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.

The remote host is affected by the vulnerability described in GLSA-202412-08 (icinga2: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in Icinga2. Please review the CVE identifiers referenced     below for details.

Tenable has extracted the preceding description block directly from the Gentoo Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3725-1 advisory.

  - An issue was discovered in Icinga2 before v2.12.0-rc1. The prepare-dirs script (run as part of the icinga2     systemd service) executes chmod 2750 /run/icinga2/cmd. /run/icinga2 is under control of an unprivileged     user by default. If /run/icinga2/cmd is a symlink, then it will by followed and arbitrary files can be     changed to mode 2750 by the unprivileged icinga2 user. (CVE-2020-14004)

  - 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.
    (CVE-2020-29663)

  - Icinga is a monitoring system which checks the availability of network resources, notifies users of     outages, and generates performance data for reporting. In versions 2.5.0 through 2.13.0,     ElasticsearchWriter, GelfWriter, InfluxdbWriter and Influxdb2Writer do not verify the server's certificate     despite a certificate authority being specified. Icinga 2 instances which connect to any of the mentioned     time series databases (TSDBs) using TLS over a spoofable infrastructure should immediately upgrade to     version 2.13.1, 2.12.6, or 2.11.11 to patch the issue. Such instances should also change the credentials     (if any) used by the TSDB writer feature to authenticate against the TSDB. There are no workarounds aside     from upgrading. (CVE-2021-37698)

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:1089-1 advisory.

  - 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.
    (CVE-2020-29663)

  - 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. (CVE-2021-32739)

  - 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.
