D-Link DIR-300 Router vulnerability
D-Link DIR-300 routers store passwords in cleartext, allowing attackers with access to obtain sensitive authentication credentials and compromise network security.
Verdict
Today item — known-exploited.
An authenticated or local attacker can read stored passwords from the DIR-300 router's configuration, gaining access to administrative functions and potentially pivoting to connected network resources.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
3 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 2022-09-08).
Probability (EPSS)
EPSS 0.03128 — 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-300 Router. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-310 CWE-310 — weakness family: Cryptography.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 gain physical or remote access to the router's configuration files or management interface.
Business
Network perimeter security is compromised when router credentials are exposed.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I extract plaintext passwords stored in the device memory or configuration.
Business
Administrative access to network infrastructure is lost to unauthorized parties.
3
Lateral reach — past segmentation narrative 3
Attacker
I use the obtained credentials to reconfigure the router or access connected systems.
Business
Attackers can redirect traffic, intercept communications, or launch further attacks on the internal network.
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.
