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 router model
    Check the device label or access the router's web interface and look for the model number in the status or system information page
    Affected if The device is not a TRENDnet TEW-811DRU router, then this CVE does not apply
  2. Check the firmware version
    Access the router's web interface and navigate to the System or Administration section to view the firmware version, or use the command 'cat /proc/version' via telnet/ssh if available
    Affected if The firmware version is exactly 1.0.10.0, indicating the vulnerable version
  3. Verify the httpd web server is running
    Check if the router's web management interface is accessible by attempting to access the router's IP address on ports 80 or 443
    Affected if The httpd web server is running and responding to HTTP requests
  4. Confirm the /wireless/basic.asp endpoint exists
    Attempt to access the URL path /wireless/basic.asp on the router's web interface (e.g., http://[router-ip]/wireless/basic.asp)
    Affected if The /wireless/basic.asp page is accessible and returns a valid HTTP response
  5. Check network exposure of the management interface
    Determine if the router's web interface is accessible from untrusted networks by reviewing firewall rules or attempting access from an external network
    Affected if The management interface is exposed to untrusted networks, allowing remote attackers to reach the vulnerable endpoint

The environment is affected if you have a TRENDnet TEW-811DRU router running firmware version 1.0.10.0 with the httpd web server and /wireless/basic.asp page accessible, particularly if exposed to untrusted networks.
