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
D-Link DIR600L Ax FW116WWb01 was discovered to contain a buffer overflow via the curTime parameter in the function formSetWAN_Wizard7.

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

A buffer overflow vulnerability exists in D-Link DIR600L Ax router firmware FW116WWb01 within the formSetWAN_Wizard7 function. The curTime parameter is not properly validated, allowing an attacker to send overly long input and overflow a buffer, potentially enabling remote code execution or denial of service.

MitigationApply available firmware updates from D-Link; if unavailable, restrict access to the router's web management interface to trusted internal networks only or disable remote management.

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. Confirm device model is D-Link DIR600L
    Access the router's web interface and check the status page, or use Nmap to identify the device via its HTTP response headers or HTML title
    Affected if Device is a D-Link DIR600L variant (Ax or Bx)
  2. Check firmware version matches 1.16wwb01
    Log into the router web interface, navigate to Status or System > Firmware, and compare the displayed version against '1.16wwb01'
    Affected if Firmware version is exactly 1.16wwb01 (no patches applied)
  3. Verify web management interface is accessible
    Attempt to reach the router's HTTP (port 80) or HTTPS (port 443) interface from the network position you are testing
    Affected if Web interface responds with D-Link login page or returns HTTP 200 on the WAN interface
  4. Check if remote management is enabled
    In the router web interface, go to Advanced > Remote Management, or inspect firewall rules that may permit inbound HTTP/HTTPS to the LAN IP from WAN
    Affected if Remote management is enabled or firewall permits external access to port 80/443

User is affected if the device is a D-Link DIR600L running firmware 1.16wwb01 and its web management interface (with the vulnerable formSetWAN_Wizard7 function) is reachable, either locally or remotely.
