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
Improper neutralization of special elements results in a SQL Injection vulnerability in Riello Netman 204. It is only limited to the SQLite database of measurement data.This issue affects Netman 204: through 4.05.

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 Riello Netman 204 allows attackers to inject malicious SQL queries through unsanitized input. The vulnerability is present in the web interface or API handling measurement data and is limited to the SQLite database storing this data. Affected versions include all releases through version 4.05.

MitigationApply vendor patch when available. If no patch exists, implement strict input validation and parameterized queries/prepared statements for all database interactions. Consider network segmentation to limit exposure of the affected interface.

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 device model
    Check the device label or web interface for the exact model name - look for 'Riello Ups Netman 204' or similar branding
    Affected if The device is not a Riello Netman 204 model
  2. Determine the firmware version
    Access the device web interface status page or check the firmware version via SNMP/CLI interface. Compare against the affected range: all versions through 4.05
    Affected if Firmware version is 4.05 or lower, or if the version cannot be determined but the device is a Netman 204
  3. Verify web interface or API accessibility
    Check network configuration to determine if the device web interface or API ports (typically HTTP/HTTPS on ports 80/443 or vendor-specific ports) are accessible from network segments
    Affected if The web interface or API is exposed to untrusted networks and the firmware is version 4.05 or lower
  4. Confirm measurement data feature is in use
    Review device configuration to see if measurement data collection or monitoring features that feed into the web interface or API are enabled
    Affected if Measurement data features are active and the firmware is version 4.05 or lower

The environment is affected if the device is a Riello Netman 204 with firmware version 4.05 or lower and the web interface/API handling measurement data is accessible.

Upgrade available Upgrade to a release after 4.05
Interim mitigation

Apply vendor patch when available. If no patch exists, implement strict input validation and parameterized queries/prepared statements for all database interactions. Consider network segmentation to limit exposure of the affected interface.

Recommended fix Moderate confidence

Contact vendor for fixed firmware version > 4.05

  1. 1. Contact Riello UPS/Netman vendor support to confirm the availability of a fixed firmware version for the Netman 204 device.
  2. 2. If a newer firmware version is available, request the specific version number and release notes.
  3. 3. Before upgrading, back up the current device configuration if possible.
  4. 4. Follow the vendor's official firmware upgrade procedure, typically involving uploading the firmware file through the device's web interface or CLI.
  5. 5. After upgrade, verify the device is functioning correctly and the vulnerability is resolved.
  6. 6. If no fixed firmware is available, implement network segmentation to isolate the device and restrict access to trusted users only via firewall rules.
Caveat Firmware upgrades on network devices may introduce compatibility changes; review release notes and test in non-production environment first
