CVE-2025-58470
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 path traversal vulnerability has been reported to affect Qsync Central. If a remote attacker gains a user account, they can then exploit the vulnerability to read the contents of unexpected files or system data. We have already fixed the vulnerability in the following version: Qsync Central 5.0.0.4 ( 2026/01/20 ) 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 confidenceA path traversal vulnerability in Qsync Central allows an authenticated remote attacker to read arbitrary files on the system by using directory traversal sequences (e.g., ../../../') in file path requests. This enables unauthorized disclosure of configuration files, sensitive system data, or other files accessible to the web server process.

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 Qsync Central installationLocate the Qsync Central application on the QNAP NAS. This is typically accessed via the QNAP admin interface under Application Center or the dedicated Qsync Central portal.Affected if Qsync Central is not installed on the system, the vulnerability does not apply.
-
Determine installed Qsync Central versionAccess the Qsync Central admin interface and navigate to the version information section, typically found in Settings or About. Alternatively, check the QNAP App Center for the installed version of Qsync Central.Affected if The installed version falls within the range >= 5.0.0.0 and < 5.0.0.4, meaning the system is potentially affected by this vulnerability.
-
Verify Qsync Central web service is runningConfirm that the Qsync Central web service is active. This can be done by attempting to access the Qsync Central login page via its web URL (commonly https://[NAS_IP]/qsync or similar) or by checking the service status in the QNAP admin panel.Affected if The Qsync Central web service is not running or accessible, the path traversal attack surface is not present.
-
Check network exposure of Qsync Central interfaceReview the network access settings for Qsync Central in the QNAP admin panel. Determine if the interface is accessible from external networks or only from trusted internal networks.Affected if The Qsync Central interface is exposed to untrusted networks, an authenticated attacker could potentially exploit the path traversal vulnerability.
A system is affected if Qsync Central is installed with a version between 5.0.0.0 and 5.0.0.3 inclusive and the web interface is accessible to potential attackers.

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 · scoped5.0.0.4
Upgrade Qsync Central to version 5.0.0.4 or later. If immediate patching is not possible, limit network exposure of the Qsync Central interface and enforce strong user authentication to reduce the attack surface.
Qsync Central 5.0.0.4
- Access the QNAP NAS admin interface
- Navigate to the Qsync Central application
- Check current Qsync Central version (should be < 5.0.0.4)
- Use the QNAP App Center or Qsync Central update function to install version 5.0.0.4 or later
- Verify the installed version after update
