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 · unedited
A vulnerability involving insecure storage of sensitive information has been reported to affect QSW-M2116P-2T2S and QNAP switches running QuNetSwitch. If exploited, this vulnerability allows remote attackers to read sensitive information by accessing the unrestricted storage mechanism.We have already fixed this vulnerability in the following versions: QSW-M2116P-2T2S 1.0.6 build 210713 and later QGD-1600P: QuNetSwitch 1.0.6.1509 and later QGD-1602P: QuNetSwitch 1.0.6.1509 and later QGD-3014PT: QuNetSwitch 1.0.6.1519 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 confidence

QNAP switches (QSW-M2116P-2T2S and models running QuNetSwitch) contain an insecure storage vulnerability allowing remote attackers to read sensitive information through an unrestricted storage mechanism. This high-severity (CVSS 7.5) information disclosure vulnerability stems from improper access controls on stored data.

MitigationUpdate affected devices to the patched firmware versions: QSW-M2116P-2T2S to version 1.0.6 build 210713 or later, and QuNetSwitch to version 1.0.6.1509/1519 or later depending on the specific model (QGD-1600P, QGD-1602P, or QGD-3014PT).

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Access the QNAP switch admin interface or check the device label to confirm the exact model number (QSW-M2116P-2T2S or a QuNetSwitch model such as QGD-1600P, QGD-1602P, or QGD-3014PT)
    Affected if The device is a QSW-M2116P-2T2S or any QuNetSwitch model
  2. Check the firmware version for QSW-M2116P-2T2S
    In the switch admin panel, navigate to System > Firmware or use the 'get system info' command via CLI to retrieve the current firmware build number
    Affected if The firmware version is earlier than 1.0.6 (or specifically earlier than build 210713)
  3. Check the firmware version for QuNetSwitch models
    In the switch admin panel, navigate to System > Firmware or use the 'get system info' command via CLI to retrieve the current firmware version
    Affected if The firmware version is earlier than 1.0.6.1509 (or 1.0.6.1519 depending on the specific QuNetSwitch model)
  4. Verify storage access controls
    Attempt to access the storage management interface or API endpoints on the device to determine if sensitive data storage locations are accessible without authentication or with insufficient authorization
    Affected if Storage interfaces or data files are accessible without proper authentication or expose sensitive information to unauthenticated users

A user is affected if they own a QSW-M2116P-2T2S or QuNetSwitch model running firmware versions below 1.0.6 (or below 1.0.6.1509/1519 for QuNetSwitch) with exposed storage mechanisms

Upgrade available Upgrade to 1.0.6 / 1.0.6.1509 or later
Fixed in 1.0.61.0.6.1509
Interim mitigation

Update affected devices to the patched firmware versions: QSW-M2116P-2T2S to version 1.0.6 build 210713 or later, and QuNetSwitch to version 1.0.6.1509/1519 or later depending on the specific model (QGD-1600P, QGD-1602P, or QGD-3014PT).

Recommended fix High confidence

QSW-M2116P-2T2S: 1.0.6 (build 210713) | QGD-1600P/QGD-1602P: QuNetSwitch 1.0.6.1509 | QGD-3014PT: QuNetSwitch 1.0.6.1519

  1. 1. Identify the exact QNAP switch model (QSW-M2116P-2T2S, QGD-1600P, QGD-1602P, or QGD-3014PT)
  2. 2. Check the current firmware version via the switch management interface
  3. 3. Navigate to the official QNAP support website (www.qnap.com) and locate the firmware download section for your specific model
  4. 4. Download the appropriate fixed firmware: For QSW-M2116P-2T2S, download version 1.0.6 build 210713 or later; For QGD-1600P/QGD-1602P, download QuNetSwitch version 1.0.6.1509 or later; For QGD-3014PT, download QuNetSwitch version 1.0.6.1519 or later
  5. 5. Access the switch administration panel and navigate to the firmware update section
  6. 6. Upload the downloaded firmware file and initiate the update process
  7. 7. Wait for the update to complete and verify the new firmware version is installed
Caveat Firmware updates may cause temporary service interruption; ensure proper backup of configuration before proceeding
