CVE-2022-39354 : Exploit Details and Defense Strategies

This article provides insights into CVE-2022-39354, focusing on the vulnerability in the evm container that can lead to incorrect state transitions due to an incorrect is_static parameter for custom stateful precompiles.

Understanding CVE-2022-39354

This section delves into the details of the CVE-2022-39354 vulnerability affecting the Rust implementation of Ethereum Virtual Machine (EVM).

What is CVE-2022-39354?

CVE-2022-39354 highlights an issue in the evm container where the

is_static

parameter is incorrectly set for custom stateful precompiles, potentially causing incorrect state transitions.

The Impact of CVE-2022-39354

The vulnerability in version < 0.36.0 of the evm container can lead to erroneous state changes for affected custom precompiles, impacting the integrity of operations.

Technical Details of CVE-2022-39354

In this section, we explore the technical aspects related to CVE-2022-39354, including the vulnerability description, affected systems and versions, and the exploitation mechanism.

Vulnerability Description

Prior to version 0.36.0 of the evm container, the

is_static

parameter was inaccurately set, affecting custom precompiles that rely on this parameter and potentially causing incorrect state changes.

Affected Systems and Versions

The vulnerability impacts versions prior to 0.36.0 of the Rust blockchain evm container, specifically affecting custom stateful precompiles utilizing the

is_static

parameter.

Exploitation Mechanism

The vulnerability can be exploited by malicious actors to trigger incorrect state transitions in custom precompiles that utilize the flawed

is_static

parameter implementation.

Mitigation and Prevention

This section focuses on the steps to mitigate the risks posed by CVE-2022-39354, highlighting immediate actions and long-term security practices to ensure system integrity.

Immediate Steps to Take

Users are advised to update their evm container to version 0.36.0 or newer to apply the patch that addresses the incorrect

is_static

parameter issue.

Long-Term Security Practices
