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 Advanced Inbound Telephony installation
    Query your Oracle E-Business Suite applications for the presence of the Advanced Inbound Telephony module. This may be listed in the installed modules, about page, or application inventory.
    Affected if Oracle Advanced Inbound Telephony is installed and part of the E-Business Suite deployment
  2. Check installed version number
    Locate the version information for Oracle Advanced Inbound Telephony. This is typically found in the application about pages, version information screens, or via Oracle application diagnostic queries. Compare your version against the affected range 12.2.3 through 12.2.15.
    Affected if The installed version falls within 12.2.3 to 12.2.15 inclusive
  3. Verify Setup and Administration component is configured
    Check whether the Setup and Administration component of Oracle Advanced Inbound Telephony is enabled and accessible within the application. This may be visible in the module navigation or component list.
    Affected if The Setup and Administration component is present and accessible in the deployment
  4. Assess network accessibility via HTTP
    Determine if the Oracle E-Business Suite web interfaces, including the Advanced Inbound Telephony component, are exposed to untrusted networks via HTTP/HTTPS. Review load balancer, web server, and firewall configurations for external access rules.
    Affected if The application is reachable over HTTP from untrusted or external networks

You are affected if Oracle Advanced Inbound Telephony version 12.2.3 through 12.2.15 is installed with the Setup and Administration component accessible over HTTP to untrusted networks.
