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 Business Process Management Suite product of Oracle Fusion Middleware (component: Human workflow 11g+). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Business Process Management Suite. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Business Process Management Suite, 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 Business Process Management Suite accessible data as well as unauthorized read access to a subset of Oracle Business Process Management Suite 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 · moderate confidence

Unauthenticated HTTP vulnerability in Oracle BPM Suite's Human Workflow component (versions 12.2.1.4.0 and 14.1.2.0.0) allows remote attackers to achieve unauthorized read access and partial write/delete access to data. The required human interaction (UI:R) combined with scope change (S:C) suggests a client-side injection flaw likely enabling indirect attacks against other products.

MitigationApply Oracle Critical Patch Updates for Oracle Business Process Management Suite; until patches are available, restrict network access to BPM interfaces and monitor for anomalous HTTP 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. Identify Oracle BPM Suite installation
    Locate Oracle BPM Suite installation directory. Common paths include $ORACLE_HOME/bpm on Oracle WebLogic servers. Check for presence of 'Oracle_BPM' or 'bpm' directories in the Oracle middleware home.
    Affected if Oracle BPM Suite is installed on the system
  2. Determine installed BPM Suite version
    Check the version file or manifest in the BPM installation directory. Run: grep -r '12.2.1.4.0\|14.1.2.0.0' $ORACLE_HOME/bpm or examine the OPatch inventory: $ORACLE_HOME/OPatch/opatch lsinventory -detail | grep -i bpm
    Affected if Installed version matches exactly 12.2.1.4.0 or 14.1.2.0.0
  3. Verify Human Workflow component is deployed
    Check WebLogic Administration Console for deployed 'Human Workflow' or 'bpm-workflow' ear/lib deployments. Alternatively, inspect: ls $ORACLE_HOME/bpm/modules/oracle.bpm.workflow* 2>/dev/null
    Affected if Human Workflow component is deployed and enabled on the WebLogic server
  4. Confirm HTTP access to BPM interfaces
    Test HTTP/HTTPS accessibility of common BPM endpoints: curl -I http://<host>:<port>/bpm/services or http://<host>:<port>/bpm/workspace. Check WebLogic HTTP channel configuration for BPM-managed servers.
    Affected if BPM HTTP endpoints are externally accessible without authentication required
  5. Check for unauthenticated HTTP endpoint exposure
    Send unauthenticated HTTP requests to Human Workflow endpoints such as: curl -s http://<host>:<port>/bpm/services/HumanTaskService?wsdl or curl -s http://<host>:<port>/bpm/workspace/. Verify if responses return without 401/403 authentication errors.
    Affected if Human Workflow HTTP endpoints respond to unauthenticated requests with valid SOAP/XML content

User is affected if Oracle BPM Suite versions 12.2.1.4.0 or 14.1.2.0.0 are installed with the Human Workflow component exposed via HTTP and accessible without authentication.
