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 2024R1.2.2 has an Information Disclosure vulnerability, which allows unauthenticated users to access multiple pages displaying the usernames and email addresses of all current users.

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

Nagios XI 2024R1.2.2 contains an information disclosure vulnerability where unauthenticated users can access multiple pages that expose the usernames and email addresses of all registered users in the system.

MitigationApply vendor-provided patch or update to a patched version of Nagios XI. Until then, consider restricting network access to the Nagios XI web interface to trusted IPs or implementing additional authentication layers.

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 installed Nagios XI version
    Access the Nagios XI web interface and navigate to the Admin > System Information page, or run the version check script at /usr/local/nagiosxi/scripts/get_version.sh if available on the server
    Affected if The installed version is 2024R1.2.2 or any 2024 release (year-based versioning)
  2. Confirm web interface accessibility
    Attempt to access the Nagios XI login page from an unauthenticated browser session or using a tool like curl without providing credentials
    Affected if The web interface returns a login page or allows any unauthenticated access without redirecting to an authentication error
  3. Test for unauthenticated user enumeration endpoints
    Use a tool like curl or a browser to access common Nagios XI endpoints that might expose user data, checking HTTP response codes and content for usernames or email addresses without logging in
    Affected if Any HTTP endpoint returns user account information such as usernames, email addresses, or user lists without requiring authentication
  4. Inspect HTTP responses for sensitive data exposure
    Review raw HTTP responses from various Nagios XI pages accessed without authentication, searching for email addresses in the format [email protected] or user account details
    Affected if The HTTP responses contain email addresses or full usernames of registered users without having authenticated

If running Nagios XI version 2024 and the web interface allows unauthenticated access to pages that display user email addresses or usernames, the environment is affected by this CVE.
