First Flight #3: Thunder Loan

Summary

Contract has uninitialized state variables, specifically s_feePrecision and s_flashLoanFee. Failing to initialize these variables during deployment can lead to unexpected behavior in the contract.

Vulnerability Details

In contract, the s_feePrecision and s_flashLoanFee state variables are declared but not initialized during contract deployment. The lack of proper initialization means that these variables will have a default value of 0, which can lead to incorrect fee calculations and unexpected behavior in the contract.

Impact

The impact of uninitialized state variables can vary depending on how these variables are used within the contract. In this case, the impact can be significant:

• Incorrect Fee Calculations: The s_feePrecision and s_flashLoanFee variables are used in fee calculations in the contract. Failing to initialize them can lead to incorrect fee calculations, potentially resulting in users being charged incorrect fees during flash loans.

• Unexpected Behavior: Uninitialized state variables can result in unexpected behavior, including division by zero errors or other unintended consequences that may compromise the contract's functionality and security.

Tools Used

No specific tools were used for this analysis. The vulnerability was identified through manual code review.

Recommendations

1. Initialize State Variables: Ensure that state variables s_feePrecision and s_flashLoanFee are correctly initialized during contract deployment with appropriate values.
   By initializing these variables, you prevent unexpected behavior and ensure the correct operation of the contract, especially in fee calculations.
