TP-Link Multiple Archer Devices vulnerability
Directory traversal vulnerability in TP-Link Archer devices allows remote attackers to read arbitrary files via path traversal sequences in login requests.
Verdict
Today item — known-exploited.
A path traversal flaw in multiple TP-Link Archer devices enables unauthenticated remote file access. The high EPSS score and confirmed wild exploitation indicate active abuse risk. Affected devices require immediate patching.

1 independent public report 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 2022-03-25).
Probability (EPSS)
EPSS 0.83667 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) · Affected: TP-Link, Multiple Archer Devices. Confirm exact fixed builds in the vendor advisory.CVSS — CISA-assigned via the ADP container (CVE.org), version 3.1; the CNA left no metrics, so CISA's own score is used ahead of NVD.
Weakness (CWE)
Mapped to CWE-22 Path Traversal — weakness family: Path traversal / file.CWE assignment from the public NVD record (may be stale); the weakness class drives how the flaw is exploited.
CISA SSVC (triage disposition)
Exploitation: active · Automatable: yes · Technical Impact: partialCISA's own stakeholder-specific triage inputs, published in the CVE record (CISA Coordinator role). NOTE: this is CISA's three decision points; the final Act/Attend/Track decision also requires a Mission & Well-being input not published here, so no overall decision is asserted.
Currency of the record
CISA added this to its KEV catalog 2534 days after the CVE record was published.KEV lag = CISA-KEV dateAdded − CVE.org datePublished; a floor on how long the known-exploited flaw sat in the public record before the federal catalog listed it. Severity/weakness here is CNA- or CISA-assigned (current at disclosure), independent of NVD's analysis backlog.

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 HTTP requests with ../ sequences in the PATH_INFO parameter to the login endpoint, bypassing directory restrictions and accessing sensitive files outside the intended web root.
Business
Sensitive configuration files, credentials, or system information stored on the device become accessible to attackers without authentication, compromising device security posture.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I extract device credentials or authentication tokens from traversed files to escalate privileges or maintain persistent access to the compromised device.
Business
Attackers gain administrative control of networking infrastructure, enabling lateral movement, traffic interception, or deployment of malware across connected networks.
3
Lateral reach — past segmentation narrative 3
Attacker
I enumerate and exfiltrate system files to identify additional vulnerabilities or misconfigurations for further exploitation.
Business
The device becomes a pivot point for broader network compromise, increasing exposure of connected systems and data to unauthorized access.
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.
