CVE-2025-29894
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 4.5.0.7 ( 2025/04/23 ) 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 confidenceSQL injection vulnerability in Qsync Central allowing authenticated users to execute unauthorized code or commands via malicious SQL queries. The CVSS 8.8 indicates network-exploitable attack vector with low complexity but requires an attacker to first obtain a valid user account before exploitation.

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.
-
Locate Qsync Central installationAccess the QNAP admin interface (QTS/QuTScloud) or locate the Qsync Central server. Identify the host running the Qsync Central application.Affected if Qsync Central is deployed on the system
-
Identify installed Qsync Central versionLog into Qsync Central admin console, navigate to Settings or About section, and record the exact version number displayed (e.g., 4.5.0.3, 4.5.0.5, 4.5.0.6).Affected if Version is 4.5.0.3, 4.5.0.4, 4.5.0.5, or 4.5.0.6 (any version >=4.5.0.3 but <4.5.0.7)
-
Verify SQL query interface is accessibleConfirm that Qsync Central web interface is reachable and the login page is accessible. Note that exploitation requires a valid user account with authentication privileges.Affected if Qsync Central web interface is exposed and accepts user authentication
A system is affected if Qsync Central version is 4.5.0.3, 4.5.0.4, 4.5.0.5, or 4.5.0.6 (any version from 4.5.0.3 through 4.5.0.6) and the web interface is accessible for authenticated exploitation.

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 · scoped4.5.0.7
Update Qsync Central to version 4.5.0.7 or later. Additionally, review user account security, enforce strong password policies, implement account monitoring, and audit existing accounts for compromise since the vulnerability requires an authenticated session.
Qsync Central 4.5.0.7
- Identify the current version of Qsync Central installed on the system
- If the current version is less than 4.5.0.7 (i.e., any version >= 4.5.0.3 but < 4.5.0.7), download and install Qsync Central version 4.5.0.7 or later from the official QNAP website
- After upgrading, verify the installed version is 4.5.0.7 or higher to confirm the vulnerability is patched
