Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability in SonicWall Email Security appliance allow an unauthenticated user to perform remote code execution. This vulnerability affected Email Security Appliance version 10.0.2 and earlier.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAn unauthenticated remote code execution vulnerability in SonicWall Email Security appliance versions 10.0.2 and earlier allows attackers to execute arbitrary code on the affected system without any authentication credentials.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify SonicWall Email Security versionLog into the SonicWall Email Security administrative web interface and navigate to the About or System Status page to view the firmware/appliance version. Alternatively, check the product label or system information within the appliance management console.Affected if The displayed version is 10.0.2 or earlier (any version <= 10.0.2)
-
Confirm the product is directly accessibleDetermine if the SonicWall Email Security web management interface is reachable from network locations outside the trusted internal network. Attempt to access the login page from an untrusted host or review firewall rules governing access to the appliance.Affected if The appliance administrative interface is exposed to untrusted or public networks without proper access controls
-
Verify authentication is required for the web interfaceAttempt to access the SonicWall Email Security login page from an unauthenticated state and confirm that the appliance requires valid credentials before allowing access to administrative functions.Affected if The interface allows unauthenticated access to certain endpoints or functions (the vulnerability specifically allows unauthenticated RCE)
If the installed SonicWall Email Security version is 10.0.2 or earlier and the appliance is network-accessible, the system is vulnerable to unauthenticated remote code execution.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImmediately restrict network access to the SonicWall Email Security appliance from untrusted networks and upgrade to a patched version beyond 10.0.2 as soon as vendor-supplied updates become available.
