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 in Nozomi Networks Guardian and CMC, due to improper input validation in certain fields used in the Asset Intelligence functionality of our IDS, may allow an unauthenticated attacker to execute arbitrary SQL statements on the DBMS used by the web application by sending specially crafted malicious network packets. Malicious users with extensive knowledge on the underlying system may be able to extract arbitrary information from the DBMS in an uncontrolled way, alter its structure and data, and/or affect its 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 · high confidence

SQL injection vulnerability in Nozomi Networks Guardian and CMC's IDS Asset Intelligence functionality allows unauthenticated attackers to execute arbitrary SQL statements via specially crafted malicious network packets due to improper input validation in certain fields.

MitigationApply vendor-provided patches for Guardian and CMC; implement strict input validation and parameterized queries in the affected Asset Intelligence fields; consider WAF deployment as additional layer of protection.

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 your Nozomi product type
    Determine whether the system is Nozomi Networks Guardian or CMC (Central Management Console) - this can typically be found in the product UI header, about page, or system information section
    Affected if The product is either Guardian or CMC
  2. Check installed version against affected ranges
    Locate the installed version number in the product's system information, about page, or CLI (commonly via 'version' or 'show version' command). Compare it to the affected ranges: 22.6.0 through 22.6.2, or 23.0.0
    Affected if The installed version falls within >= 22.6.0 and < 22.6.3, OR >= 23.0.0 and < 23.1.0
  3. Verify IDS Asset Intelligence module status
    Check whether the IDS (Intrusion Detection System) Asset Intelligence functionality is enabled or configured on the appliance. This is typically found in the IDS/Asset settings, monitoring configuration, or intelligence feature toggles within the product UI
    Affected if IDS Asset Intelligence is actively enabled or configured on the system
  4. Review network logs for SQL injection indicators
    Examine IDS/asset intelligence network logs, SQL database logs, or security event logs for unusual or malformed SQL statements, unexpected database queries, or signs of injection attempts arriving via network packets
    Affected if Suspicious SQL-like patterns or unauthorized database queries are present in the logs
  5. Audit database for unauthorized changes or anomalies
    Review the underlying database (PostgreSQL or similar) for unexpected tables, unauthorized records in asset tables, or SQL statements that were not originated from legitimate application code
    Affected if Database contains unexpected changes, unauthorized records, or evidence of arbitrary SQL execution

A system is affected if it is Nozomi Networks Guardian or CMC with a version in the listed ranges AND the IDS Asset Intelligence feature is enabled, making it vulnerable to unauthenticated SQL injection via specially crafted network packets.

Upgrade available Upgrade to 22.6.3 / 23.1.0 or later
Fixed in 22.6.323.1.0
Interim mitigation

Apply vendor-provided patches for Guardian and CMC; implement strict input validation and parameterized queries in the affected Asset Intelligence fields; consider WAF deployment as additional layer of protection.

Recommended fix High confidence

22.6.3 or 23.1.0 (depending on current branch)

  1. Identify the currently installed version of Nozomi Networks Guardian or CMC by checking the system management interface or using the command line tool
  2. If running version 22.6.0, 22.6.1, or 22.6.2: Upgrade to version 22.6.3
  3. If running version 23.0.0 through 23.0.x: Upgrade to version 23.1.0
  4. Follow the standard upgrade procedure documented in the Nozomi Networks installation guide, ensuring to backup the system before upgrading
  5. After upgrade, verify the Asset Intelligence functionality is working correctly
