# Pre-authentication deserialization of untrusted data vulnerability has been identified in the SMA1000 Appliance…

SonicWall SMA1000 appliances have a deserialization flaw in the Appliance Management Console and Central Management Console that lets a remote, unauthenticated attacker run arbitrary OS commands. CISA lists it as actively exploited in the wild, with ransomware use noted in the sources.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:SonicWall SMA1000 Appliances affected ? fixed ?
- vendor:sonicwall sma8200v affected < 12.4.3-02854 fixed 12.4.3-02854
- vendor:sonicwall sma6200 firmware affected < 12.4.3-02854 fixed 12.4.3-02854
- vendor:sonicwall sma6210 firmware affected < 12.4.3-02854 fixed 12.4.3-02854
- vendor:sonicwall sma7200 firmware affected < 12.4.3-02854 fixed 12.4.3-02854
- vendor:sonicwall sma7210 firmware affected < 12.4.3-02854 fixed 12.4.3-02854
- vendor:sonicwall sra ex6000 firmware affected <= 12.4.3-02804 fixed ?
- vendor:sonicwall sra ex7000 firmware affected <= 12.4.3-02804 fixed ?
- vendor:sonicwall sra ex9000 firmware affected <= 12.4.3-02804 fixed ?

## Fix

Apply the mitigations per SonicWall vendor instructions; if mitigations are unavailable, discontinue use of the product (per CISA). Fixed version: unknown.

## From the sources

SonicWall SMA1000 Appliance Management Console (AMC) and Central Management Console (CMC) contain a deserialization of untrusted data vulnerability, which can enable a remote, unauthenticated attacker to execute arbitrary OS commands.

CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
