Attack-Flow Graph

Executive Summary

This is a vulnerability in Oracle Coherence, a middleware product. It allows unauthenticated attackers with network access to cause a denial of service (DOS) or crash the system. It may also permit unauthorized data modifications.

Detection Guidance

Detecting this vulnerability requires checking for Oracle Coherence instances running vulnerable versions (12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, 15.1.1.0.0) on your network. Use network scanning tools like Nmap to identify open TCP ports typically used by Coherence (default 7574, 8088, etc). Check application logs for unusual activity or crashes in Coherence services.

Impact Analysis

If exploited, it could lead to system crashes, data corruption, or unauthorized access to sensitive information. This disrupts operations and may cause downtime.

Compliance Impact

This vulnerability could impact compliance with GDPR and HIPAA due to unauthorized data access and denial-of-service risks. Unauthorized updates or deletions of data may violate GDPR's integrity requirements and HIPAA's safeguards for protected health information. The denial-of-service potential also threatens availability, a key requirement under both regulations.

Mitigation Strategies

Apply the latest security patches from Oracle for affected Coherence versions. If patches are unavailable, restrict network access to TCP ports used by Oracle Coherence and monitor for unusual activity.
