NVD Description

Note: Versions mentioned in the description apply only to the upstream icinga2 package and not the icinga2 package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

Icinga 2 is an open source monitoring system. From 2.8 until 2.14.9, 2.15.4, and 2.16.2, certificate update JSON-RPC message handling does not validate that the sender is a trusted endpoint. An unauthenticated network attacker able to connect to TCP port 5665 can replace the node certificate and trusted CA certificate, impersonate a trusted node, and take control of the node. This issue is fixed in versions 2.14.9, 2.15.4, and 2.16.2.
