StabilizerNode.stabilize() should update lastTracking as well to avoid an unnecessary incentive.

Lines of code Vulnerability details Impact StabilizerNode.stabilize should update lastTracking as well to avoid an unnecessary incentive. Current logic pays unnecessary incentives to track the pool. Proof of Concept trackPool pays an incentive per trackingBackoff in order to ensure pool...

Function stabilize() might always revert because of overflow since Malt contract use solidity 0.8

Lines of code Vulnerability details Impact MaltDataLab fetched priceCumulative directly from Uniswap V2 pool to calculate price of Malt token. However, it is noticed that Uniswap V2 pool use Solidity 0.5.16, which does not revert when overflow happen. In addition, it is actually commented in...

Average APRs might be calculated wrongly after calling populateFromPreviousThrottle().

Lines of code Vulnerability details Impact Average APRs might be calculated wrongly after calling populateFromPreviousThrottle and targetAPR might be changed unexpectedly. Proof of Concept The epoch state struct contains cumulativeCashflowApr element and cashflowAverageApr is used to adjust...

LinearDistributor.declareReward can revert due to dependency of balance

Lines of code Vulnerability details Impact LinearDistributor.declareReward will revert and it can cause permanent DOS. Proof of Concept In LinearDistributor.declareReward, if the balance is greater than the bufferRequirement, the rest will be forfeited. if balance bufferRequirement // We have mor...

RewardThrottle.setTimekeeper: If changing the timekeeper causes the epoch to change, it will mess up the system

Lines of code Vulnerability details Impact RewardThrottle.setTimekeeper allows POOLUPDATERROLE to update the timekeeper when RewardThrottle is active, function setTimekeeperaddress timekeeper external onlyRoleMaltPOOLUPDATERROLE, "Must have pool updater privs" requiretimekeeper != address0, "Not...

latestSample can be manipulation to make stabilize() calls always fail

Lines of code Vulnerability details Impact In function stabilize, in case exchangeRate priceTarget, which means price of Malt is larger than $1 so it has to sell Malt to return to $1. However, team don't want to sell Malt when the market is too volatile price changing too fast, so they added some...

SwingTraderManager.swingTraders() shoudn't contain duplicate traderContracts.

Lines of code Vulnerability details Impact If SwingTraderManager.swingTraders contains duplicate traderContracts, several functions like buyMalt and sellMalt wouldn't work as expected as they work according to traders' balances. Proof of Concept During the swing trader addition, there is no...

The latest malt price can be less than the actual price target and StabilizerNode.stabilize will revert

Lines of code Vulnerability details Impact StabilizerNode.stabilize will revert when latestSample priceTarget and msgSender is not an admin and not whitelisted, it asserts livePrice minThreshold. And minThreshold is calculated as follows: uint256 priceTarget = maltDataLab.getActualPriceTarget;...

An early check logic in StabilizerNode.stabilize prevents possible stabilization.

Lines of code Vulnerability details Impact An early check logic in StabilizerNode.stabilize prevents possible stabilization. Proof of Concept In StabilizerNode.stabilize, there is an early check logic for exchangeRate and auction state. If shouldAdjustSupply returns false, stabilize will end...

RewardThrottle.checkRewardUnderflow() might track the cumulative APRs wrongly.

Lines of code Vulnerability details Impact RewardThrottle.checkRewardUnderflow might calculate the cumulative APRs for epochs wrongly. As a result, cashflowAverageApr will be calculated incorrectly in updateDesiredAPR, and targetAPR would be changed unexpectedly. Proof of Concept In...

SwingTraderManager.sellMalt() doesn't update totalProfit for some cases.

Lines of code Vulnerability details Impact SwingTraderManager.totalProfit would be less than the real amount and the impact might be low as this amount isn't used elsewhere. After the second look, I think the SwingTraderManager itself might be used as a swing trader againI am not sure the protoco...

RewardThrottle.checkRewardUnderflow can't distribute rewards because fillInEpochGaps updates activeEpoch when RewardThrottle is inactive

Lines of code Vulnerability details Impact RewardThrottle.checkRewardUnderflow can't distribute rewards because activeEpoch can be updated to a new one. Proof of Concept RewardThrottle.checkRewardUnderflow distributes rewards only when RewardThrottle is active. function checkRewardUnderflow publi...

Repository._removeContract() removes the contract wrongly.

Lines of code Vulnerability details Impact After removing the contract, the contracts array would contain the wrong contract names. Proof of Concept Repository.removeContract removes the contract name from contracts array. File: 2023-02-malt\contracts\Repository.sol 223: function...

LinearDistributor.declareReward() might revert after changing vestingDistributor.

Lines of code Vulnerability details Impact LinearDistributor.declareReward might revert after changing vestingDistributor due to uint underflow. Proof of Concept In LinearDistributor.sol, there is a setVestingDistributor function to update vestingDistributor. And in declareReward, it calculates t...
