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.
-
Verify File Station is installedAccess QNAP QTS admin interface and navigate to App Center or check if File Station appears in the application listAffected if File Station is not installed or not in use, the vulnerability does not apply
-
Locate the File Station versionIn QTS, open File Station and click the menu icon, then select 'About' or 'Help' > 'About' to display the version numberAffected if Cannot determine version, further investigation needed through QNAP control panel or CLI
-
Compare version against affected rangeNote the full version number (format: x.x.x.xxxx) and compare: affected if version is 5.5.6.4691 through 5.5.6.4790 inclusiveAffected if Installed version is greater than or equal to 5.5.6.4691 AND less than 5.5.6.4791
-
Confirm vulnerability scopeNote that this flaw requires an attacker to already have user-level access to the File Station applicationAffected if The system is only vulnerable if an attacker can interact with File Station with user credentials
The environment is affected if QNAP File Station version is 5.5.6.4691 through 5.5.6.4790, and an attacker with user-level access to File Station could exploit improper certificate validation.

dbcve · scoped5.5.6.4791
Update File Station to version 5.5.6.4791 or later to apply the vendor fix for proper certificate validation.
File Station 5.5.6.4791 or later
- Log in to the QNAP NAS administration interface
- Navigate to File Station
- Check the current version under the application settings or about section
- If the installed version is between 5.5.6.4691 and 5.5.6.4791 (exclusive), proceed with update
- Update File Station to version 5.5.6.4791 or later through the QNAP App Center or firmware update mechanism
- Verify the update was successful by checking the installed version after upgrade
