CVE-2025-54153
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 SQL injection vulnerability has been reported to affect Qsync Central. If a remote attacker gains a user account, they can then exploit the vulnerability to execute unauthorized code or commands. We have already fixed the vulnerability in the following version: Qsync Central 5.0.0.2 ( 2025/07/31 ) 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.

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.
-
Check Qsync Central installed versionAccess the QNAP NAS via SSH and run: `qpkg --info Qsync` or check the version via QTS web interface under App Center > Qsync Central > InfoAffected if The displayed version is 5.0.0.0 or 5.0.0.1 (versions 5.0.0.0 through 5.0.0.1 are vulnerable)
-
Verify Qsync Central application is runningVia QTS web interface, navigate to Control Panel > Application Service > Qsync Central or check via SSH with: `ps | grep -i qsync`Affected if Qsync Central service is active and running on the system
-
Confirm user authentication is enabledCheck that local or domain user accounts exist on the QNAP NAS via Control Panel > User and Group or command: `getent passwd`Affected if Any valid user accounts are present on the system, as the SQL injection requires authentication to exploit
-
Identify Qsync Central database configurationExamine the Qsync Central configuration files in /share/Qsync/ or via QTS web interface under Qsync Central settingsAffected if The application uses a database that accepts SQL queries, which is the default configuration
If Qsync Central version is 5.0.0.0 or 5.0.0.1 and the service is running with authenticated user accounts present, the system is vulnerable to SQL injection attacks.
Generated from the published advisory. Verify against your own configuration.
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 · scoped5.0.0.2
Update Qsync Central to version 5.0.0.2 or later. Additionally, enforce strong user account security to prevent attackers from gaining the initial authentication required to exploit this vulnerability.
Qsync Central 5.0.0.2
- Identify the current version of Qsync Central installed on the system
- Verify the current version is >= 5.0.0.0 and < 5.0.0.2 (affected version range)
- Download Qsync Central version 5.0.0.2 or later from the official QNAP website
- Follow QNAP's standard upgrade procedure for Qsync Central to install version 5.0.0.2
- Verify the upgraded version is 5.0.0.2 or later and the application is functioning normally
