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 formSetEnableWizard.

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 formSetEnableWizard function. The vulnerability is triggered via the curTime parameter, allowing remote attackers to potentially execute arbitrary code or cause denial of service.

MitigationIf a firmware update is available from D-Link, apply it immediately. Otherwise, disable remote management interfaces, restrict access to trusted IPs only, or consider replacing the end-of-life device.

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
    Log into the router web interface or check the physical device label for the exact model number D-Link DIR-600L
    Affected if Device is not a DIR-600L model
  2. Check firmware version
    Access router web UI (usually at 192.168.0.1) and navigate to Status or Management section to view the firmware version, or check via CLI if telnet/ssh is enabled
    Affected if Firmware version is 1.16wwb01 (FW116WWb01)
  3. Verify remote management status
    In router web UI, go to Advanced > Remote Management (or similar section) and check if Enable Remote Management is checked or if a remote access port is open
    Affected if Remote management is enabled and accessible from WAN
  4. Check WAN exposure
    Attempt to access the router login page from an external IP (or use an online port scanner on your public IP) to confirm if HTTP/HTTPS ports are listening on WAN interface
    Affected if Router management interface is exposed directly to the internet on WAN

Device is affected if it is a D-Link DIR-600L running firmware version 1.16wwb01 and remote management is enabled or the device is accessible from the internet.
