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. Determine installed ClearPass Policy Manager version via CLI
    Log into the ClearPass CLI and run the command: show version or show inventory
    Affected if The displayed version falls within 6.8.0-6.8.9, 6.9.0-6.9.7, or 6.10.0-6.10.1
  2. Determine installed version via web interface
    Access the ClearPass Policy Manager web UI and navigate to Administration > About or the login page footer to view the version number
    Affected if The version shown is within the affected ranges specified above
  3. Confirm the version number matches affected branches
    Compare your identified version against: 6.8.x branch versions 6.8.0 through 6.8.9; 6.9.x branch versions 6.9.0 through 6.9.7; 6.10.x branch versions 6.10.0 through 6.10.1
    Affected if Your installed version is greater than or equal to 6.8.0 and less than or equal to 6.8.9, OR greater than or equal to 6.9.0 and less than or equal to 6.9.7, OR greater than or equal to 6.10.0 and less than 6.10.2
