Arbitrary contract call allows attacker to steal from user's wallet

Lines of code Vulnerability details Impact In function prepareGate , in the following line : bool s, bytes memory r = addressgateKeeper.callcreateGateCallData; A call to an arbitrary contractgateKeeper with custom calldata createGateCallData is made in prepareGate, which means the contract...

Cross-chain smart contract calls can revert but source chain tokens remain burnt and are not refunded

Lines of code Vulnerability details Impact Smart contract calls often revert. In such cases any ether sent along with the transaction is returned and sometimes the remaining gas depending on whether an assert caused the reversion or not. For contracts involving ERC20 tokens it is also expected...

Arbitrary contract call within UniV3LpVault._swap with controllable swapPath

Lines of code Vulnerability details Impact UniV3LpVault.swap utilizes swapRouter.exactInput to perform swaps between two tokens. During swaps, transfer function of each token along the path will be called to propagate the assets. Since anyone can create a uniswap pair of arbitrary assets, it is...

CVE-2018-17877

A lottery smart contract implementation for Greedy 599, an Ethereum gambling game, generates a random value that is predictable via an external contract call. The developer used the extcodesize function to prevent a malicious contract from being called, but the attacker can bypass it by writing t...
