ENS Input Validation Error Vulnerability

ENS is the registrar and local resolver implementation of the Ethereum Name Service. An input validation error vulnerability exists in Ethereum Name Service version 0.0.21 and earlier, which stems from an integer overflow problem in the renew function that allows an attacker to shorten the durati...

CVE-2023-37902

Vyper is a Pythonic programming language that targets the Ethereum Virtual Machine EVM. Prior to version 0.3.10, the ecrecover precompile does not fill the output buffer if the signature does not verify. However, the ecrecover builtin will still return whatever is at memory location 0. This means...

tx.origin may be removed in future and its usage is not recommended

Lines of code Vulnerability details Impact There is a chance that tx.origin will be removed from the Ethereum protocol in the future, so code that uses tx.origin must be avoid for the authentication purpose. There is also some EIPs being proposed for change/remove of tx.origin. ethereum/EIPs637 I...

No validation check for whether the msg.value is not less than the value parameter in the execute function

Lines of code Vulnerability details Impact Users can send msg.value lesser than the supplied value parameter leading to incorrect accounting. Proof of Concept There is no check for whether msg.value = value in the execute function of the LSP0ERC725AccountCore contract. LSP0ERC725Account is in sco...

In LSP6SetDataModule.sol, Infinite loop in _verifyAllowedERC725YDataKeys()

Lines of code Vulnerability details Impact In verifyAllowedERC725YDataKeys there is a great possibility of an Infinite loop. This is because ++ii is an increment inside if condition. This can lead to excessive gas consumption, causing the Ethereum transaction to fail due to the gas limit Proof of...

Lack of Access Control in withdrawTokens Function Allows Unauthorized Token Withdrawal

Lines of code Vulnerability details Impact withdrawTokens function lacks proper access control, enabling an attacker to exploit it and withdraw tokens from the escrow to an arbitrary address, since no access control check ensures that only the DAO contract can invoke this function, and as a resul...

Setting ownership to zero account in the function _renounceOwnership()

Lines of code Vulnerability details Impact In the renounceOwnership function, the call to setOwneraddress0 sets the owner address of the contract to address0, which represents the zero address in Ethereum. This effectively removes the ownership of the contract, as the zero address is not a valid...
