** 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.

  • Exploit arrives as an HTTP POST request to /hedwig.cgi; inspect the request body for the path traversal string containing '/htdocs/webinc/getcfg' followed by a '.xml' filename within 50 bytes.
  • The attack manipulates the 'service' POST argument with a path traversal payload targeting XML configuration files under /htdocs/webinc/getcfg/; monitor for this argument pattern in POST bodies to /hedwig.cgi.
  • Successful exploitation leaks session data; monitor for unexpected session token exposure or privilege escalation following POST requests to /hedwig.cgi.
  • The Snort/ET rule (sid:2055723) is classified as plaintext-only (tls_state plaintext); deploy at the network perimeter and internally to catch unencrypted exploitation attempts.
  • ·The vulnerability is a perma-vuln on an EOL/EOS device with no vendor patch available; the D-Link DIR-859 (firmware 1.06B01) will never receive a fix. Detection and network isolation are the only mitigations.
  • ·CISA's KEV remediation due date is 2025-07-16; organizations still running this device must retire and replace it per vendor instructions as no software fix exists.
