CVE-2022-35961 ECDSA signature malleability in OpenZeppelin Contracts

OpenZeppelin Contracts is a library for secure smart contract development. The functions ECDSA.recover and ECDSA.tryRecover are vulnerable to a kind of signature malleability due to accepting EIP-2098 compact signatures in addition to the traditional 65 byte signature format. This is only an issu...

CVE-2022-35961

OpenZeppelin Contracts is a library for secure smart contract development. The functions "ECDSA.recover" and "ECDSA.tryRecover" are vulnerable to a kind of signature malleability due to accepting EIP-2098 compact signatures in addition to the traditional 65 byte signature format. This is only an...

CVE-2022-35961

OpenZeppelin Contracts (ECDSA.recover and ECDSA.tryRecover) suffer signature malleability due to acceptance of EIP-2098 compact signatures in the single-bytes variants (not when using r, v, s or r, vs). This could allow a reused/double-submitted signature to bypass replay protection in contracts ...

Inadequate transferOwnership function prevents new owner from accessing funds

Lines of code Vulnerability details Description There are two sources of truth for identifying the account that owns a given MIMOProxy: 1. MIMOProxy.owner 2. MIMOProxyRegistry.getCurrentProxyaddress The first source of truth is only used within the proxy contract itself, and the second source of...

Lack of storage gap for upgradable contracts

Lines of code Vulnerability details Impact Safe usage of upgradable contract should include a storage gap to allow the addition of new state. OpenZeppelin docs Proof of Concept The following contracts on the project are using upgradable contracts from OpenZeppelin. File: contracts/Community.sol...

Malicious Package

Overview subnet-evm-contracts is a malicious package. The package's name is based on existing repositories, namespaces, or components used by popular companies in an effort to trick employees into downloading it, also known as 'dependency confusion'. Therefore, you're only vulnerable if this...

No Storage Gap for Upgradeable Contract Might Lead to Storage Slot Collision

Lines of code Vulnerability details Impact For upgradeable contracts, there must be storage gap to "allow developers to freely add new state variables in the future without compromising the storage compatibility with existing deployments" quote OpenZeppelin. Otherwise it may be very difficult to...

Business Logic Flaws

OpenZeppelin Contracts has business logic flaws. The vulnerability exists due to a lack of sanitization between cross chains allowing contracts using Arbitrum L2, CrossChainEnabledArbitrumL2 or LibArbitrumL2 to be classified as direct interactions of externally owned accounts EOAs even though the...

OpenZeppelin Contracts has business logic flaw. The vulnerability exists due to a lack of sanitization of past quorum allowing it to be executable when a new quorum meets the smart contract's requirement...

Attacker can empty vaults

Lines of code Vulnerability details Impact Both MIMOEmptyVault and MIMOLeverage contracts share same signature/definition, an attacker can gain control of EmptyVault contract, issue a flash loan, and empty the vaults. Proof of Concept See the test below. In below test, EmptyVault contract is...

CVE-2022-35916

OpenZeppelin Contracts is a library for secure smart contract development. Contracts using the cross chain utilities for Arbitrum L2, CrossChainEnabledArbitrumL2 or LibArbitrumL2, will classify direct interactions of externally owned accounts EOAs as cross chain calls, even though they are not...

CVE-2022-35915

OpenZeppelin Contracts is a library for secure smart contract development. The target contract of an EIP-165 supportsInterface query can cause unbounded gas consumption by returning a lot of data, while it is generally assumed that this operation has a bounded cost. The issue has been fixed in...
