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
    Check for Oracle E-Business Suite by reviewing environment variables (ORACLE_HOME, $APPS_CONTEXT), or look for Oracle-specific directory structures such as $APPL_TOP, $ORACLE_HOME, or the presence of Oracle E-Business Suite configuration files in the system.
    Affected if Oracle E-Business Suite is present on the server.
  2. Determine the exact EBS version
    Query the Oracle Applications version using SQL*Plus connected as APPS user: SELECT release_name FROM fnd_product_groups; or check the context file (typically located in $APPL_TOP/admin/<context_name>.xml) for the release version.
    Affected if The version falls within 12.2.3 through 12.2.12 inclusive.
  3. Verify the DBA Java utils component is accessible
    Check if the DBA Java utils are exposed via HTTP/HTTPS by attempting to access the URL path /oa_servlets/oracle.apps.fnd.diagnostics.Diag or reviewing web tier configuration files (like mod_plsql configuration) for servlet mappings related to DBA utilities.
    Affected if The DBA Java utils servlet is mapped and accessible through the web listener.
  4. Confirm HTTP/HTTPS listener exposure
    Review the web tier configuration (HTTP Server httpd.conf, Oracle Web Listener settings) or test network connectivity to the Oracle E-Business Suite ports (typically 8000, 8080, or 443) from untrusted networks to determine if the application is externally accessible.
    Affected if The Oracle E-Business Suite HTTP/HTTPS ports are reachable from untrusted or public networks without proper network filtering.

A user is affected if Oracle E-Business Suite version 12.2.3-12.2.12 is installed, the DBA Java utils component is exposed via HTTP/HTTPS, and the interface is accessible from untrusted networks.

Upgrade available Upgrade to a release after 12.2.12
Interim mitigation

Apply Oracle Critical Patch Update (CPU) for January 2023 or subsequent relevant security patches. Restrict HTTP/HTTPS access to Oracle Applications DBA interfaces to trusted networks if immediate patching is not feasible.

Recommended fix Moderate confidence

Upgrade to a version beyond 12.2.12 (e.g., 12.2.13 or latest 12.2.x stable release) that includes the CVE-2023-21849 fix

  1. 1. Review Oracle Critical Patch Update advisories for CVE-2023-21849 on oracle.com for the specific patch bundle applicable to your Oracle E-Business Suite version.
  2. 2. Identify your current Oracle Applications DBA Java utils component version via Oracle E-Business Suite administration utilities.
  3. 3. Apply the relevant Oracle Critical Patch Update that addresses CVE-2023-21849, following Oracle's standard patching procedures for E-Business Suite.
  4. 4. After patching, verify the Oracle Applications DBA component has been updated and test functionality to ensure the fix was applied correctly.
Caveat Oracle E-Business Suite upgrades may require regression testing of custom integrations; review Oracle's upgrade documentation for 12.2.x series
