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 checksWork through these to decide whether this CVE applies to you.
-
Identify File Station versionAccess the QNAP admin console, navigate to the App Center or File Station settings, and locate the installed version number of File Station 5Affected if The installed version is 5.5.6.4691 or higher but lower than 5.5.6.5018
-
Confirm vulnerable version rangeCompare your installed File Station version against the affected range: versions >= 5.5.6.4691 and < 5.5.6.5018 are vulnerableAffected if Your version falls within 5.5.6.4691 through 5.5.6.5017 inclusive
-
Verify File Station is accessibleConfirm that the File Station web interface is enabled and accessible on your QNAP NASAffected if File Station is enabled and reachable, providing an attack surface for authenticated XSS exploits
You are affected if File Station 5 is installed with a version between 5.5.6.4691 and 5.5.6.5017 inclusive and the application is accessible to authenticated users.
