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 SQL Injection vulnerability was discovered in the Alert functionality due to improper validation of an input parameter. An authenticated user with limited privileges can execute arbitrary SQL statements on the DBMS used by the web application, potentially exposing unauthorized data, altering their structure and content, and/or affecting their availability.

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 · moderate confidence

SQL injection vulnerability in the Alert functionality allows authenticated users with limited privileges to execute arbitrary SQL statements due to improper input validation of a specific parameter. This can lead to unauthorized data exposure, database manipulation, and potential system compromise.

MitigationImplement parameterized queries (prepared statements) and strict input validation/sanitization for all user-supplied parameters in the Alert functionality. Apply principle of least privilege to database accounts.

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 the installed Nozominetworks product
    Run the command to check the product version: 'cmc --version' for CMC or 'guardian --version' for Guardian. Alternatively, check the web UI footer or the about section in the administration panel.
    Affected if The version displayed is lower than 25.2.0
  2. Confirm the product type
    Determine whether the deployment uses Nozominetworks CMC (central management console) or Guardian (standalone sensor). Check the product name in the web UI header or system information page.
    Affected if The product is Nozominetworks CMC or Guardian with version below 25.2.0
  3. Verify the Alert functionality is accessible
    Log into the web interface and navigate to the Alert configuration or monitoring section. Check if alerts can be created, viewed, or modified through the UI or API endpoint.
    Affected if The Alert feature is enabled and accessible to authenticated users (even those with limited privileges)
  4. Check user privilege configuration
    Review the user roles and permissions configured in the administration panel. Identify if low-privilege or read-only users can access the Alert functionality.
    Affected if Users with limited or non-administrative privileges have access to the Alert functionality

You are affected if your Nozominetworks CMC or Guardian version is below 25.2.0 and the Alert functionality is accessible to authenticated users.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

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.

Upgrade available Upgrade to 25.2.0 or later
Fixed in 25.2.0
Interim mitigation

Implement parameterized queries (prepared statements) and strict input validation/sanitization for all user-supplied parameters in the Alert functionality. Apply principle of least privilege to database accounts.

Recommended fix High confidence

25.2.0 (for both CMC and Guardian products)

  1. 1. Identify all deployed instances of CMC and Guardian products in the environment
  2. 2. Check current installed versions of each affected product
  3. 3. For each instance running a version lower than 25.2.0, obtain the upgrade package from the official Nozomi Networks vendor repository or support channel
  4. 4. Review Nozomi Networks upgrade documentation for CMC and Guardian respectively
  5. 5. Perform the upgrade following vendor-provided procedures, including any pre-upgrade backup steps
  6. 6. Verify the upgrade was successful by confirming the new version is 25.2.0 or later
  7. 7. Test the Alert functionality to confirm the SQL injection vulnerability is remediated
