D-Link DIR-645 Router vulnerability
D-Link DIR-645 routers are vulnerable to remote command execution through the HNAP interface, allowing unauthenticated attackers to execute arbitrary commands on affected devices.
Verdict
Today item — known-exploited.
This vulnerability enables direct remote code execution on network infrastructure with high exploitability. The active exploitation in the wild and high EPSS score indicate immediate risk to exposed devices, particularly in environments where routers are internet-facing.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
990 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 2022-02-10).
Probability (EPSS)
EPSS 0.97101 — 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-645 Router. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-77 Command Injection — weakness family: Injection.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 identify internet-exposed D-Link DIR-645 routers and probe the HNAP interface for the GetDeviceSettings action.
Business
Network perimeter is compromised, establishing a foothold for lateral movement into internal systems.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I craft a malicious HNAP request to execute arbitrary commands with router privileges.
Business
Router becomes a compromised network node capable of traffic interception, DNS hijacking, and credential harvesting.
3
Lateral reach — past segmentation narrative 3
Attacker
I maintain persistence by modifying router firmware or configuration to survive reboots.
Business
Long-term compromise of network infrastructure enables sustained espionage and data exfiltration.
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.
