Nagios XI < 2024R1.1.3 Privilege Escalation via Migrate Server Feature to Root on Host
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.
Nagios addresses this vulnerability as "Nagios XI was vulnerable to a privilege escalation wherein an administrator using the Migrate Server feature could become root on the XI server."
