dbcve analysis · high confidence

Vulnerability in Oracle E-Business Suite Complex Maintenance, Repair and Overhaul (Internal Operations component) allows a low-privileged attacker with network access via HTTP to achieve complete system takeover. The vulnerability is marked as difficult to exploit but can result in high impact across confidentiality, integrity, and availability. Affected versions span 12.2.3 through 12.2.15.

MitigationApply the relevant Oracle Critical Patch Update (CPU) for this vulnerability and restrict network access to the Internal Operations module to trusted users only. Ensure least-privilege principles are enforced for user accounts accessing this component.

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 E-Business Suite installation and version
    Query the Oracle database or check the application tier for the E-Business Suite version. Use SQL query: SELECT release_name FROM apps.fnd_product_groups; or check the INSTALL_TOP/Oracle Applications directory for release information.
    Affected if The installed version is between 12.2.3 and 12.2.15 inclusive.
  2. Confirm Complex Maintenance Repair and Overhaul module is installed
    Check if the Complex Maintenance, Repair and Overhaul (CMRO) module is present in the E-Business Suite installation. Query: SELECT application_id, application_name FROM apps.fnd_application WHERE application_name LIKE '%Complex Maintenance%'; or check the module registration in Oracle Application Manager.
    Affected if The CMRO module is registered and installed in the E-Business Suite.
  3. Determine if Internal Operations component is enabled
    Verify that the Internal Operations sub-component of CMRO is enabled. Check the Oracle Responsibility definition for the Internal Operations responsibility: Query fnd_responsibility or check through Oracle Application Manager > Security > Responsibility.
    Affected if The Internal Operations responsibility is assigned and accessible to users.
  4. Verify network accessibility of the module
    Check if the Internal Operations module is accessible over HTTP/HTTPS from the network. Review web listener configuration, Oracle HTTP Server settings, and firewall rules. Test connectivity to the module URL path typically under /OA_HTML/ or the CMRO web interfaces.
    Affected if The Internal Operations module is exposed to network access beyond trusted internal users.
  5. Review user privilege assignments
    Examine which low-privileged user accounts have access to the Internal Operations responsibility. Query fnd_userresponsibility or check through Oracle User Management to list users assigned the Internal Operations role.
    Affected if Low-privileged or non-administrative user accounts have access to the Internal Operations module.

You are affected if Oracle E-Business Suite version 12.2.3 through 12.2.15 is installed with the Complex Maintenance Repair and Overhaul module and its Internal Operations component is enabled and accessible over the network to low-privileged users.
