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 File Station 5 is installed
    Access QNAP App Center or use the command line to list installed applications and verify File Station 5 is present on the system
    Affected if File Station 5 is not installed, this CVE does not apply
  2. Identify the installed File Station 5 version
    In QNAP File Station, go to Settings > About, or use the QNAP CLI command 'qpkg info FileStation5' to retrieve the exact version number
    Affected if Unable to determine version - cannot assess vulnerability status
  3. Compare version against affected range
    Check if the installed version falls within >= 5.5.6.4691 and < 5.5.6.4791. Versions 5.5.6.4691 through 5.5.6.4790 are affected
    Affected if Version is 5.5.6.4691 through 5.5.6.4790 inclusive - system is vulnerable to improper certificate validation
  4. Assess exposure to network attacks
    Review whether File Station is configured to connect to remote servers via HTTPS (such as remote mounts, cloud links, or external storage connections). This vulnerability is exploitable when these connections are made over untrusted networks
    Affected if File Station makes HTTPS connections to remote servers and the version is within the affected range, the improper certificate validation could allow MITM attacks

System is affected if File Station 5 version is between 5.5.6.4691 and 5.5.6.4790 inclusive and the application is used to establish HTTPS connections to remote servers.
