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
A vulnerability was found in D-Link DIR-825 1.08.01. This impacts the function get_ping6_app_stat of the file ping6_response.cg of the component httpd. Performing manipulation of the argument ping6_ipaddr results in buffer overflow. It is possible to initiate the attack remotely. The exploit has been made public and could be used. This vulnerability only affects products that are no longer supported by the maintainer.

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 confidence

Buffer overflow vulnerability in D-Link DIR-825 1.08.01 httpd component's get_ping6_app_stat function allows remote attackers to overflow the ping6_ipaddr argument, potentially enabling remote code execution. The vulnerability is exploitable remotely with no authentication required.

MitigationSince D-Link DIR-825 is end-of-life with no official patch, immediately isolate affected devices behind restrictive firewall rules, disable IPv6 if not required, or replace with actively supported hardware. Monitor for indicators of compromise given public exploit availability.

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 device model
    Access the device's web interface or check the physical label to confirm the model is D-Link DIR-825
    Affected if The device is not a D-Link DIR-825, the vulnerability does not apply
  2. Check the firmware version
    Log into the router's web interface and navigate to the Status or Management page to view the firmware version, or use the command line and run 'cat /proc/version' or check the firmware file name
    Affected if The firmware version is exactly 1.08.01, indicating this specific affected version
  3. Verify httpd service exposure
    Check if the httpd service is accessible from the network by attempting to reach the device's IP on port 80 or 443 from an external location, or review firewall rules and port forwarding configurations
    Affected if The httpd web interface is exposed to untrusted networks (such as the internet), making remote exploitation possible

You are affected if you own a D-Link DIR-825 device running firmware version 1.08.01 and its httpd service is network-accessible.

Mitigation

Since D-Link DIR-825 is end-of-life with no official patch, immediately isolate affected devices behind restrictive firewall rules, disable IPv6 if not required, or replace with actively supported hardware. Monitor for indicators of compromise given public exploit availability.
