code doesn't check that the Uniswap pool is not exist and if attacker creates the uniswap pool before hand with calculatable papr address and underlying address and exact fee amount, then the deployment transaction would fail always

Lines of code Vulnerability details Impact attacker can perform DOS and prevent contract from getting deployed. the address of papr can be calculate by attacker before its deployment and the address of the underlyingUSDC and the fee is known, attacker can create uniswap pool before-hand and cause...

Faulty fee handling in buyAndReduceDebt

Lines of code Vulnerability details Impact When passing fee params to buyAndReduceDebt with swapFeeTo and swapFeeBips, the PaprController will try to send the underlying token on the following line: underlying.transferparams.swapFeeTo, amountIn params.swapFeeBips / BIPSONE; But in a normal state,...

Pair.sol can be manipulated to affect small liquidity providers.

Lines of code Vulnerability details Impact The first minter can manipulate the supply of LP tokens and baseToken-fractional ratio, hindering small liquidity providers from interacting with the pair. A malicious actor can mint 1wei of LP token from a new pair, then proceed to transfer baseToken to...

buyQuote should be rounded up

Lines of code Vulnerability details Impact The buyQuote is not rounded up, which can cause a leak of value, due to the buyQuote being underestimated. Proof of Concept The function Pair.buyQuote does not round up, which can cause the issue described under Impact: function buyQuoteuint256...

Rounding down leads to breakage of the xy curve calculation

Lines of code Vulnerability details Impact When needing to calculate the inputAmount required to receive a certain amount of fractional tokens called outputAmount, we are deriving from the xy = k curve used on the Uniswap V2 protocol. Proof of Concept Some maths: The so-called curve equation is: ...

sellQuote might lead to unexpected reverts when returning zero

Lines of code Vulnerability details Impact the implementation of sellQuote follows the logic of getAmountOut from Uniswap V2 Library. However it doesn't add +1 as the original implementation, this could make the function return zero and lead to reverts. Proof of Concept Tools Used Manual review...

Surplus token after adding liquidity is not refunded to liquidity providers. LP might suffer front-running attack and lose funds.

Lines of code Vulnerability details Impact Function Pair.add receives base token and fractional token from liquidity providers and mint equivalent amount of LP token for them. The amount of LP token be minted is calculate in function addQuote function addQuoteuint256 baseTokenAmount, uint256...

Attacker can manipulate low TVL Uniswap V3 pool to borrow and swap to make Lending Pool in loss.

Lines of code Vulnerability details Impact In Paraspace protocol, any Uniswap V3 position that are consist of ERC20 tokens that Paraspace support can be used as collateral to borrow funds from Paraspace pool. The value of the Uniswap V3 position will be sum of value of ERC20 tokens in it. functio...

Upgraded Q -> M from #38 [1670234424045]

Judge has assessed an item in Issue 38 as M risk. The relevant finding follows: L2. Pool selection for the compound is not restricted Compound function of AutoPxGmx contract is public and available for everyone. An attacker can create a custom pool with a higher fee value currently, on tests it...

PT-2023-15616 · Uniswap · Uniswap Universal Router

Name of the Vulnerable Software and Affected Versions: Uniswap Universal Router versions prior to 1.1.0 Description: The issue concerns the mishandling of reentrancy in the Uniswap Universal Router, which could have allowed the theft of funds. Recommendations: For versions prior to 1.1.0, update ...

The compound() function is used with a fixed amountOutMinimum value

Lines of code Vulnerability details Impact The compound function helps to swap the gmxBaseReward ether for GMX tokens then the GMX tokens are deposited for pxGMX. In the swap function the amountOutMinimum helps to put the minimum value that is expected for the swap. The fixed amountOutMInimum...

compound could be used by uniswap stakers to maximize fees for AutoPxGmx users

Lines of code Vulnerability details Impact Anyone can call AutoPxGmx::compound. Hence a staker in the 10000 1% fee uniswap pool can call compound with that pool and take a larger fee from AutoPxGmx users maximizing their gains and griefing users. Proof of Concept fee chooses which uniswap pool to...

Uniswap V3 swaps are vulnerable to a sandwich attack

Lines of code Vulnerability details Impact As the amountOutMinimum is always hardcoded with 1 in the AutoPxGmx, then the Uniswap V3 swap is vulnerable to a frontrun / sandwich attack. Proof of Concept Even though the amountOutMinimum may never be 0 because it is prevented against it: if...

Functions like AutoPxGmx.withdraw and AutoPxGmx.redeem do not provide effective slippage control

Lines of code Vulnerability details Impact As shown below, calling the AutoPxGmx.withdraw and AutoPxGmx.redeem functions would execute compoundpoolFee, 1, 0, true, which uses the hardcoded 1 as the amountOutMinimum input of the AutoPxGmx.compound function to further call the...

AutoPxGmx.compound function can be directly called with a fee input value that is not the configured Uniswap pool fee

Lines of code Vulnerability details Impact Calling the following AutoPxGmx.withdraw and AutoPxGmx.redeem functions would execute compoundpoolFee, 1, 0, true, which uses the configured Uniswap pool fee as the fee input of the AutoPxGmx.compound function below to further call the...

computeAddress does not follow the standard procedure to compute the address. The contract can not create pool for some pairs due to hash collision

Lines of code Vulnerability details Impact Poor source of randomness, an attacker can easily decipher the computed address. The contract can be easily tricked. This can cause hash collision, due to this, for some pairs, the contract can not create pool. Proof of Concept AlgebraFactory.solL123 : T...
