  - Bugfixes

  - Cluster Config Sync

  - Never accept authoritative config markers from other     instances #7552

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)

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