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 · unedited
A vulnerability in GMS allow unauthenticated user to SQL injection in Webservice module. This vulnerability affected GMS versions GMS 8.4, 8.5, 8.6, 8.7, 9.0 and 9.1.

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 confidence

An unauthenticated SQL injection vulnerability in the GMS Webservice module allows remote attackers to inject malicious SQL queries without any authentication. This critical flaw (CVSS 9.8) affects GMS versions 8.4 through 9.1 and could enable full database compromise, data exfiltration, or potentially remote code execution depending on database configuration.

MitigationUpgrade to a patched GMS version if available; otherwise deploy WAF rules to filter SQL injection payloads and restrict external access to the Webservice module until a fix can be applied.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Sonicwall GMS is installed
    Locate GMS installation directories or check system inventory for Sonicwall Global Management System software
    Affected if GMS software is found on the system
  2. Check installed GMS version
    Use system inventory tools, package manager, or GMS admin interface to determine the exact version number
    Affected if Installed version matches 8.4, 8.5, 8.6, 8.7, 9.0, or 9.1
  3. Verify Webservice module status
    Examine GMS configuration files or admin interface to confirm whether the Webservice module is enabled and accessible
    Affected if Webservice module is enabled and exposed to network
  4. Assess network exposure of Webservice interface
    Review firewall rules, network access controls, or reverse proxy configuration to determine if GMS Webservice port is reachable from external networks
    Affected if Webservice module is reachable from untrusted networks without authentication

Environment is affected if Sonicwall GMS versions 8.4 through 9.1 are installed with the Webservice module enabled and exposed to network access.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to a patched GMS version if available; otherwise deploy WAF rules to filter SQL injection payloads and restrict external access to the Webservice module until a fix can be applied.

Recommended fix Moderate confidence

GMS 9.2 or later

  1. Identify the current GMS version running in your environment
  2. Download the latest GMS version (9.2 or later) from the official SonicWall support portal
  3. Review release notes for any migration or upgrade prerequisites
  4. Back up the current GMS configuration and database
  5. Stop the GMS services before upgrading
  6. Install the updated GMS version following the official upgrade documentation
  7. Restart GMS services and verify the application is functioning normally
  8. Confirm the Webservice module is operational and the SQL injection vulnerability is remediated
Caveat Review upgrade documentation for any configuration changes or migration requirements from your current version
