Attack-Flow Graph

Executive Summary

This is a vulnerability in Oracle Fusion Middleware's Helidon product, specifically in the LRA component. It affects versions 4.0.0 to 4.5.5. The issue allows an unauthenticated attacker to remotely access some data through HTTP requests. The attack is difficult to perform but can lead to unauthorized read access to a subset of Helidon data.

Detection Guidance

This vulnerability can be detected by checking the version of Helidon running on your system. If you are running Helidon versions 4.0.0 to 4.5.5, your system is vulnerable. Use commands like 'java -jar helidon.jar --version' or check your application's dependency files (e.g., pom.xml for Maven) to verify the Helidon version.

Impact Analysis

If you use the affected Helidon versions, an attacker could exploit this to read some data from your system without authentication. This could expose sensitive information, though the scope is limited to a subset of accessible data.

Compliance Impact

This vulnerability allows unauthorized read access to a subset of Helidon accessible data, which could potentially expose sensitive information. This may impact compliance with GDPR (data confidentiality requirements) and HIPAA (protected health information safeguards) if the exposed data includes personal or health-related information.

Mitigation Strategies

Upgrade Helidon to a version later than 4.5.5, as the vulnerability affects versions 4.0.0-4.5.5. Apply the latest security patches from Oracle to address the issue.
