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 if Cisco WebEx ARF player is installed
    On Windows, open Control Panel > Programs and Features, or run 'appwiz.cpl', and look for entries containing 'WebEx' or 'Advanced Recording Format Player'. On macOS, check /Applications for WebEx folder or use Spotlight to search for 'WebEx' or 'ARF Player'.
    Affected if No WebEx ARF player software is found on the system.
  2. Determine the installed version number
    In Windows Programs and Features, select the WebEx ARF player entry and note the version shown in the details pane, or right-click and select Properties > Details to view the Version field. On macOS, right-click the WebEx application in Applications, select Get Info, and note the Version field.
    Affected if The version cannot be determined or the software is not listed.
  3. Compare installed version against affected ranges
    Check if the installed version falls within any of these ranges: 27.11.0 through 27.11.26, 27.21.0 through 27.21.10, 27.25.0 through 27.25.10, 27.32.0 through 27.32.1, or 28.0.0.
    Affected if The installed version matches any of the affected version ranges listed.
  4. Verify ARF file handling capability exists
    Check if .arf file association exists on the system. On Windows, search for files with .arf extension or check the default file associations in Settings > Apps > Default Apps > Choose default apps by file type. Also look for WebEx recording-related files in common document directories.
    Affected if ARF file associations are present and the player can process these files.

A user is affected if the Cisco WebEx ARF player is installed with a version matching any of the specified vulnerable ranges and the system can open or process ARF files.
