There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Icinga Web 2 is an open source monitoring web interface, framework and command-line interface. Between
    versions 2.3.0 and 2.8.2, the `doc` module of Icinga Web 2 allows to view documentation directly in the
    UI. It must be enabled manually by an administrator and users need explicit access permission to use it.
    Then, by visiting a certain route, it is possible to gain access to arbitrary files readable by the web-
    server user. The issue has been fixed in the 2.9.0, 2.8.3, and 2.7.5 releases. As a workaround, an
    administrator may disable the `doc` module or revoke permission to use it from all users. (CVE-2021-32746)

  - Icinga Web 2 is an open source monitoring web interface, framework, and command-line interface. A
    vulnerability in which custom variables are exposed to unauthorized users exists between versions 2.0.0
    and 2.8.2. Custom variables are user-defined keys and values on configuration objects in Icinga 2. These
    are commonly used to reference secrets in other configurations such as check commands to be able to
    authenticate with a service being checked. Icinga Web 2 displays these custom variables to logged in users
    with access to said hosts or services. In order to protect the secrets from being visible to anyone, it's
    possible to setup protection rules and blacklists in a user's role. Protection rules result in `***` being
    shown instead of the original value, the key will remain. Backlists will hide a custom variable entirely
    from the user. Besides using the UI, custom variables can also be accessed differently by using an
    undocumented URL parameter. By adding a parameter to the affected routes, Icinga Web 2 will show these
    columns additionally in the respective list. This parameter is also respected when exporting to JSON or
    CSV. Protection rules and blacklists however have no effect in this case. Custom variables are shown as-is
    in the result. The issue has been fixed in the 2.9.0, 2.8.3, and 2.7.5 releases. As a workaround, one may
    set up a restriction to hide hosts and services with the custom variable in question. (CVE-2021-32747)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
