SonicWall SMA100 vulnerability
SonicWall SMA100 contains an unauthenticated SQL injection vulnerability (CWE-89) enabling read-only access to unauthorized data. Actively exploited in the wild and associated with ransomware campaigns.
Verdict
Today item, not a backlog item.
An unauthenticated attacker can exploit SQL injection in SonicWall SMA100 to extract sensitive information without authentication. High EPSS score (0.94) and confirmed wild exploitation indicate immediate risk, particularly in ransomware-driven reconnaissance operations.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
13 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 2021-11-03), flagged for known ransomware use.
Probability (EPSS)
EPSS 0.99906 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: SonicWall, SMA100. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-89 SQL 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 craft malicious SQL queries in unauthenticated requests to SMA100 endpoints to bypass access controls.
Business
Sensitive configuration data, credentials, or user information stored in the appliance database becomes accessible to unauthenticated threat actors.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I extract database contents to identify high-value targets, network topology, and authentication mechanisms within the organization.
Business
Reconnaissance data enables targeted lateral movement and privilege escalation attacks against critical infrastructure protected by the SonicWall appliance.
3
Lateral reach — past segmentation narrative 3
Attacker
I use harvested credentials and network intelligence to establish persistent access or deploy ransomware payloads.
Business
Ransomware operators gain foothold for encryption attacks, resulting in operational downtime, data loss, and extortion demands.
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.
