CVE-2022-4259
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 · uneditedDue to improper input validation in the Alerts controller, a SQL injection vulnerability in Nozomi Networks Guardian and CMC allows an authenticated attacker to execute arbitrary SQL queries on the DBMS used by the web application.
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 confidenceA SQL injection vulnerability exists in the Alerts controller of Nozomi Networks Guardian and CMC due to improper input validation. An authenticated attacker can exploit this to execute arbitrary SQL queries on the application's database, potentially leading to data exfiltration, modification, or complete database compromise.

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 the installed Nozomi Networks productCheck the product type - determine if running Nozomi Networks Guardian or Nozomi Networks CMC. This is typically visible in the product UI, license information, or system diagnostics.Affected if Running either Guardian or CMC product line
-
Determine the installed versionLocate the version information for the installed product. This is usually found in the system settings, about page, or via CLI commands provided by the product documentation.Affected if Version is below 22.5.2 for either product
-
Verify the Alerts controller is accessibleConfirm the Alerts functionality is enabled and accessible in the installation. The Alerts controller is part of the web interface/API functionality.Affected if Alerts controller is active and accessible to authenticated users
You are affected if you are running Nozomi Networks Guardian or CMC with a version lower than 22.5.2 and the Alerts controller is accessible to authenticated users.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped22.5.2
Implement proper input validation and use parameterized queries (prepared statements) in the Alerts controller to prevent SQL injection. Apply vendor-provided patches as soon as they become available.
22.5.2
- Back up the current Guardian or CMC configuration and database before upgrading
- Download Nozomi Networks Guardian or CMC version 22.5.2 (or later) from the official Nozomi Networks support portal at security.nozominetworks.com
- Apply the upgrade following the standard Nozomi Networks upgrade procedure for your deployment type
- After upgrade, verify the Alerts controller functionality and confirm the system is operational
- Verify the version number reflects 22.5.2 or later
