Contracts are vulnerable to rebasing accounting-related issues

Lines of code Vulnerability details Impact Rebasing tokens are tokens that have each holder's balanceof increase over time. Aave aTokens are an example of such tokens. If rebasing tokens are used, rewards accrue to the contract holding the tokens, and cannot be withdrawn by the original depositor...

Owner will be address(0) because it is not initialized

Lines of code Vulnerability details Impact Owner will be address0 making the functions which use the onlyOwner modifier insolvable Proof of Concept There are contracts in the protocol which use the Ownable from OZ: esLBRBoost.sol, EUSDMiningIncentives.sol, ProtocolRewardsPool.sol,...

Improper Input Validation

@openzeppelin/contracts and @openzeppelin/contracts-upgradeable are vulnerable to Improper Input Validation. If a contract uses multiproofs for verification and the merkle tree processing includes a node with value 0 at depth 1, then the contract may be insecure. Balanced trees with three or fewe...

The broker should not be fully disabled by GnosisTrade.reportViolation

Lines of code Vulnerability details Impact GnosisTrade and DutchTrade are two separate auction systems where the failing of either system should not affect the other one. The current design will have Broker.sol disabled when reportViolation is invoked by GnosisTrade.settle if the auction's cleari...

CVE-2023-34459

OpenZeppelin Contracts (versions 4.7.0–4.9.1) are affected by a multiproof forgery issue when using verifyMultiProof/verifyMultiProofCalldata/processMultiProof/processMultiProofCalldata. If the merkle tree includes a node with value 0 at depth 1 under the root, a adversarial or certain benign tre...

CVE-2023-34459 OpenZeppelin Contracts's MerkleProof multiproofs may allow proving arbitrary leaves for specific trees

OpenZeppelin Contracts is a library for smart contract development. Starting in version 4.7.0 and prior to version 4.9.2, when the verifyMultiProof, verifyMultiProofCalldata, procesprocessMultiProof, or processMultiProofCalldat functions are in use, it is possible to construct merkle trees that...

OpenZeppelin 安全漏洞

OpenZeppelin is a software application. A standard for secure blockchain applications. A security vulnerability exists in OpenZeppelin Contracts version 4.7.0 through versions prior to 4.9.2. No information about this vulnerability is available at this time, so please stay tuned to CNNVD or vendo...

Upgraded Q -> 2 from #66 [1686923855595]

Judge has assessed an item in Issue 66 as 2 risk. The relevant finding follows: L-13 The owner is a single point of failure and a centralization risk Having a single EOA as the only owner of contracts is a large centralization risk and a single point of failure. A single private key may be taken ...

CVE-2023-34449

ink! is an embedded domain specific language to write smart contracts in Rust for blockchains built on the Substrate framework. Starting in version 4.0.0 and prior to version 4.2.1, the return value when using delegate call mechanics, either through CallBuilder::delegate or...

CVE-2023-34449

The CVE-2023-34449 issue affects ink! (Rust-based eDSL for Substrate). Affected versions are 4.0.0 up to, but not including, 4.2.1; the bug arises from incorrect decoding of the return value when using delegate call mechanics via CallBuilder::delegate or ink_env::invoke_contract_delegate. The roo...

expirationPeriod in the strategy contracts is not checked when calling LlamaCore.execute

Lines of code Vulnerability details Impact If executionPeriod is set to an extremely short time or even 0, then all actions can never be executed. Proof of Concept There are 7 states in an Action flow: Active, Canceled, Failed, Approved, Queued, Expired, Executed. Generally, the sequence goes lik...

Arbitrary delegatecalls from LlamaAccount can be used to steal assets

Lines of code Vulnerability details Impact Using delegatecall to call arbitrary contracts is highly dangerous as it can be used to steal assets. An attacker could sneak in a contract that steals all the assets owned by the LlamaAccount contract. Proof of Concept Below is a diff to the existing...

Lack of Event Signature Verification

Lines of code Vulnerability details Impact The functions submitExchangeRateData, submitSDPrice, and submitValidatorStats emit events without verifying the signature of the calling contract. Malicious contracts can exploit this by emitting events with misleading information, potentially deceiving...

Problem with Day values

Lines of code Vulnerability details Impact Detailed description of the impact of this finding. In solidity, block.timestamp makes use of seconds in calculating time but in the highlighted codes, the stated period and their comments was miscalculated. 7200 was referred to as 24 hours and was used...

pause/unpause functionnalities not implemented in many pausable contracts

Lines of code Vulnerability details Impact The following contracts : SocializingPool, StaderOracle, OperatorRewardsCollector and Auction are supposed to be pausable as they all inherit from PausableUpgradeable but they don't implement the external pause/unpause functionalities which means it will...

CVE-2023-34234

OpenZeppelin Contracts is a library for smart contract development. By frontrunning the creation of a proposal, an attacker can become the proposer and gain the ability to cancel it. The attacker can do this repeatedly to try to prevent a proposal from being proposed at all. This impacts the...
