Description

Icinga DB Web provides a graphical interface for Icinga monitoring. Starting in version 1.2.0 and prior to version 1.2.2, users with access to Icinga Dependency Views, are allowed to see hosts and services that they weren't meant to on the dependency map. However, the name of an object will not be revealed nor does this grant access to a host's or service's detail view. Please note that this only affects the restrictions `filter/hosts` and `filter/services`. `filter/objects` is not affected by this and restricts objects as it is supposed to. Version 1.2.2 applies these restrictions properly. As a workaround, one may downgrade to version 1.1.3.

Affected products

• icingadb-web: from 1.2.0 before 1.2.2 — fixed in 1.2.2

How to fix

Upgrade to a fixed version: icingadb-web 1.2.2. Check the vendor advisory for mitigations.
