Reappearance of M-02 in SafEth.unstake()

Reappearance of M-02 in SafEth.unstake Description The changes in SafEth.unstake has introduced a new issue parallel to the one present in SfrxEth.withdraw which was reported in M-02: sFrxEth may revert on redeeming non-zero amount, i.e. SafEth.unstake may revert as a consequence of a valid call ...

Mitigation Confirmed for NEW

Note: Issue has not actually been resolved but for some reason I can't get my issues to submit without "Mitigation confirmed no new vulnerabilities detected" checked so I am doing this as a work around Severity High Lines of code Impact Derivative will become broken and all funds lost even if the...

Integer Overflow in Endian Library

Lines of code Vulnerability details Impact An integer overflow can lead to unexpected behavior in a smart contract, potentially causing financial loss or disruption of the contract's intended functionality. Proof of Concept If the input value passed to the function exceeds 64 bits, an integer...

High gas consumption vulnerability due to high merkle tree heights

Lines of code Vulnerability details Impact The issue stems from the utilization of tall trees in numerous merkle trees within the BeaconChainProofs library. This could lead to considerable gas consumption during the creation and verification of such trees. The consequence of this vulnerability is...

High Reentrancy Withdrawals can be frontrun

Lines of code Vulnerability details Impact A reentrancy attack on the withdrawal functions could allow an attacker to drain the contract of all funds by repeatedly calling the functions faster than transactions can complete. By calling completeQueuedWithdrawal and withdrawBeaconChainETH multiple...

isContract() is not a reliable way of checking if the input is an EOA

Lines of code Vulnerability details Impact depositIntoStrategyWithSignature is checking if the msg.sender is EOA or the contract and it is doing it by check isContract which is not right Proof of Concept The isContract check can be passed even though if msg.sender is a smart contract if Function ...

Zero address pauser assignment

Lines of code Vulnerability details Impact By allowing any address to be assigned as the pauser, the StrategyBase contract leaves itself vulnerable to losing critical functionality that controls token transfers in and out. Assigning a zero address would result in no valid pauser, preventing the...

Vulnerability in Keccak Function Used for Equality Check in equals() Function.

Lines of code Vulnerability details Impact The BytesUtils library is using Keccak function to check for equality in the equals function. This is a security concern since the Keccak function is vulnerable to hash collisions, which could allow a malicious user to create an input that matches a...

CVE-2023-30629

Vyper is a Pythonic Smart Contract Language for the ethereum virtual machine. In versions 0.3.1 through 0.3.7, the Vyper compiler generates the wrong bytecode. Any contract that uses the rawcall with revertonfailure=False and maxoutsize=0 receives the wrong response from rawcall. Depending on the...
