Attack-Flow Graph

Executive Summary

This is a vulnerability in Oracle Coherence, a middleware product. It allows an unauthenticated attacker with network access via TLS to potentially access sensitive data. The attack requires network access but no user interaction. Successful exploitation could lead to unauthorized access to critical or all accessible data in Oracle Coherence.

Detection Guidance

This CVE describes a vulnerability in Oracle Coherence that allows unauthenticated network access via TLS. Detection requires checking if your system runs affected versions (12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, or 15.1.1.0.0). Use commands like 'java -jar coherence.jar -version' or check Oracle's documentation for version-specific commands. Network scanning tools like Nmap may identify open TLS ports used by Oracle Coherence.

Impact Analysis

If you use affected versions of Oracle Coherence (12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, or 15.1.1.0.0), an attacker could gain access to sensitive data stored or processed by the system. This may include confidential business or user information, depending on what the Coherence instance handles.

Compliance Impact

This vulnerability could lead to unauthorized data access, violating confidentiality requirements in GDPR and HIPAA. Organizations using affected Oracle Coherence versions may face compliance violations, potential fines, and reputational damage if sensitive data is exposed due to this flaw.

Mitigation Strategies

Apply the latest Oracle Coherence patches immediately as they become available. Ensure TLS is properly configured and restrict network access to Oracle Coherence ports. Monitor for unusual data access patterns or unauthorized connections.
