Summary

The scoreBoard::setPrediction function contains a mathematical expression with an incorrect order of operations, leading to unintended time calculations that could affect the function's behavior.

Vulnerability Details

In the setPrediction function, there's the following time check:

However, the intended calculation should subtract 18000 before multiplying by the match number:
lets say matchnumber = 1

Impact

This vulnerability could lead to incorrect time calculations, potentially allowing predictions to be set at unintended times. Depending on the value of matchNumber, the time window for setting predictions could be significantly different from what was intended, compromising the fairness and integrity of the prediction system.

Tools Used
Manual code review

Recommendations
Add parentheses to ensure the correct order of operations:

This ensures that one interval is subtracted before multiplying by the match number.
