Some tokens may break VotingScrow contract in transfer and transferFrom functions

Lines of code Vulnerability details Vulnerability details Some ERC20 tokens such as USDT don't return boolean values from transfer and transferFrom methods. The require checks will therefore revert causing the functions to be unusable. Impact This would prevent withdraw and createLock functions t...

User can't undelegate after he has delegated to someone who have different unlock time.

Lines of code Vulnerability details Impact User can't undelegate after he has delegated to someone who have different unlock time. It will be reverted with "Only delegate to longer lock" Proof of Concept I have created a new testcase to demonstrate this issue. I will upload it to 24 hours after...

Users can create an un-bannable contract

Lines of code Vulnerability details Impact Users can create an un-bannable contract by working from a contract's constructor and then self-destructing on each instantiation. Users can also deterministically deploy the contract to the same address every time they want to interact with fiatDAO...

CVE-2022-35961 ECDSA signature malleability in OpenZeppelin Contracts

OpenZeppelin Contracts is a library for secure smart contract development. The functions ECDSA.recover and ECDSA.tryRecover are vulnerable to a kind of signature malleability due to accepting EIP-2098 compact signatures in addition to the traditional 65 byte signature format. This is only an issu...

CVE-2022-35961

OpenZeppelin Contracts (ECDSA.recover and ECDSA.tryRecover) suffer signature malleability due to acceptance of EIP-2098 compact signatures in the single-bytes variants (not when using r, v, s or r, vs). This could allow a reused/double-submitted signature to bypass replay protection in contracts ...

User Funds are Locked in the VotingEscrow Contract When Delegated User Withdraws

Lines of code Vulnerability details Description There exists an issue when a delegated user attempts to withdraw the locked funds after a lock duration is expired, as a result the funds for the original user who triggered the delegation is lost within the contract. Impact This is an issue because...

Monero: Reentrancy attack in eth-monero atomic swap

A reentrancy vulnerability was found in the eth-xmr atomic swap smart contract, allowing an attacker to drain almost all of the ethers from the smart contract. The vulnerability was fixed in a later version of the smart contract...

Take over of AdminRole contract

Lines of code Vulnerability details Impact Any user can call the grantAdmin or revokeAdmin method and take control of the contract. Proof of Concept The grantAdmin and revokeAdmin methods are not protected by any type of authentication restriction, when they should have the onlyAdmin modifier. So...

Cronos vulnerable to DoS through unintended Contract Selfdestruct

In Cronos nodes running versions before v0.7.0, the contract selfdestruct invocation permanently removes the corresponding bytecode from the internal database storage. However, due to a bug in Ethermint, all contracts that used the identical bytecode i.e shared the same CodeHash will also stop...

The curve.finance web site was DNS hijacked on 2022-08-09 and a new smart contract that drains victims wallets if accepted is being served. Previously the DNS was registered through GoDaddy. The attack was partially mitigated through a white hat hacker that executed a SYN flooding attack against...

If a MIMOProxy owner destroys their proxy, they cannot deploy another from the same address

Lines of code Vulnerability details When deploying a new MIMOProxy, the MIMOProxyRegistry first checks whether a proxy exists with the same owner for the given address. If an existing proxy is found, the deployment reverts: MIMOProxyRegistrydeployFor function deployForaddress owner public overrid...

Overwriting storage slots in MIMOProxy

Lines of code Vulnerability details Impact The MIMOProxy allows you to delegate a call to another contract from a permission of owner. With a delegate call, the entire storage layout is kept the same as it is on MIMOProxy. It means that if the delegate call will be made for smart contract with...

Malicious manipulation of gas reserve can deny access to MIMOProxy

Lines of code Vulnerability details The MIMOProxy contract defines a minGasReserve value as a storage variable: MIMOProxy.solL18: /// @inheritdoc IMIMOProxy uint256 public override minGasReserve; The execute function uses this minGasReserve value to calculate a gas stipend to provide to the targe...

MIMOProxy: The execute function needs to verify that _initialized > 0

Lines of code Vulnerability details Impact In order to avoid changing the owner during the delegatecall, the execute function of the MIMOProxy contract will check the owner before and after the delegatecall. But if initialized is changed to 0 during the delegatecall process, the MIMOProxy contrac...

The MIMOVaultActions contract cannot withdraw assets to the user

Lines of code Vulnerability details Impact The MIMOVaultActions contract provides users with the functions of depositing, withdrawing and borrowing assets, which is called by the delegatecall of the MIMOProxy contract. But when borrowing or withdrawing assets, there is no function provided to giv...
