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_Wizard52.

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 firmware FW116WWb01. The vulnerability is triggered through the curTime parameter in the formSetWAN_Wizard52 function, allowing an attacker to overwrite memory due to insufficient bounds checking. The critical CVSS score of 9.8 indicates potential for complete compromise of the device.

MitigationApply vendor-supplied firmware patches when available. Until a patch is released, restrict network access to the device's management interface and disable remote administration to reduce attack surface.

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 device model
    Access the device's web administration interface or check the device label. Look for the model number DIR-600L in the web interface under Status, System, or Device Info pages.
    Affected if The device is not a D-Link DIR-600L, the check does not apply.
  2. Check firmware version
    In the web interface, navigate to Status or System section and locate the firmware version field. The affected version is specifically FW116WWb01 or 1.16wwb01.
    Affected if The installed firmware version is exactly 1.16wwb01 (FW116WWb01).
  3. Verify web interface is accessible
    Attempt to access the device's management interface via HTTP/HTTPS on the LAN IP address (typically 192.168.0.1). Confirm the login page loads.
    Affected if The web interface is reachable - this is required for exploitation.
  4. Check remote administration status
    In the web interface, go to Tools > Admin or Advanced > Remote Management settings. Look for options labeled 'Remote Management', 'Remote Access', or 'Enable Web Server' that allow access from WAN.
    Affected if Remote administration is enabled and the management interface is exposed to WAN, the device is at higher risk of remote attack.

The device is affected if it is a D-Link DIR-600L running firmware version 1.16wwb01 (FW116WWb01) and the formSetWAN_Wizard52 function with the curTime parameter is accessible.

Mitigation

Apply vendor-supplied firmware patches when available. Until a patch is released, restrict network access to the device's management interface and disable remote administration to reduce attack surface.
