Attack-Flow Graph

Executive Summary

This is a denial-of-service vulnerability in Oracle Coherence, a middleware product. An unauthenticated attacker can exploit it remotely via TCP to crash or hang the service repeatedly, causing complete downtime.

Detection Guidance

To detect this vulnerability, check if Oracle Coherence versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, or 15.1.1.0.0 are running on your system. Use commands like 'ps -ef | grep coherence' or 'netstat -tulnp | grep <coherence_port>' to identify active instances. Monitor network traffic for unexpected TCP connections to Coherence ports.

Impact Analysis

If you use affected Oracle Coherence versions, an attacker could disrupt your system by making it unavailable. This leads to service outages, data unavailability, and potential business disruptions.

Compliance Impact

This vulnerability causes denial-of-service (DoS) conditions in Oracle Coherence, leading to system unavailability. Such disruptions may violate compliance requirements for availability in standards like GDPR (data processing continuity) and HIPAA (access to critical health data).

Mitigation Strategies

Apply the latest security patches from Oracle for affected Oracle Coherence versions (12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, 15.1.1.0.0). If patches are unavailable, consider isolating the vulnerable systems from untrusted networks or disabling the Oracle Coherence service until updates are applied.
