Security update for icinga2
This update for icinga2 fixes the following issues:
icinga2 was updated to 2.12.5:
Version 2.12.5 fixes two security vulnerabilities that may lead to privilege escalation for authenticated API users. Other improvements include several bugfixes related to downtimes, downtime notifications, and more reliable connection handling.
-
Security
-
Don't expose the PKI ticket salt via the API. This may lead to privilege escalation for authenticated API users by them being able to request certificates for other identities (CVE-2021-32739)
-
Don't expose IdoMysqlConnection, IdoPgsqlConnection, and ElasticsearchWriter passwords via the API (CVE-2021-32743)
Depending on your setup, manual intervention beyond installing the new versions may be required, so please read the more detailed information in the release blog post carefully.

Описание
Icinga 2 v2.8.0 through v2.11.7 and v2.12.2 has an issue where revoked certificates due for renewal will automatically be renewed, ignoring the CRL. This issue is fixed in Icinga 2 v2.11.8 and v2.12.3.

Описание
Icinga is a monitoring system which checks the availability of network resources, notifies users of outages, and generates performance data for reporting. From version 2.4.0 through version 2.12.4, a vulnerability exists that may allow privilege escalation for authenticated API users. With a read-ony user's credentials, an attacker can view most attributes of all config objects including `ticket_salt` of `ApiListener`. This salt is enough to compute a ticket for every possible common name (CN). A ticket, the master node's certificate, and a self-signed certificate are enough to successfully request the desired certificate from Icinga. That certificate may in turn be used to steal an endpoint or API user's identity. Versions 2.12.5 and 2.11.10 both contain a fix the vulnerability. As a workaround, one may either specify queryable types explicitly or filter out ApiListener objects.

Описание
Icinga is a monitoring system which checks the availability of network resources, notifies users of outages, and generates performance data for reporting. In versions prior to 2.11.10 and from version 2.12.0 through version 2.12.4, some of the Icinga 2 features that require credentials for external services expose those credentials through the API to authenticated API users with read permissions for the corresponding object types. IdoMysqlConnection and IdoPgsqlConnection (every released version) exposes the password of the user used to connect to the database. IcingaDB (added in 2.12.0) exposes the password used to connect to the Redis server. ElasticsearchWriter (added in 2.8.0)exposes the password used to connect to the Elasticsearch server. An attacker who obtains these credentials can impersonate Icinga to these services and add, modify and delete information there. If credentials with more permissions are in use, this increases the impact accordingly. Starting with the 2.11.10 and 2.12.5 releases, these passwords are no longer exposed via the API. As a workaround, API user permissions can be restricted to not allow querying of any affected objects, either by explicitly listing only the required object types for object query permissions, or by applying a filter rule.
