Proxy's logic contract relies on code in the constructor

Lines of code 122, 50, 25, 67, 98, 67, 22 Vulnerability details Impact Logic contracts cannot rely on code in their constructors, because proxy contracts do not re-execute the logic contract's constructor - only its initializer. Move all code in the constructor to the initializer function. File:...

CVE-2023-42449

Hydra is the two-layer scalability solution for Cardano. Prior to version 0.13.0, it is possible for a malicious head initializer to extract one or more PTs for the head they are initializing due to incorrect data validation logic in the head token minting policy which then results in an flawed...

Design/Logic Flaw

CVE-2023-42449 Malicious head initialiser can extract PTs from control of Hydra scripts, leading to locked participant commits or spoofed commits

Hydra is the two-layer scalability solution for Cardano. Prior to version 0.13.0, it is possible for a malicious head initializer to extract one or more PTs for the head they are initializing due to incorrect data validation logic in the head token minting policy which then results in an flawed...

CVE-2023-42449

Hydra (Cardano) prior to v0.13.0 has an input validation flaw in the head initialiser that lets a malicious head initialiser extract PTs for the head being initialised, bypassing checks in HeadTokens.hs and off‑chain code. This can enable the attacker to lock other participants’ committed funds (...

The prime Initializer function in prime.sol is marked “virtual”

Lines of code Vulnerability details Impact The prime initializer is responsible for setting the state variables in the prime.sol contract. The deal breaker here is; Use of virtual - If the function in the parent contract is expected to be overridden in its child contracts, it should be declared a...

onlyProxy MODIFIER CAN BE BYPASSED BY A MALICIOUS PROXY CONTRACT AND CAN PUSH THE IMPLEMENTATION CONTRACT INTO AN UNDESIRABLE STATE

Lines of code Vulnerability details Impact The Upgradeable.onlyProxy modifier is used to ensure that a function can only be called by the proxy and can not be directly called in the Upgradeable.sol contract. The onlyProxy modifier implementation is as follows: modifier onlyProxy // Prevent setup...

Anyone Can selfdestruct The VaultProxy Contract.

Lines of code Vulnerability details Vulnerability Details -Since the initialise function is missing initializer modifier as it's inteded to be not protected as per ETHx smart contract functions documentation , And Since VaultFactory contract doesn't initialize the VaultProxy upon its initializati...

SUSE CVE-2010-3708

The serialization implementation in JBoss Drools in Red Hat JBoss Enterprise Application Platform aka JBoss EAP or JBEAP 4.3 before 4.3.0.CP09 and JBoss Enterprise SOA Platform 4.2 and 4.3 supports the embedding of class files, which allows remote attackers to execute arbitrary code via a crafted...

Spring Modulith 0.3 released

Hot on the heels of Spring Boot 3.0.2, I am excited to announce the 0.3 release of Spring Modulith. The release is packed with improvements. We have tweaked a couple of things that might require your attention and a couple of adapting changes to your code. The most notable changes are: GH-114 – W...

Update initializer library to prevent reentrancy during initialization

Lines of code Vulnerability details Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an external initializer function, usually called initialize. It then becomes necessary to protect this initializer function so it can only be called once. The...

Authorization Bypass

OpenZeppelin Contracts is vulnerable to authentication bypass. The vulnerability exists because initializer modifier is not properly handled which allows an attacker to cause reentrancy by executing an external call to an untrusted address...

CVE-2022-39384 OpenZeppelin Contracts initializer reentrancy may lead to double initialization

OpenZeppelin Contracts is a library for secure smart contract development. Before version 4.4.1 but after 3.2.0, initializer functions that are invoked separate from contract creation the most prominent example being minimal proxies may be reentered if they make an untrusted non-view external cal...

Openzeppelin contracts with critical and high vulnerabilities can be installed and used

Lines of code Vulnerability details Impact Currently, @openzeppelin/contracts and @openzeppelin/contracts-upgradeable versions are set as follows. "@openzeppelin/contracts": "^4.1.0", "@openzeppelin/contracts-upgradeable": "^4.1.0", For the specified version, there are some critical and high...

Update initializer modifier to prevent reentrancy during initialization

Lines of code Vulnerability details Impact The solution uses: "@openzeppelin/contracts": "^4.0.0", "@openzeppelin/contracts-upgradeable": "^4.3.2", These dependencies have a known high severity vulnerability: Which makes these contracts vulnerable: contracts/helpers/CryptoPunksHelper.sol: 19:...

[WP-H0] Wrong implementation of EIP712MetaTransaction

Lines of code Vulnerability details 1. EIP712MetaTransaction is a utils contract that intended to be inherited by concrete actual contracts, therefore. it's initializer function should not use the initializer modifier, instead, it should use onlyInitializing modifier. See the implementation of...

Privilege Escalation

openzeppelin/contracts is vulnerable to privilege escalation. The vulnerability exists due to the lack of sanitization in the initializer function which allowed an actor with executor role to escalate privileges...

Improper Initialization in OpenZeppelin

In OpenZeppelin =v4.4.0, initializer functions that are invoked separate from contract creation the most prominent example being minimal proxies may be reentered if they make an untrusted non-view external call. Once an initializer has finished running it can never be re-executed. However, an...
