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 Enterprise Session Border Controller is installed
    Identify if the Oracle Enterprise Session Border Controller product is running in your environment. Check system documentation, installed software inventory, or consult with system administrators.
    Affected if The product is Oracle Enterprise Session Border Controller
  2. Check installed product version
    Access the system CLI or administrative interface and retrieve the exact version number of the Oracle Enterprise Session Border Controller. Compare against the affected versions 8.4 and 9.0.
    Affected if The installed version is exactly 8.4 or exactly 9.0
  3. Verify WebUI component is enabled
    Check the system configuration to determine if the WebUI component is enabled and accessible. Look for HTTP/HTTPS listener configurations related to the WebUI management interface.
    Affected if WebUI component is enabled and accessible via HTTP
  4. Confirm network accessibility of WebUI
    Determine if the WebUI interface is exposed to network access beyond the intended management network. Check firewall rules, ACLs, and interface bindings for the WebUI port.
    Affected if WebUI is reachable over the network from untrusted or less-privileged network segments

A user is affected if they have Oracle Enterprise Session Border Controller version 8.4 or 9.0 with the WebUI component enabled and network accessible to low-privileged users.
