Attack-Flow Graph

Executive Summary

This is a vulnerability in Oracle Coherence, a middleware product. It allows a low-privileged attacker with local system access to read some data that they should not be able to access. The attack is difficult to perform and requires the attacker to already have logon access to the system where Oracle Coherence runs.

Detection Guidance

Detection of this vulnerability requires checking for Oracle Coherence version 15.1.1.0.0 and verifying if low-privileged users can access sensitive data. Review logs for unauthorized read attempts and ensure proper access controls are enforced.

Impact Analysis

If you use Oracle Coherence version 15.1.1.0.0, an attacker with local access could read sensitive data stored or processed by Oracle Coherence. This could lead to unauthorized data exposure, potentially affecting confidentiality of information.

Compliance Impact

This vulnerability could lead to unauthorized data access, which may violate compliance requirements under GDPR, HIPAA, or other regulations that mandate strict data protection and access controls. Organizations using affected versions may face compliance risks due to potential data breaches.

Mitigation Strategies

Apply the latest Oracle Coherence patch to upgrade to a non-vulnerable version. Restrict logon privileges to only necessary users and monitor data access patterns for anomalies.
