XI: Improper Privilege Management
CVE-2024-13997 is a high-severity improper privilege management vulnerability in XI from Nagios, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists version 2024R1.1.3 as the first without the flaw, so updating XI to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.21% chance of exploitation within 30 days, higher than 69% of scored CVEs.
High severity with no evidence of exploitation so far.

Official description
Nagios XI versions prior to 2024R1.1.3 contain a privilege escalation vulnerability in which an authenticated administrator could leverage the Migrate Server feature to obtain root privileges on the underlying XI host. By abusing the migration workflow, an admin-level attacker could execute actions outside the intended security scope of the application, resulting in full control of the operating system.

The underlying weakness: Improper Privilege Management
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
