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 formVirtualServ.

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 the D-Link DIR600L Ax router firmware (FW116WWb01) within the formVirtualServ function. The curTime parameter accepts user input without proper bounds checking, allowing an attacker to overwrite memory boundaries via specially crafted HTTP requests. This flaw is exploitable over the network without authentication, leading to potential remote code execution.

MitigationApply vendor-provided firmware updates when available. Until then, restrict network access to the device's web management interface using firewall rules or by disabling remote administration.

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 log into the web management interface to confirm the model is D-Link DIR-600L
    Affected if Model is DIR-600L
  2. Check the firmware version
    Log into the router web interface and navigate to the Status or System section to view the firmware version, or use the command 'cat /proc/version' via telnet/SSH if available
    Affected if Firmware version is 1.16wwb01 (FW116WWb01)
  3. Verify web management interface exposure
    Check router firewall settings or attempt to access the router web interface from an external IP address (outside the local network)
    Affected if The web management interface (port 80/443) is accessible from untrusted networks without authentication

You are affected if you have a DIR-600L router running firmware 1.16wwb01 and its web interface is accessible over the network without authentication.
