list with threshold-based approvals

  • Add role-based access control

  • Implement additional signature verification mechanisms
