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: Target Management). Supported versions that are affected are 13.5 and 24.1. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Enterprise Manager Base Platform. 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 9.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/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 · moderate confidence

A critical vulnerability in Oracle Enterprise Manager Base Platform's Target Management component allows a low-privileged attacker with network access via HTTP to achieve complete takeover of the affected system. The CVSS 9.9 score indicates trivial exploitability combined with maximum confidentiality, integrity, and availability impact, with scope changes potentially affecting additional products beyond the base platform.

MitigationApply Oracle's Critical Patch Update for the affected versions (13.5 and 24.1) immediately; until patched, restrict network access to Oracle Enterprise Manager management interfaces and monitor for indicators of compromise.

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
    Locate the Oracle Enterprise Manager installation directory or running services. Common paths include $ORACLE_HOME/em or check for 'Oracle Enterprise Manager' processes running on the system.
    Affected if Oracle Enterprise Manager Base Platform is not installed on the system (not affected). If found, proceed to version check.
  2. Verify installed version against affected releases
    Retrieve the installed version of Oracle Enterprise Manager Base Platform. Check the version string against the affected versions 13.5.0.0 and 24.1.0.0.0 specifically.
    Affected if The installed version exactly matches 13.5.0.0 or 24.1.0.0.0 - these are the confirmed affected versions per the CVE.
  3. Confirm Target Management component is configured
    Determine whether the Target Management component is enabled or configured in the Enterprise Manager environment. This component is part of the base platform and handles discovery and monitoring of targets.
    Affected if The Target Management component is present and configured - this is required for the vulnerability to be exploitable.
  4. Assess network accessibility of HTTP management interface
    Check if the Oracle Enterprise Manager management console (typically ports 7800-7803, 5500, or 1158) is exposed to network access. Review firewall rules and listener configurations.
    Affected if The HTTP-based management interface is network-accessible from untrusted networks - the CVE specifies network access via HTTP as the attack vector.
  5. Review access controls for low-privileged users
    Audit user accounts and roles in Oracle Enterprise Manager. Determine if low-privileged accounts exist that could potentially exploit this vulnerability.
    Affected if Low-privileged user accounts with network access exist in the system - the CVE specifies a low-privileged attacker can achieve complete takeover.

The environment is affected if Oracle Enterprise Manager Base Platform versions 13.5.0.0 or 24.1.0.0.0 are installed AND the Target Management component is configured AND the HTTP management interface is network-accessible to a low-privileged user.
