CVE-2023-30610 : What You Need to Know

AWS SDK for Rust will log AWS credentials when TRACE-level logging is enabled for request sending.

Understanding CVE-2023-30610

This vulnerability affects aws-sigv4, a rust library for low-level request signing in the AWS cloud platform.

What is CVE-2023-30610?

The

aws_sigv4::SigningParams

struct in AWS SDK for Rust has a

Debug

implementation that exposes sensitive AWS credentials when debug-formatted. Enabling TRACE-level logging for request sending can reveal these credentials in plaintext in the logs.

The Impact of CVE-2023-30610

All users of the AWS SDK for Rust who have enabled TRACE-level logging are at risk of exposing their AWS access key, AWS secret key, and security token. This poses a high confidentiality impact on affected systems.

Technical Details of CVE-2023-30610

This section provides detailed technical information about the vulnerability.

Vulnerability Description

The issue arises from the debug formatting of the

SigningParams

struct, which unintentionally includes sensitive information. Enabling TRACE-level logging results in the exposure of AWS credentials in plaintext in the logs.

Affected Systems and Versions

Multiple versions of aws-sdk-rust are affected by this vulnerability, ranging from version 0.2.0 to 0.55.0. Users of these versions who have enabled TRACE-level logging are at risk.

Exploitation Mechanism

Exploiting this vulnerability requires access to the logged information when TRACE-level logging is enabled. Attackers with access to these logs can potentially retrieve AWS credentials.

Mitigation and Prevention

Here are the steps to mitigate the risks posed by CVE-2023-30610.

Immediate Steps to Take

Upgrade to the latest patched version of aws-sdk-rust to fix the credential exposure issue.
Disable TRACE-level logging for AWS Rust SDK crates if immediate upgrade is not feasible.

Long-Term Security Practices

Regularly monitor and audit logging configurations and levels to prevent inadvertent exposure of sensitive information.
Follow AWS security best practices and guidelines for secure application development and deployment.

Patching and Updates

Always stay updated with the latest releases and security advisories from AWS to maintain a secure development environment.
