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 next_page parameter in the function formDeviceReboot.

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 firmware (FW116WWb01) within the formDeviceReboot function. The next_page parameter is not properly validated, allowing an attacker to overflow a buffer by providing excessively long input. This memory corruption could potentially allow remote code execution or cause device denial of service.

MitigationSince D-Link DIR600L is an End-of-Life product with no official security updates, replace the affected device with a currently supported router. If replacement is not possible, restrict network access to the device's web management interface to trusted sources only.

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 web management interface (typically at 192.168.0.1) and check the status or device info page for the model number, or physically inspect the device label.
    Affected if The device model shows DIR600L
  2. Verify firmware version is 1.16wwb01
    In the router web interface, navigate to the Status or Management page and locate the firmware version field. The exact location varies by firmware but is typically shown under Device Info, Status, or System settings.
    Affected if The displayed firmware version reads exactly 1.16wwb01 (FW116WWb01)
  3. Confirm web management interface is active
    Attempt to access the router login page via HTTP on the LAN or WAN interface (default 192.168.0.1). Verify the page loads and shows the D-Link login or status screen.
    Affected if The web interface is reachable and responds with D-Link router pages
  4. Check if formDeviceReboot endpoint is accessible
    Send an HTTP GET or POST request to the router's formDeviceReboot function. On affected firmware, this is typically at /goform/formDeviceReboot or similar. Use a tool like curl: curl -X POST http://192.168.0.1/goform/formDeviceReboot
    Affected if The endpoint responds (even with an error) indicating the function exists and is reachable

The device is affected if it is a D-Link DIR600L router running firmware version 1.16wwb01 with an accessible web management interface.
