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 checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Nagios XI versionAccess 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 serverAffected if The installed version is 2024R1.2.2 or any 2024 release (year-based versioning)
-
Confirm web interface accessibilityAttempt to access the Nagios XI login page from an unauthenticated browser session or using a tool like curl without providing credentialsAffected if The web interface returns a login page or allows any unauthenticated access without redirecting to an authentication error
-
Test for unauthenticated user enumeration endpointsUse 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 inAffected if Any HTTP endpoint returns user account information such as usernames, email addresses, or user lists without requiring authentication
-
Inspect HTTP responses for sensitive data exposureReview raw HTTP responses from various Nagios XI pages accessed without authentication, searching for email addresses in the format [email protected] or user account detailsAffected 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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply 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.
