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
The affected On-Premise cnMaestro is vulnerable to a pre-auth data exfiltration through improper neutralization of special elements used in an SQL command. This could allow an attacker to exfiltrate data about other user’s accounts and devices.

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

On-Premise cnMaestro contains a pre-authentication SQL injection vulnerability where improper neutralization of special elements in SQL commands allows unauthenticated attackers to exfiltrate sensitive data about other user accounts and associated devices.

MitigationApply vendor-provided security patch immediately; until patch is available, restrict network access to cnMaesto management interface to minimize exposure.

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 cnMaestro version
    Access the cnMaestro web interface and navigate to the About or System Information page, or use the CLI command 'show version' if available via SSH or console
    Affected if The displayed version is exactly 2.4.2, 3.0.0, or 3.0.3
  2. Confirm management interface accessibility
    Determine if the cnMaestro HTTP/HTTPS management ports are reachable from untrusted network segments by reviewing firewall rules or attempting external connectivity tests
    Affected if The management interface is exposed to networks outside the trusted administrative zone
  3. Review application logs for SQL injection indicators
    Examine cnMaestro server logs (typically found in /var/log/ or the cnMaestro logs directory) for unusual SQL syntax in request parameters, database errors, or unexpected authentication attempts
    Affected if Logs contain SQL error messages, malformed SQL queries, or evidence of unauthorized data access patterns

You are affected if your cnMaestro installation is version 2.4.2, 3.0.0, or 3.0.3 and the management interface is network-accessible to untrusted parties, since this is a pre-authentication SQL injection flaw.
