Lines of code Vulnerability details Mitigation of M-02: Issue partially mitigated, see comments Link to Issue: code-423n4/2023-05-ambire-findings18 Comments While the issue mentioned in M-02 has been technically mitigated, the same attack can be performed in another function present in the wallet...

Front-running of the relayers transaction

Lines of code Vulnerability details Description While the relayer has a positive outcome from the execution of some of the user operations through gas refund it is profitable for the attacker to front-run such transactions with a full copy of those. In such a case attacker receives a positive...

Unsigned tokenGasPriceFactor parameter

Lines of code Vulnerability details Description For the calculation of the amount of the token to be paid to the relayer tokenGasPriceFactor value is used. The corresponding logic is the following: payment = gasUsed + baseGas gasPrice / tokenGasPriceFactor; requiretransferTokengasToken, receiver,...

Incorrect management of requested gas amount in EIP-4337 logic

Lines of code Vulnerability details Description According to the EIP-150 call can consume as most 63/64 of parent calls' gas. That means that it is possible to manipulate the gas amount to be passed into calls mentioned in the "Links to affected code" section. Specifically, if the amount of gas...

Griefing attacks on handleOps and multiSend logic

Lines of code Vulnerability details Description The handleOps function executes an array of UserOperation. If at least one user operation fails the whole transaction will revert. That means the error on one user ops will fully reverts the other executed ops. The multiSend function reverts if at...

Potential security issues in CrossChainExecutorOptimism contract

Lines of code Vulnerability details Title: Potential security issues in CrossChainExecutorOptimism contract Product: CrossChainExecutorOptimism contract Version: 0.8.16 Summary: The CrossChainExecutorOptimism contract contains several potential security issues that could allow unauthorized or...

the executor can execute fake cross-chain function call

Lines of code Vulnerability details Impact The caller on relayer side can be rugged if the executor call the executeCall on execution side directly to use consume the nonce and fake cross-chain function call. Proof of Concept The expected behavior is that: the relayer relays a cross-chain request...

Relayer/executor-already-set Error in CrossChainRelayerArbitrum Contract

Lines of code Vulnerability details Summary The setExecutor function in the CrossChainRelayerArbitrum contract improperly reverts when the executor variable has already been set. Impact This bug could prevent the CrossChainRelayerArbitrum contract from properly setting the executor variable,...

Potential reentrancy attack

Lines of code Vulnerability details Impact There is a potential of reentrancy attack in executeCalls in EthereumToArbitrumExecutor.sol since CallLib is making an external call with its executeCalls and we do not know the implementation of the contract that will be called eventually. The same issu...

Malicious relayer can execute stale transactions by spoofing validator weights/threshold in proof

Lines of code Vulnerability details Impact Transaction is submit with wrong validator information, allowing stale commands to be executed Proof of Concept This vulnerability is a result of allowing msg.sender to provide key information identifying operators. First we need to understand how the...

Malicious relayer could exploit sponsor vaults

Lines of code Vulnerability details Impact Sponsor vaults drained Proof of Concept reimburseRelayerFees uses SponsorVault funds to repay users the fees they pay to relayers. A malicious relayer could create a large number of transactions with the max reimbursed relay fee specified in SponsorVault...

Relayer Will Not Receive Any Fee If execute Reverts

Lines of code Vulnerability details Proof-of-Concept Connext relies on the relayer to trigger the BridgeFacet.execute function on the destination domain to initiate the token transfer and calldata execution processes. Relayers pay for the gas cost to trigger the execute function, and in return fo...

Malicious Relayer Could Cause A Router To Provide More Liquidity Than It Should

Lines of code Vulnerability details Proof-of-Concept Assume this is a fast-transfer path and the sequencer has a good reason e.g. some sophisticated liquidity load balancing algorithm to assign 3 routers to provide liquidity for a transfer of 90 DAI Therefore, each of them will provide 30 DAI...
