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
TP-Link WR740N V6 has a stack overflow vulnerability via the ssid parameter in /userRpm/popupSiteSurveyRpm.htm url.

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

Stack overflow vulnerability in TP-Link WR740N V6 router's web interface allows remote attackers to overflow the stack via the ssid parameter in the /userRpm/popupSiteSurveyRpm.htm URL endpoint.

MitigationApply vendor firmware update if available; otherwise isolate device on network segment or replace with supported hardware.

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 TP-Link WR740N device on your network
    Check your DHCP lease table, network scan results, or physical device label to confirm the device model number is TP-Link WR740N (particularly V6 variant)
    Affected if Device is a TP-Link WR740N router
  2. Check if web interface is accessible
    Attempt to access the router's web interface by entering the device's IP address in a web browser (commonly 192.168.0.1 or 192.168.1.1)
    Affected if Web interface responds and shows TP-Link login page
  3. Verify the vulnerable endpoint exists
    Navigate to the path /userRpm/popupSiteSurveyRpm.htm on the router's web interface (may require authentication)
    Affected if Endpoint returns a response rather than a 404 error
  4. Confirm firmware version
    Login to the router web interface and navigate to System Tools > Firmware Upgrade or Status page to view the installed firmware version
    Affected if Any firmware version is installed on the WR740N (all versions affected)
  5. Check if web interface is exposed to network
    Determine if the router's HTTP/HTTPS ports (80/443) are accessible from untrusted network segments or the internet using a port scanner or firewall rules review
    Affected if Web interface is reachable from outside the trusted local network

If you have a TP-Link WR740N router with an accessible web interface and the /userRpm/popupSiteSurveyRpm.htm endpoint exists, your environment is affected by this vulnerability.
