D-Link DIR-859 Router vulnerability
D-Link DIR-859 routers contain a path traversal vulnerability in /hedwig.cgi that allows attackers to read sensitive configuration files, potentially enabling privilege escalation and unauthorized device control.
Verdict
Today item — known-exploited.
A path traversal flaw in the HTTP POST handler of legacy D-Link DIR-859 routers permits unauthenticated file access via manipulated service parameters, exposing session data and configuration secrets. The product is end-of-life with no vendor patches available.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
7 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2025-06-25).
Probability (EPSS)
EPSS 0.82714 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: D-Link, DIR-859 Router. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-22 Path Traversal — weakness family: Path traversal / file.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a malicious HTTP POST request to /hedwig.cgi with a traversal payload in the service parameter to escape the intended directory.
Business
Attackers gain unauthorized read access to sensitive router configuration and session files without authentication.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I extract session tokens and authentication credentials from exposed configuration files like DHCPS6.BRIDGE-1.xml.
Business
Compromised credentials enable lateral movement and privilege escalation within the device and connected network.
3
Lateral reach — past segmentation narrative 3
Attacker
I use obtained credentials to authenticate to administrative interfaces and modify router settings or inject malicious configurations.
Business
Complete device compromise allows traffic interception, DNS hijacking, and network-wide compromise of connected systems.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
