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 Complex Maintenance, Repair, and Overhaul product of Oracle E-Business Suite (component: LOV). Supported versions that are affected are 12.2.3-12.2.13. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Complex Maintenance, Repair, and Overhaul. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Complex Maintenance, Repair, and Overhaul, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Complex Maintenance, Repair, and Overhaul accessible data as well as unauthorized read access to a subset of Oracle Complex Maintenance, Repair, and Overhaul accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

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

Unauthenticated HTTP vulnerability in the LOV (List of Values) component of Oracle E-Business Suite's Complex Maintenance, Repair, and Overhaul module allows remote attackers to read or modify some data without credentials, but requires human interaction (e.g., tricking a user into clicking a malicious link). The scope change indicates attacks may impact additional products beyond the directly affected module.

MitigationApply Oracle Critical Patch Update (CPU) for April 2024 that addresses CVE-2024-21042. Until patched, restrict network access to the E-Business Suite web interfaces and consider deploying a WAF to filter malicious requests.

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 E-Business Suite is installed
    Look for Oracle E-Business Suite web tier components (Oracle HTTP Server, Oracle WebLogic Server) running or check for E-Business Suite installation directories such as $OA_HTML, $FND_TOP, or the Oracle Application Server directories.
    Affected if Oracle E-Business Suite web interfaces are accessible on the network
  2. Identify the Complex Maintenance Repair And Overhaul (CMRO) module version
    Query the database using SQL: SELECT patch_level FROM applsys.fnd_product_installations WHERE patch_level LIKE '%CMRO%'; or check the Oracle Applications Manager (OAM) interface for the installed version of the Complex Maintenance, Repair, and Overhaul module.
    Affected if The installed version falls within 12.2.3 to 12.2.13 inclusive
  3. Verify the LOV component is accessible
    Test access to the LOV (List of Values) functionality in the CMRO module by attempting to access the typical LOV URL pattern, such as /OA_HTML/olap.jsp or checking web server access logs for requests to LOV-related servlets and JSP pages used by CMRO.
    Affected if The LOV component responds to HTTP requests without requiring authentication
  4. Check network exposure of E-Business Suite web interfaces
    Review firewall rules, load balancer configurations, or Oracle WebGate/OHS configuration to determine if the E-Business Suite login pages and CMRO module are exposed to untrusted networks or the internet.
    Affected if The E-Business Suite web interfaces hosting CMRO are accessible from untrusted networks or the internet without proper access controls

The environment is affected if Oracle E-Business Suite with the Complex Maintenance Repair And Overhaul module version 12.2.3 through 12.2.13 is installed and its web interfaces, particularly the LOV component, are network-accessible.
