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
Opmantek NMIS before 8.5.12G has XSS via SNMP.

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

Opmantek NMIS before version 8.5.12G contains a cross-site scripting (XSS) vulnerability that allows injection of malicious scripts through SNMP data inputs.

MitigationUpdate NMIS to version 8.5.12G or later to obtain the patched version that addresses this XSS vulnerability.

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 NMIS installation
    Locate the NMIS installation directory or check for the presence of NMIS web interface files and binaries (typically in /usr/local/nmis, /opt/nmis, or similar paths). Look for the 'nmis' command-line tool in the system PATH.
    Affected if NMIS software is installed on the system
  2. Determine installed NMIS version
    Run the command to check NMIS version, commonly 'nmis -v' or 'nmis --version', or inspect the version file in the NMIS installation directory (often named version.info, VERSION, or displayed in the web interface footer).
    Affected if The installed version is 8.5.10g or any earlier version (versions prior to 8.5.12G are affected)
  3. Verify SNMP data collection is configured
    Examine the NMIS configuration files (typically nmis.conf or similar) for SNMP-related configuration sections. Check if SNMP collectors, traps, or data inputs are enabled in the configuration.
    Affected if SNMP data collection, traps, or input modules are enabled and configured in NMIS
  4. Inspect SNMP input handling for XSS filters
    Review the SNMP input processing code or configuration to determine if input validation and XSS filtering are applied to SNMP data before display or storage. Look for sanitization routines in SNMP-related CGI or perl modules.
    Affected if SNMP data inputs are processed without proper XSS input validation or sanitization

A user is affected if Opmantek NMIS is installed with version 8.5.10g or earlier and has SNMP data collection or input features enabled.
