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
Mediabridge Medialink MWN-WAPR300N devices with firmware 5.07.50 and Tenda N3 Wireless N150 devices allow remote attackers to obtain administrative access via a certain admin substring in an HTTP Cookie header.

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 confidence

Authentication bypass vulnerability in Mediabridge Medialink MWN-WAPR300N (firmware 5.07.50) and Tenda N3 Wireless N150 routers allows remote attackers to gain administrative privileges by including an 'admin' substring in the HTTP Cookie header, bypassing normal authentication controls.

MitigationUpdate router firmware if a patch is available; otherwise replace affected devices with currently supported models, as these legacy consumer routers are likely end-of-life with no security updates.

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 router model
    Locate the router label on the device or log into the admin web interface (typically at 192.168.0.1 or 192.168.1.1) and check the device model under Status or System Information pages
    Affected if Model is Mediabridge Medialink MWN-WAPR300N or Tenda N3 Wireless N150
  2. Check firmware version
    In the router admin web interface, navigate to Status or System Information to view the installed firmware version
    Affected if Firmware version is 5.07.50 or lower on Mediabridge Medialink MWN-WAPR300N, or any version on Tenda N3 Wireless N150
  3. Test authentication bypass vulnerability
    Send an HTTP request to the router login page with a Cookie header containing the substring 'admin' (for example: Cookie: admin=1 or Cookie: username=admin). Observe if the request is granted administrative access without valid credentials
    Affected if The router grants administrative access when the Cookie header contains 'admin' substring, bypassing normal authentication

Your environment is affected if you operate a Mediabridge Medialink MWN-WAPR300N router with firmware 5.07.50 or lower, or any Tenda N3 Wireless N150 router, and the cookie-based authentication bypass test succeeds.

dbcve · scoped
Upgrade available Upgrade to a release after 5.07.50
Interim mitigation

Update router firmware if a patch is available; otherwise replace affected devices with currently supported models, as these legacy consumer routers are likely end-of-life with no security updates.

Recommended fix Moderate confidence

Latest firmware version available from Medialink or Tenda support website (specific version numbers not disclosed in vulnerability note)

  1. 1. Identify the exact model number of the affected device (Medialink MWN-WAPR300N or Tenda N3 Wireless N150)
  2. 2. Visit the manufacturer's official support website to check for available firmware updates
  3. 3. Download the latest firmware version available for your specific model
  4. 4. Consult the device's user manual for firmware update instructions, typically involving accessing the web administration interface
  5. 5. Backup current device configuration before applying the firmware update
  6. 6. Apply the firmware update following manufacturer instructions
  7. 7. After updating, verify the vulnerability is resolved by attempting the Cookie-based authentication bypass
  8. 8. If no firmware update is available from the manufacturer, consider replacing the device with a newer model that receives active security support
Caveat Firmware updates on legacy router devices may reset configuration to factory defaults; backup configuration before updating
