Virgin stake can claim all drops

Lines of code Vulnerability details Impact If wxETH drips when nothing is staked, then the first staker can claim every drop. Proof of Concept Suppose drip is enabled when totalSupply == 0. At least one block passes and the first staker stakes, just 1 xETH is enough. This mints her 1 wxETH. This...

[H1] Incorrect constant set at WhitePaperInterestRateModel

Lines of code Vulnerability details Impact Incorrect calculation of critical parameters like baseRatePerBlock. Proof of Concept The constant blocksPerYear is incorrectly set uint256 public constant blocksPerYear = 2102400; // @audit 15 seconds per block However, for Binance Smart Chain the blocks...

Wrong WhitePaperInterestRateModel block per year calculations incur losses for users and the protocol

Lines of code Vulnerability details Vulnerability Details Blocks per year calculations in WhitePaperInterestRateModel improperly assume 15 seconds block time, while on Binance Smart Chain it’s 3 seconds. This has grave consequences, because it is used in calculating borrower’s interest rate and...

Shortfall.sol#initialize's waitForFirstBidder and nextBidderBlockLimit too short

Lines of code Vulnerability details Impact File: Shortfall.sol 147 waitForFirstBidder = 100; 148 nextBidderBlockLimit = 10; Binance Smart Chain has a block time of around 3 seconds. This could lead to an attacker blocking other bids to bid for the token at a low price. Proof of Concept Tools Used...

CVE-2023-32059

Vyper is a Pythonic smart contract language for the Ethereum virtual machine. Prior to version 0.3.8, internal calls with default arguments are compiled incorrectly. Depending on the number of arguments provided in the call, the defaults are added not right-to-left, but left-to-right. If the type...

CVE-2023-32058

Vyper is a Pythonic smart contract language for the Ethereum virtual machine. Prior to version 0.3.8, due to missing overflow check for loop variables, by assigning the iterator of a loop to a variable, it is possible to overflow the type of the latter. The issue seems to happen only in loops of...

CVE-2023-31146

Vyper is a Pythonic smart contract language for the Ethereum virtual machine. Prior to version 0.3.8, during codegen, the length word of a dynarray is written before the data, which can result in out-of-bounds array access in the case where the dynarray is on both the lhs and rhs of an assignment...

CVE-2023-32059 Vyper vulnerable to incorrect ordering of arguments for kwargs passed to internal calls

Vyper is a Pythonic smart contract language for the Ethereum virtual machine. Prior to version 0.3.8, internal calls with default arguments are compiled incorrectly. Depending on the number of arguments provided in the call, the defaults are added not right-to-left, but left-to-right. If the type...

CVE-2023-32059

The CVE-2023-32059 entry describes a vulnerability in Vyper (Pythonic smart contract language for EVM) prior to version 0.3.8. Root cause: internal calls with default arguments are compiled with incorrect ordering, causing defaults to be applied left-to-right instead of right-to-left, and in some...

CVE-2023-32058

CVE-2023-32058 affects the Vyper language (EVM smart contracts). Prior to version 0.3.8, there was a missing overflow check for loop variables when iterating with patterns like for i in range(a, a + N). This could cause the loop variable’s type to overflow. The issue appears specifically in for i...
