Hawk High

Summary

Teachers receive 40% of the school fee pot instead of 35%.

Vulnerability Details

The invariant says:

Payment structure is as follows:

• principal gets 5% of bursary

• teachers share of 35% of bursary

• remaining 60% should reflect in the bursary after upgrade

However, as we can see in LevelTwo.sol:

uint256 public constant TEACHER_WAGE_L2 = 40;

That means that teachers get more funds than intended.

Impact

Teachers are overpaid, and the school receives a smaller share.
