CVE-2025-29888
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA NULL pointer dereference vulnerability has been reported to affect File Station 5. If a remote attacker gains a user account, they can then exploit the vulnerability to launch a denial-of-service (DoS) attack. We have already fixed the vulnerability in the following version: File Station 5 5.5.6.4907 and later
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA NULL pointer dereference vulnerability in File Station 5 allows an authenticated remote attacker to cause a denial-of-service condition. The vulnerability can be triggered after the attacker obtains a valid user account on the affected system, leading to application crash or unavailability.

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.
-
Confirm File Station 5 is installedAccess QNAP QTS via web interface, go to App Center and look for File Station in the installed applications list, or run 'qpkg info File Station 5' via SSH if availableAffected if File Station 5 is not listed as installed, the system is not affected by this vulnerability
-
Identify installed File Station versionIn QTS web interface, go to App Center > File Station > Settings > About, or check the version via QNAP CLI with command 'appcenter get package version File Station 5'Affected if The installed version is >= 5.5.6.4691 and < 5.5.6.4907, meaning the system falls within the affected version range
-
Verify remote access is enabledIn QTS, go to Control Panel > Network & File Services > Web Server and confirm File Station remote access/web interface is accessible from networkAffected if Remote access to File Station web interface is enabled and exposed to network, allowing authenticated remote attackers to reach the vulnerable component
-
Check for existing user accountsIn QTS, go to Control Panel > User Management > Users to view all local user accounts on the systemAffected if There are one or more user accounts present (other than admin), as an attacker needs a valid user account to trigger the NULL pointer dereference
The system is affected if File Station 5 is installed with version 5.5.6.4691 through 5.5.6.4906, remote access is enabled, and at least one user account exists that could be obtained by an attacker.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped5.5.6.4907
Update File Station to version 5.5.6.4907 or later. Limit the creation of user accounts and monitor for unusual DoS symptoms as a secondary defensive measure.
File Station 5.5.6.4907 or later
- Log in to the QNAP NAS admin interface
- Navigate to App Center or the File Station application management section
- Check for available updates for File Station
- Update File Station to version 5.5.6.4907 or later
- Verify the installed version after update completes
