Proof of Concept Method: Calculation: Factory: Here in factory user can add tokens with scale from 6 to 18. Tools Used Static analytics Code reading Recommended Mitigation Steps...

Lendgine contract can be drained through mint() function due to lack of Access Control

Lines of code Vulnerability details Impact Anybody can call the mint function on lendgine.sol and enter any amount of collateral. This allows them to mint any number of tokens to their address for free. Proof of Concept The mint function in lendgine.sol is external with no additional modifiers or...

No-check taht amounts are less than reserves

Lines of code Vulnerability details Impact There is no check that the amount for the flashloan is actually available in the contract. It is checked that it should be 0 but not than reserves. Eventually, the function will revert because the funds are not there and the funds are not in the contract...

The LiquidityManager.pairMintCallback() might be exploited to steal funding from another user when the factory contract is compromised.

Lines of code Vulnerability details Impact Detailed description of the impact of this finding. The LiquidityManager.pairMintCallback might be exploited to steal funding from another user due to three issues: 1. LiquidityManager.pairMintCallback is a callback function for the addLiquidity, which...

A malicious early user/attacker can manipulate the share price to take an unfair share of future users' deposits

Lines of code Vulnerability details Impact A malicious early user/attacker can manipulate the share price to take an unfair share of future users' deposits. The first minter can manipulate the supply of LP tokens and baseToken-fractional ratio, hindering small liquidity providers from interacting...

Anyone can withdraw contract funds

Lines of code Vulnerability details Impact There is a critical impact that an attacker could drain the entire eth balance of the contract by calling this refundETH function which lacks a modifier. The funds will go always to the caller of the function. Proof of Concept It is not a complex attack ...

Unchecked Return Values in SwapHelper.swap.

Lines of code Vulnerability details Impact SafeTransferLib.safeTransfertokenIn, msg.sender, amount0Delta 0 ? uint256amount0Delta : uint256amount1Delta; If the pool does not have enough liquidity, the UniswapV2Library functions will return a failure, but the SwapHelper.swap function does not...

Fee on transfer tokens will not behave as expected

Lines of code Vulnerability details Impact In Numoen, it does not specifically restrict the type of ERC20 collateral used for borrowing. If fee on transfer tokens is/are entailed, it will specifically make mint revert in Lendgine.sol when checking if balanceAfter balanceBefore + collateral. Proof...

Lack of slippage protection when swapping on Uniswap v2/v3

Lines of code Vulnerability details Impact Lack of slippage protection when swapping on Uniswap v2/v3. It'll create the potential to be sandwiched by MEV bots and result in user loss. Proof of Concept In the LendgineRouter.mint function, the contract would swap all the token0 to token1 in...

Unchecked that the to address is nto the address of the tokens

Lines of code Vulnerability details Impact In the swap function, it is unchecked that the to address is not the address of the tokens. This will not lead to a loss of funds because the flashloan will actually revert, but sanity checks like this one should be made following for instance uniswap...
