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 Cisco Unity Connection installation
    Locate the Cisco Unity Connection application on the system or check the installed packages/services associated with Cisco unified communications products.
    Affected if The system has Cisco Unity Connection deployed as the unified communications messaging platform.
  2. Verify exact version number
    Access the Unity Connection administrative interface or check the installed software version through the system's software inventory. The affected version is specifically 10.5(2.3009).
