SonicWall SMA100 vulnerability
SonicWall SMA100 contains an unauthenticated directory traversal vulnerability in the handleWAFRedirect CGI that allows attackers to test for file presence on the server.
Verdict
Today item — known-exploited.
An unauthenticated remote attacker can exploit path traversal in SMA100's handleWAFRedirect CGI to enumerate files and directories on the affected system without authentication, potentially revealing sensitive configuration or system information.

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 2022-03-28).
Probability (EPSS)
EPSS 0.03977 — 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: SonicWall, SMA100. 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 — CNA-assigned (CVE.org); 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 830 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 malicious path traversal sequences in the handleWAFRedirect parameter to probe for the existence of sensitive files on the target server.
Business
Attackers gain reconnaissance capability to map the server's filesystem structure and identify sensitive files before launching further attacks.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I use file presence detection to locate configuration files, credentials, or system paths that may be exploitable in subsequent attack stages.
Business
Information disclosure enables attackers to refine targeted attacks and increases the surface area for privilege escalation or data theft.
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.
