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
Nagios XI versions prior to 2024R1 are vulnerable to cross-site scripting (XSS) via the Graph Explorer component. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.

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

Nagios XI versions before 2024R1 contain a stored cross-site scripting (XSS) vulnerability in the Graph Explorer component. Attackers can inject malicious JavaScript through insufficiently validated user-supplied input, which then executes in the context of other users' browsers when they view the affected content.

MitigationUpgrade to Nagios XI 2024R1 or later to obtain the patched version that properly sanitizes user input in the Graph Explorer component.

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. Check Nagios XI version
    Navigate to Admin > System Information in the Nagios XI web interface, or run: cat /usr/local/nagiosxi/etc/xi-sys.cfg 2>/dev/null | grep -i version
    Affected if The installed version is before 2024R1 (versions shown as 2023.x, 2022.x, etc.)
  2. Verify Graph Explorer component is installed
    Check if Graph Explorer is available in the web interface under the Reports or Monitoring menu, or list installed components: ls /usr/local/nagiosxi/html/includes/components/ 2>/dev/null | grep -i graphexplorer
    Affected if Graph Explorer component is present and accessible to users
  3. Identify users with Graph Explorer access
    Review user permissions in Admin > User Management > Manage Users / User Groups to see which users have access to Graph Explorer functionality
    Affected if Multiple users have access to Graph Explorer, increasing exposure to stored XSS
  4. Inspect Graph Explorer configurations for injected content
    Query the Nagios XI database for Graph Explorer configurations: mysql -u nagiosxi -p<npass> nagiosxi -e "SELECT * FROM nagios_graph_explorer" 2>/dev/null or check /usr/local/nagiosxi/var/spool/ for stored Graph Explorer data
    Affected if Any Graph Explorer configurations contain unsanitized HTML/script tags in user-supplied fields

You are affected if Nagios XI is running a version before 2024R1 AND the Graph Explorer component is enabled and accessible to users.

Generated from the published advisory. Verify against your own configuration.
