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 versionAccess the QNAP admin console, navigate to Control Panel > Applications > Qsync Central, or check the installed packages list. The version number is displayed in the application details or package manager.Affected if The displayed version is 4.5.0.3, 4.5.0.4, or 4.5.0.5 (any version >= 4.5.0.3 but < 4.5.0.6)
-
Confirm Qsync Central is runningVerify the Qsync Central service is active by checking the QNAP services status page or using the command line: qpkg | grep -i qsyncAffected if Qsync Central service is running on a vulnerable version
-
Assess user access exposureReview user accounts configured in Qsync Central and check if the application is accessible to users beyond trusted internal personnel. Check Network Access settings in QNAP to determine if Qsync is exposed beyond the local network.Affected if Untrusted or external users have Qsync Central access, or the service is exposed to untrusted networks
-
Inspect logs for suspicious SQL activityExamine Qsync Central logs in the QNAP log center or the Qsync logs directory (/share/Qsync/logs/) for entries containing unusual SQL syntax, unexpected WHERE clauses, or SQL error messages that may indicate exploitation attempts.Affected if Logs contain SQL-like errors, unusual query patterns, or evidence of SQL injection probing
You are affected if Qsync Central version is 4.5.0.3, 4.5.0.4, or 4.5.0.5 AND untrusted users can access the Qsync service.
