CVE-2023-48082
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 · uneditedNagios XI before 2024R1 was discovered to improperly handle API keys generation (randomly-generated), allowing attackers to possibly generate the same set of API keys for all users and utilize them to authenticate.
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 confidenceNagios XI before 2024R1 uses a flawed random number generator for API key creation, allowing attackers to predict or reproduce valid API keys. This enables unauthorized authentication as any user whose keys can be predicted.

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 Nagios XI versionLocate the installed version of Nagios XI through the admin interface (typically under Help > About) or by checking system filesAffected if The installed version is before 2024R1 or exactly version 2014
-
Confirm API functionality is activeDetermine whether the Nagios XI API feature is enabled and in use within the environmentAffected if API functionality is enabled and API keys exist in the system
-
Verify API key generation methodReview system documentation or logs for information about how API keys were generatedAffected if API keys were generated by the affected (flawed) random number generator and have not been regenerated since upgrading to 2024R1
A user is affected if their Nagios XI installation is version 2014 or any version prior to 2024R1 AND the system uses API keys for authentication.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped2014
Upgrade to Nagios XI 2024R1 or later which implements cryptographically secure random API key generation.
Nagios XI 2024R1 or later
- 1. Back up your current Nagios XI installation including the database and configuration files.
- 2. Download the latest Nagios XI version (2024R1 or later) from the official Nagios website (www.nagios.com).
- 3. Follow Nagios XI upgrade documentation to install the updated version.
- 4. After upgrade, regenerate all existing API keys to ensure new cryptographically secure keys are generated.
- 5. Verify the upgrade was successful by checking the Nagios XI version and testing API key functionality.
