CVE-2025-29871
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 · uneditedAn out-of-bounds read vulnerability has been reported to affect File Station 5. If a local attacker gains an administrator account, they can then exploit the vulnerability to obtain secret data. We have already fixed the vulnerability in the following version: File Station 5 5.5.6.4847 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 · moderate confidenceThis is an out-of-bounds read vulnerability in File Station 5 that allows a local attacker with administrator privileges to read memory beyond allocated buffers, potentially exposing sensitive data. The vulnerability stems from improper bounds checking when processing certain operations within the file management application.

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 5 is installedAccess the QNAP device's App Center or use the QNAP CLI to list installed applications and confirm File Station 5 is presentAffected if File Station 5 is installed on the device
-
Determine the installed File Station 5 versionOpen App Center, locate File Station 5, and record the version number displayed, or use the QNAP command line interface to query the package versionAffected if The version cannot be determined or File Station 5 is not found
-
Compare version against affected rangeCompare the installed version number to the affected range: versions 5.5.6.4691 through 5.5.6.4846 are vulnerableAffected if The installed version is >= 5.5.6.4691 AND < 5.5.6.4847 (for example, 5.5.6.4700 or 5.5.6.4846)
-
Confirm administrator access contextReview which administrator accounts have access to the device and verify that only trusted users possess administrator privileges, since administrator rights are required for exploitationAffected if Multiple untrusted or unknown accounts have administrator access
A user is affected if File Station 5 is installed with a version between 5.5.6.4691 and 5.5.6.4846 inclusive, and an attacker could obtain administrator credentials.

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 · scoped5.5.6.4847
Update File Station 5 to version 5.5.6.4847 or later. Additionally, enforce strict administrator account controls and monitor for unauthorized privilege escalation since administrator access is required as a prerequisite for exploitation.
File Station 5 version 5.5.6.4847 or later
- 1. Log in to the QNAP NAS as an administrator
- 2. Open the App Center or File Station application
- 3. Check the current version of File Station (should be >= 5.5.6.4691 and < 5.5.6.4847)
- 4. Update File Station to version 5.5.6.4847 or later via the QNAP update mechanism
- 5. Verify the update was successful by checking the File Station version after update
