Use of revert Statement in requireOwner Function in Ownable Contract May Cause Unexpected Behavior

Lines of code Vulnerability details Summary: There is a potential issue with the error handling in the requireOwner function that may lead to unexpected behavior. Description: Description: The Ownable contract provides basic access control by defining an owner address that can be granted exclusiv...

createNewPosition/clonePosition/createClone are suspicious of the reorg attack

Lines of code Vulnerability details Description The createNewPosition function creates a new position smart contract and returns its address. The address is determined by create address derivation, that depends on the contract nonce. Later user could use interact with newly created contract. At t...

Signature malleability for S

Lines of code Vulnerability details Impact Ethereum contracts often assumes that the signature is unique, but signatures can be altered without the possession of the private key and still be valid. The EVM specification defines several so-called ‘precompiled’ contracts one of them being ecrecover...

Design/Logic Flaw

@web3-react is a framework for building Ethereum Apps . In affected versions the chainId may be outdated if the user changes chains as part of the connection flow. This means that the value of chainId returned by useWeb3React may be incorrect. In an application, this means that any data derived...

CVE-2023-30543 `chainId` may be outdated if user changes chains as part of connection in @web3-react

@web3-react is a framework for building Ethereum Apps . In affected versions the chainId may be outdated if the user changes chains as part of the connection flow. This means that the value of chainId returned by useWeb3React may be incorrect. In an application, this means that any data derived...

CVE-2023-30543

Con concrete details: The CVE-2023-30543 entry concerns @web3-react, where chainId can become outdated during a user’s chain-switch in the connection flow. The root cause is that useWeb3React() may return an incorrect chainId, causing dependent data (e.g., wrapped token addresses) to be computed ...

if revertOnFailure is set to false, batchContributeFor doesn't refund properly

Lines of code Vulnerability details Proof of Concept Consider the code for batchContributeFor: function batchContributeFor BatchContributeForArgs calldata args external payable onlyDelegateCall returns uint96 memory votingPowers uint256 numContributions = args.recipients.length; votingPowers = ne...

It's not always possible for a user to claim their voting power in ReraiseETHCrowdfund

Lines of code Vulnerability details Proof of Concept When a ReraiseETHCrowdfund has finalized, a user has 2 ways to claim their voting power - claim or claimMultiple. The condition in claim is that user's total contribution is no greater than the maxContribution. uint96 contribution = votingPower...

ETHCrowdfundBase.sol: totalVotingPower is increased too much in the _finalize function

Lines of code Vulnerability details Impact This issue is about how the ETHCrowdfundBase.finalize functions calls PartyGovernanceNFT.increaseTotalVotingPower with an amount that does not reflect the sum of the individual users' voting power. Thereby it will become impossible to reach unanimous...

ETHCrowdfundBase.sol: all funds are lost when fee recipient cannot receive ETH

Lines of code Vulnerability details Impact In the ETHCrowdfundBase contract a fundingSplitRecipient address is configured which receives a percentage of the funds in case the crowdfund is won. Neither the fundingSplitRecipient address nor the fundingSplitBps percentage can be changed. The issue i...

MuteAmplifier.rescueTokens() should check conditions for fee tokens(token0/token1) as well

Lines of code Vulnerability details Impact rescueTokens can be used to withdraw fee tokens without any validations. As a result, the reward logic would be broken due to the lack of fee tokens. Proof of Concept rescueTokens doesn't validate anything for the fee tokens. So if some fee tokens were...

MuteBond.sol: deposit function reverts if remaining payout is very small due to >0 check in dMute.LockTo function

Lines of code Vulnerability details Impact I will show in this report how the MuteBond.deposit function can experience a temporary DOS. The attacker or just any other user by mistake or by not knowing about it can receive a payout from the deposit function that puts the payoutTotal of the current...

Reth flashloan attack

Lines of code Vulnerability details Impact Using a flashloan to manipulate rETH/ETH price a hacker can receive more SafEth shares for the same amount of ether, thus draining all three derivative contracts rETH, SfrxEth and WstEth. Proof of Concept Reth.poolPrice depends on UniswapV3 pool.slot0...

In stake() function shares increase exponentially for the same amount of deposit as the totalSupply() increases, causing the loss for the initial stakers relative to later ones.

Lines of code Vulnerability details Impact Stake function don not allocate the safEth according to the totalShares, instead as more user deposit, later depositers get higher share of the value as compared to ealy depositers. Proof of Concept Consider Alice, Bob and Jenny want to stake their eth...

CVE-2023-28431

Frontier is an Ethereum compatibility layer for Substrate. Frontier's modexp precompile uses num-bigint crate under the hood. In the implementation prior to pull request 1017, the cases for modulus being even and modulus being odd are treated separately. Odd modulus uses the fast Montgomery...

CVE-2023-28431

CVE-2023-28431 describes a vulnerability in Frontier’s modexp precompile used by Substrate. The implementation treats even and odd moduli differently: odd moduli use Montgomery multiplication, while even moduli fall back to a slower plain power algorithm. This mismatch caused a gas-cost discrepan...
