Migration's withdrawContribution ignores the exchange between fractional tokens and ETH happened during Buyout attempt

Lines of code Vulnerability details withdrawContribution aims to return the funds to Migration participants. However, it uses initial userProposalFractionsproposalIdmsg.sender and userProposalEthproposalIdmsg.sender records for withdrawal accounting. Real funds structure is different after Buyout...

Loss of funds in an underlying protocol would cause catostrophic loss of funds for swivel

Lines of code Vulnerability details Impact Loss of all user funds Proof of Concept This exploit stems from a quirk in the way that exchange rate is tracked for matured positions. We first need to breakdown how interest is calculate for a matured position. In L124 the yield for a matured position ...

function mint() in FERC1155 don't follow check-effect-interact pattern, it's possible to call protocol contracts after tokens minted and before totalSupply updated

Lines of code Vulnerability details Impact Function mint mints new fractions for an ID and is only callable by VaultRegistry. code mints tokens then updates totalSupply value. when minting contract may make external call to target address, in that external call contract state is wrong, tokens are...

The vulnerability of Schneider Electric CanBrass software for designing and calculating the cost of hose pipelines lies in the fact that operations can be executed outside the buffer in memory, allowing an attacker to execute arbitrary code.

The vulnerability of Schneider Electric CanBrass’s software for designing and calculating hose pipe costs is related to the execution of operations beyond the buffer boundaries in memory. Exploiting this vulnerability could allow an attacker to execute arbitrary code...

No check for stale chainlink oracle data in currentPrice function

Lines of code Vulnerability details Impact There is no check if the value of price returned by chainlink latestRoundData is latest or stale. If stale price is returned, it may result in wrong calculation used further, and in JBPrices.sol Proof of Concept Contract : JBChainlinkV3PriceFeed.sol Line...

Inaccurate fee calculation

Lines of code Vulnerability details Impact The equation in the calculateFee function has a high degree of inaccuracy Solidity use integers, when divide an uint256 for other uint256 the divition take the floor number and ignore the decimal part In example: a = 1999 ETH feenominator = 1000 the retu...

Avoid using address(this).balance for internal accounting

Lines of code Vulnerability details Impact This could reduce or increase the amount of ETH that token-holders are able to redeem for a reserve token in the case of a buyout success. Proof of Concept Using addressthis.balance for any internal accounting for smart contract poses risks. Using...

Issue with TWAV calculation.

Lines of code Vulnerability details Impact To calculate time weighted average value, current valuation is used. This is not appropriate way to decide the TWAV while other locations considers only time. This might not be the stable one. Proof of Concept uint256 currentValuation =...

_getTwav is not correct. It is not considering all last 4 blocks.

Lines of code Vulnerability details Impact This will result in invalid deadline to decide the buyout end. Proof of Concept /// @notice returns the TWAV of the last 4 blocks /// @return twav TWAV of the last 4 blocks function getTwav internal view returnsuint256 twav if...

[PNM-004] Calculation of _secondaryReserveRatio can be overflowed

Lines of code Vulnerability details Description uint32 secondaryReserveRatio = uint32msg.value SCALE 1e18 / initialTokenSupply initialTokenPrice; secondaryReserveRatio can be overflowed by setting a relatively small initialTokenSupply and initialTokenPrice. The result will be truncated by uint32,...

[PNM-005] Reentrancy of function sell

Lines of code Vulnerability details Description In function chargeFee, a potential reetrancy can be triggered by the factory. Since function sell invokes chargeFee in the middle of its function body, it potentially impacts the calculation, e.g., the totalSupply would be incorrect since the tokens...

The amount of gas calculation for refunding is incorrect

Lines of code Vulnerability details Impact While matching the orders the gas cost is calculated so that it can be refunded back to the contract. The calculation for this gas is incorrect. The function keeps track of the gasleft at the beginning of the loop and adds additional amount of gas for pr...
