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 Workflow product of Oracle E-Business Suite (component: Workflow Loader). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows high privileged attacker with network access via HTTP to compromise Oracle Workflow. While the vulnerability is in Oracle Workflow, 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 Workflow accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Workflow. CVSS 3.1 Base Score 5.5 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:L/A:L).

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

Vulnerability in Oracle Workflow's Workflow Loader component allows high-privileged authenticated attackers via HTTP to perform unauthorized update, insert, or delete operations on some Oracle Workflow data, plus cause partial denial of service. The CVSS vector indicates low integrity and availability impact (I:L/A:L) with changed scope affecting additional products.

MitigationApply Oracle Critical Patch Update for this vulnerability to Oracle E-Business Suite 12.2.3-12.2.15. Until patch is available, restrict network access to Workflow Loader and monitor for unauthorized data manipulation or anomalous API 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. Verify Oracle Workflow is installed
    Check if Oracle E-Business Suite with Oracle Workflow component is deployed. Look for $FND_TOP or $WF_TOP environment variables set, or check for Oracle Workflow tables in the database (e.g., WF_TABLES exists).
    Affected if Oracle Workflow is not present in the environment.
  2. Determine installed Oracle Workflow version
    Query the Oracle database: SELECT ad品.获取版本 FROM applsys.fnd_product_groups pg; OR check the ORA$APPL_TOP version files. Compare the version against the affected range: 12.2.3 through 12.2.15.
    Affected if Version is >= 12.2.3 and <= 12.2.15.
  3. Confirm Workflow Loader component is configured
    Check if the Workflow Loader (FWKLDMR) concurrent program is registered and enabled. Query: SELECT concurrent_program_name FROM fnd_concurrent_programs WHERE concurrent_program_name LIKE '%FWKLDMR%'; OR check the Oracle Applications Manager interface.
    Affected if Workflow Loader is not registered or is disabled.
  4. Verify HTTP access to Workflow Loader
    Review Oracle E-Business Suite web tier configuration for /OA_HTML/wf/ endpoints or the Workflow Loader servlet access. Check OHS/webcache configuration files and Oracle E-Business Suite web listener settings.
    Affected if Workflow Loader is accessible via HTTP without authentication.
  5. Audit recent Workflow Loader activity
    Review concurrent request logs and WF_LOGS table for recent Workflow Loader executions. Check fnd_concurrent_requests for unexpected or unauthorized job submissions with program 'FWKLDMR' or related load operations.
    Affected if Unauthorized or unexpected Workflow Loader executions are found.

Environment is affected if Oracle Workflow version is between 12.2.3 and 12.2.15 inclusive AND the Workflow Loader component is enabled and accessible.
