NVD Description
Note: Versions mentioned in the description apply only to the upstream icinga2 package and not the icinga2 package as distributed by Debian.
See How to fix? for Debian:13 relevant fixed versions and status.
Icinga is a monitoring system which checks the availability of network resources, notifies users of outages, and generates performance data for reporting. The TLS certificate validation in all Icinga 2 versions starting from 2.4.0 was flawed, allowing an attacker to impersonate both trusted cluster nodes as well as any API users that use TLS client certificates for authentication (ApiUser objects with the client_cn attribute set). This vulnerability has been fixed in v2.14.3, v2.13.10, v2.12.11, and v2.11.12.
