Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Vulnerability in the Oracle Coherence product of Oracle Fusion Middleware (component: Core). Supported versions that are affected are 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Coherence. While the vulnerability is in Oracle Coherence, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle Coherence. CVSS 3.1 Base Score 10.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Critical unauthenticated remote code execution vulnerability in Oracle Coherence Core component allows attackers with network access via HTTP to completely takeover affected Coherence instances. The CVSS 10.0 score reflects complete confidentiality, integrity, and availability compromise with scope change enabling impact to additional products in the environment.

MitigationApply Oracle's available security patches for versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0 immediately; until patched, restrict network access to Coherence HTTP endpoints to trusted sources only.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Oracle Coherence installation and version
    Locate Coherence installation directory and check version files such as coherence.jar manifest, or run 'java -jar coherence.jar -version' if available. Also check Oracle inventory files if installed via Oracle Fusion Middleware.
    Affected if The installed version matches 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, or 15.1.1.0.0 exactly.
  2. Confirm Coherence HTTP endpoint is exposed
    Inspect Coherence configuration files such as tangosol-coherence.xml, coherence-cache-config.xml, or web.xml for HTTP servlet or REST endpoint configurations. Check if a web listener or HTTP server is bound to a network interface.
    Affected if HTTP/REST endpoints are enabled and bound to an accessible network interface, allowing external HTTP requests.
  3. Verify network accessibility of Coherence ports
    Use 'netstat -an' or 'ss -tlnp' to list listening ports. Identify ports typically used by Coherence HTTP (common defaults include 20000-20050 range or configured HTTP ports). Confirm whether these ports accept connections from untrusted networks.
    Affected if Coherence HTTP ports are listening on interfaces accessible from untrusted networks.
  4. Check for presence of vulnerable Coherence core component
    Examine the classpath or lib directories for coherence-core.jar or similar Coherence core library files. Review deployment descriptors to confirm the Coherence Core component is deployed and active.
    Affected if The Coherence Core component is deployed and actively running.

You are affected if Oracle Coherence version 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, or 15.1.1.0.0 is running with HTTP endpoints exposed to network access.
