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 HTTPS to compromise Oracle Enterprise Manager Base Platform. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of Oracle Enterprise Manager Base Platform. CVSS 3.1 Base Score 8.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/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

This is an unauthenticated remote code execution vulnerability in Oracle Enterprise Manager Base Platform's Metadata Plugin component. Attackers can exploit this via HTTPS with only human interaction required (like clicking a malicious link), potentially achieving complete system compromise including full confidentiality, integrity, and availability impacts.

MitigationApply the latest Oracle Critical Patch Update (CPU) for Oracle Enterprise Manager that addresses this vulnerability. Since the vulnerability requires human interaction, also implement network segmentation and restrict external access to the Enterprise Manager console.

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. Confirm Oracle Enterprise Manager Base Platform is installed
    Locate the Oracle Enterprise Manager installation directory (typically $ORACLE_HOME/em or check running processes for 'emctl' or 'oracle.em.*' services)
    Affected if The software is not present, then not affected
  2. Determine the installed version of Oracle Enterprise Manager Base Platform
    Run 'emctl status agent' or check the Oracle inventory via 'opatch lsinventory' for the Enterprise Manager Base Platform component, or access the Enterprise Manager console and navigate to 'Setup > Manage Cloud > About' to view the version
    Affected if Version equals 13.5.0.0 or 24.1.0.0.0 exactly, then affected
  3. Verify the Metadata Plugin component is configured
    Access Enterprise Manager console, navigate to 'Setup > Extensions > Plugin' or check the plugin deployment status via 'emcli list_plugins' command-line tool
    Affected if The Metadata Plugin is deployed and active, then potentially affected
  4. Check if HTTPS listener is exposed on network interfaces
    Review the Oracle Enterprise Manager listener configuration (typically in 'listener.ora' or via 'lsnrctl status') and verify which network interfaces the OMS (Oracle Management Service) is bound to
    Affected if The EM console is accessible via HTTPS from untrusted networks, then exposed and potentially affected
  5. Review access logs for suspicious requests to Metadata Plugin endpoints
    Examine EM security logs (located in $ORACLE_HOME/em/EMGC_OracleDB/sysman/log/) for unusual POST requests to Metadata Plugin URLs or unexpected authentication attempts
    Affected if Anomalous requests targeting Metadata Plugin are found, then may indicate exploitation attempts

You are affected if Oracle Enterprise Manager Base Platform versions 13.5.0.0 or 24.1.0.0.0 are installed with the Metadata Plugin enabled and the HTTPS interface is network-accessible.
