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
An out-of-bounds read vulnerability has been reported to affect Media Streaming add-on. If an attacker gains local network access, they can then exploit the vulnerability to obtain secret data. We have already fixed the vulnerability in the following version: Media Streaming add-on 500.1.1.6 ( 2024/08/02 ) 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

An out-of-bounds read vulnerability in the Media Streaming add-on allows a local network attacker to read memory beyond allocated buffers, potentially exposing secret data. The vulnerability is triggered through the media streaming functionality and requires network proximity for exploitation.

MitigationUpgrade Media Streaming add-on to version 500.1.1.6 or later. As a defense-in-depth measure, restrict network access to the media streaming service and implement network segmentation to limit exposure to local network attackers.

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. Verify Media Streaming add-on is installed
    Access QTS and navigate to App Center, or use QNAP CLI to list installed applications. Look for 'Media Streaming Add-On' or similar media streaming package.
    Affected if The Media Streaming add-on appears in the installed applications list
  2. Determine Media Streaming add-on version
    In QTS App Center, click on the Media Streaming add-on and view its version information. Alternatively, use the command line to query the installed package version.
    Affected if The displayed version falls within 500.1.1.0 through 500.1.1.5 (anything less than 500.1.1.6)
  3. Confirm media streaming service is enabled
    Check the Media Streaming add-on settings in QTS. Look for the streaming service status or enable/disable toggle within the add-on configuration.
    Affected if The media streaming service is currently enabled and accessible on the network
  4. Verify network exposure of the media streaming port
    Check your QNAP firewall settings and port forwarding rules. Identify which network ports the media streaming service is bound to and whether they are accessible from the local network.
    Affected if The media streaming service port is open to the local network without restriction

A user is affected if the Media Streaming add-on version is 500.1.1.0 through 500.1.1.5, the add-on is installed, and the media streaming functionality is enabled and accessible on the network.

Upgrade available Upgrade to 500.1.1.6 or later
Fixed in 500.1.1.6
Interim mitigation

Upgrade Media Streaming add-on to version 500.1.1.6 or later. As a defense-in-depth measure, restrict network access to the media streaming service and implement network segmentation to limit exposure to local network attackers.

Recommended fix High confidence

Media Streaming add-on 500.1.1.6

  1. Access the QNAP NAS admin interface (QTS or QuTS hero)
  2. Navigate to App Center or the specific add-on management section
  3. Locate the Media Streaming add-on in the installed applications
  4. Check the current version to confirm it is between 500.1.1.0 and 500.1.1.5 (exclusive)
  5. Look for and install the available update for Media Streaming add-on
  6. Verify that version 500.1.1.6 or later has been installed after the update completes
