A buffer overflow and null pointer dereference flaw was found in the Linux kernel's Secure Encrypted Virtualization SEV implementation for AMD functionality. This issue occurs when a user in SEV guest VM accesses MMIO registers, which could allow a local user to crash the system or escalate their...

Risky use of Static Address

Lines of code Vulnerability details Impact We see a native token address used as 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE which is fine to use to denote native ether, but if this contract were to be deployed in another chain like Polygon, this would cause inconsistency issues. Proof of Concept...

stakers can withraw reward without waiting the vesting period

Lines of code Vulnerability details Impact stakers can frontrun a reward giving transaction by monitoring the mempool for the function transferInRewards, and stake before it, and then unstake after to get rewards, if the cooldown is off. Proof of Concept imagine a scenario where the cooldown peri...

Shares Manipulation DoS Vulnerability in StakedUSDe

Lines of code Vulnerability details Impact The StakedUSDe contract is vulnerable to manipulation by a malicious actor, leading to a permanent interruption of operations through a Denial-of-Service DoS attack. This vulnerability also impacts StakedUSDeV2 due to its inheritance of the StakedUSDe...

Compromised minter can change route to misdirect user funds

Lines of code Vulnerability details Impact The current security assumption revolves around the compromise of a minter, wherein they mint 200k USDe tokens for themselves and subsequently redeem them within the contract. Under this assumption, as long as the gatekeeper key remains secure, the minte...

There is no check for collateral token in mint matches same in withdraw

Lines of code Vulnerability details Impact While we understand that usde is the base token here, we see that on minting used token you would need to transfer some tokens to the contract and get some used minted to you and on redemption get usde burnt to get a token sent back to you. The implicati...

replay exploitation in StakedUSDeV2's unstake function

Lines of code Vulnerability details Impact The vulnerability in the unstake function of the StakedUSDeV2 contract allows the receiver to claim assets without considering the specific round from which they should receive the assets. The receiver can claim assets from a different round than intende...

Tokens having Fee-On-Transfer are not considered which will make the protocol in retaining less value than expected.

Lines of code Vulnerability details Impact The balance of the custodian Addresses will be smaller than what is expected, making the protocol fail to maintain the delta neutral position. Proof of Concept The function EthenaMinting.sol/transferCollateral is sending the tokens using safeTransferFrom...

Wrong estimation of acceptable risk of the protocol losses

Lines of code Vulnerability details Impact The protocol losses in case compromised MINTERS or REDEEMERS can be higher than expected due to the GATEKEEPER suppression. Attacker can frontrun the GATEKEEPER and fill block limit with own transactions while it is profitable. Average losses can be more...

Temporary DOS attack on all the users minting and redeeming.

Lines of code Vulnerability details Impact The users redeeming and minting using EthenaMinting.sol can be DOS'd temporarily for some blocks by an old user having many tokens staked. Proof of Concept The old user having a high staked amount can easily get the order to redeem and mint with the USDe...

Vulnerability in in rescueTokens and _beforeTokenTransfer Functions Allows Self-Transfer of ERC20 Tokens

Lines of code Vulnerability details Impact The rescueTokens function and the beforeTokenTransfer hook in the provided Solidity contract lack checks to ensure that the destination address is not the same as the sender from. This oversight can result in tokens being transferred to the same address,...

Wrong vest logic

Lines of code Vulnerability details Impact The judgment on line 90 results in that the interval between two transferInRewards must be greater than or equal to 8 hours, otherwise it will be reverted. Proof of Concept Tools Used Recommended Mitigation Steps Delete 90 lines of judgment. Assessed typ...

Staking functionality temporary blocking due to lack of address zero check

Lines of code Vulnerability details Impact Though lack of zero check issue for the addToBlacklist function is already at the automated findings output, I suppose it is necessary to show the importance of this check here. In case of accidental or malicious the BLACKLISTMANAGERROLE behavior the...

Reentrancy opened for any contract that calls the withdraw function

Lines of code Vulnerability details Impact Reentrancy opened for any contract that calls the withdraw function in the stakedUSDeV2.sol which would drain of ether. Proof of Concept function withdrawaddress to, uint256 amount external onlyStakingVault USDE.transferto, amount; In this scenario, the...

hardcoded route ratio might hcause verify route return false continously instead use >=

Lines of code Vulnerability details Impact hardcoded rout ratio might cause verify route to return false continuously the verifyroute in ethenaminting.sol is an if that checks whether the route ratio is 10000 or not and the ratio is going to be somewhere around that but what if it actually up wit...

Temporary DOS attack on users minting and redeeming big amount using EthenaMinting.sol

Lines of code Vulnerability details Impact The users redeeming and minting using EthenaMinting.sol with a large amount can be vulnerable to DOS attack. Proof of Concept There is a limit on the max amount to redeem and mint in a block. This can be crucial to the users that are minting or redeeming...

Rewards transfer In fail

Lines of code Vulnerability details Impact the rewards transfer in will fail when current VESTINGPERIOD is not finished. Proof of Concept "function getUnvestedAmount public view returns uint256" is used to calculate the rest rewards in current VESTINGPERIOD. if the period is finished, the result...
