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
All versions of NetMan 204 could allow an unauthenticated remote attacker to read a file (config.cgi) containing sensitive information, like credentials.

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

NetMan 204 contains an unauthenticated file disclosure vulnerability allowing remote attackers to read the config.cgi file, which contains sensitive credentials. This is likely a path traversal or insecure file inclusion issue in the web interface.

MitigationRestrict external access to the NetMan 204 web interface via network segmentation or firewall rules. If possible, relocate or restrict access to the config.cgi file and implement authentication. Contact vendor for patches.

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 NetMan 204 installation
    Check if the Riello UPS NetMan 204 web interface is accessible on your network by accessing the device IP or hostname on the typical HTTP/HTTPS ports (80/443). Look for the NetMan 204 login page or banner.
    Affected if The NetMan 204 web interface is present and reachable on your network.
  2. Verify config.cgi file existence
    Attempt to access the config.cgi file directly via HTTP/HTTPS without any authentication. For example: GET http://<device_ip>/cgi-bin/config.cgi or the full path as discovered in your environment.
    Affected if The config.cgi file is accessible without requiring login credentials.
  3. Check for sensitive content in config.cgi
    If config.cgi is accessible, examine the response content for plaintext credentials, SNMP community strings, user accounts, or other sensitive configuration data.
    Affected if config.cgi returns sensitive information such as usernames, passwords, community strings, or authentication tokens.
  4. Assess network exposure
    Determine whether the NetMan 204 web interface is accessible from untrusted networks (e.g., the internet or guest networks) versus being restricted to trusted management networks.
    Affected if The web interface is reachable from networks that should not have direct management access to the UPS device.

If the NetMan 204 web interface is present and the config.cgi file can be accessed without authentication to reveal sensitive credentials, the environment is affected by CVE-2022-47892.
