CVE-2025-60556
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 · uneditedD-Link DIR600L Ax FW116WWb01 was discovered to contain a buffer overflow via the curTime parameter in the function formSetWizard1.
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 · high confidenceD-Link DIR600L Ax firmware FW116WWb01 contains a buffer overflow vulnerability in the formSetWizard1 function where the curTime parameter lacks proper bounds checking, allowing an attacker to overflow a fixed-size buffer with excessive data. This is a classic stack-based buffer overflow in the router's web management interface that could allow remote code execution or denial of service.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the firmware versionAccess the router's web management interface (typically at 192.168.0.1) and navigate to the Status or System section to view the firmware version. Alternatively, use the router's admin CLI if available and run: cat /proc/version or look for version info in the web UI source.Affected if The firmware version displayed is 1.16wwb01 exactly, indicating the specific affected release.
-
Confirm web management interface is accessibleAttempt to reach the router's web interface via HTTP or HTTPS on the LAN or WAN IP address. Check if the login page or formSetWizard1 endpoint responds.Affected if The web management interface is reachable, which is required for exploiting the buffer overflow in the formSetWizard1 function.
-
Check if remote administration is enabledIn the router's web UI, go to the Administration or Management settings section. Look for options such as 'Remote Management', 'Remote Access', or 'Web Management Access' that control whether the interface is accessible from the WAN side.Affected if Remote administration is enabled, meaning the vulnerable web interface is exposed beyond the local network.
-
Verify the formSetWizard1 function existsIf you have access to the router firmware binary or can inspect the web UI code, search for the 'formSetWizard1' function name. This function handles the curTime parameter that lacks bounds checking.Affected if The formSetWizard1 function is present in the firmware, which is the vulnerable component described in this CVE.
You are affected if your D-Link DIR600L runs firmware version 1.16wwb01 AND the web management interface (especially the formSetWizard1 handler) is accessible, either locally or remotely.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor firmware updates when available; until then, disable remote web management, restrict administrative access to trusted IPs only, and monitor for exploitation attempts.
