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 Enterprise Manager Base Platform product of Oracle Enterprise Manager (component: Metadata Plugin). Supported versions that are affected are 13.5 and 24.1. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Enterprise Manager Base Platform. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Enterprise Manager Base Platform, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle Enterprise Manager Base Platform. CVSS 3.1 Base Score 9.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/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

A critical vulnerability exists in the Metadata Plugin component of Oracle Enterprise Manager Base Platform (versions 13.5 and 24.1). The flaw is exploitable via HTTP without authentication but requires human interaction, enabling a remote attacker to achieve complete compromise of the enterprise management platform.

MitigationApply the Oracle Critical Patch Update for the affected versions (13.5 and 24.1) as soon as possible; until then, restrict network access to Oracle Enterprise Manager interfaces and monitor for suspicious HTTP activity.

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 Enterprise Manager installation
    Check for Oracle Enterprise Manager Base Platform installation by looking for the 'emctl' command or the Oracle EM console accessible on common ports (e.g., 7788, 1158, 5500). Run 'emctl status' or check Oracle inventory for installed products.
    Affected if Oracle Enterprise Manager Base Platform is installed and running
  2. Verify installed version
    Run 'emctl version' or check the Oracle Enterprise Manager console for the exact version number. Compare against affected versions 13.5.0.0 and 24.1.0.0.0.
    Affected if Version matches exactly 13.5.0.0 or 24.1.0.0.0
  3. Confirm Metadata Plugin is accessible
    Check if the Metadata Plugin component is deployed and accessible via HTTP/HTTPS endpoints. Review the Oracle EM console for plugin status or check for Metadata Plugin-related WAR files in the deployment directory.
    Affected if Metadata Plugin is enabled and exposed via HTTP interface
  4. Assess network exposure
    Determine if the Oracle Enterprise Manager console is exposed to untrusted networks or the internet. Check firewall rules, load balancer configurations, and access control lists around the EM web interface.
    Affected if The EM console is reachable from untrusted networks without proper access restrictions

A user is affected if they run Oracle Enterprise Manager Base Platform versions 13.5.0.0 or 24.1.0.0.0 with the Metadata Plugin accessible over network without restriction.
